We are asked to process a ledger of claims for a health plan with an embedded deductible structure. We need to report final components for Claims 4, 17, 21 (as they are on the books after adjustments/voids) and ending accumulators for all members and family after processing all 21 lines. The plan is Bluebonnet PPO 1500, plan year 2026. Plan specs: in-network individual deductible 1500, family 3000, embedded; out-of-network individual deductible 3000. Coinsurance in-network 20% after deductible; out-of-network 40% after deductible. Copays: PCP $30, specialist $60, urgent care $75, ER $400 (waived if admitted, then subject to deductible/coinsurance). Preventive services in-network no cost share. Copays do not count toward deductible, but count toward OOPM. OOPM: in-network individual 6000, family 12000; out-of-network individual 12000.

Accumulators: member deductible balance and OOP balance, plus family deductible balance and family OOP balance. Deductible credits from deductible_applied (the amount applied to deductible from a claim). OOP credits from member_responsibility. 

We need to process each line in order, updating accumulators accordingly. Claims are adjudicated at the time of processing, based on current accumulator balances. For adjustments, we remove the original claim's credits from all accumulators and re-adjudicate the claim with corrected values against the accumulators as they stand at the time of the adjustment. Voids remove credits and nothing is posted. 

We'll need to track for each member: deductible balance (total of deductible_applied credited), OOP balance (total member responsibility). Also family deductible balance (sum of all members' deductible_applied for in-network? Actually, family deductible is the total of all family members' deductible credits. For out-of-network, family deductible thresholds only apply to in-network; but the family deductible balance still accumulates from all deductible_applied, both in and out-of-network? Per plan: "In-network and out-of-network deductible credits accumulate to a SINGLE member deductible balance." So each member has a single deductible balance that is used for both in- and out-of-network. The family deductible balance is the sum of all members' deductible balances? Or is it a separate accumulator? The plan says: "the family deductible is also satisfied once total family credits reach the family amount." That suggests there is a family deductible balance that adds up all deductible_applied from all members. For embedded, an individual member's deductible is satisfied when either their individual balance reaches $1500 (in-network) or the family balance reaches $3000, whichever comes first. So when adjudicating an in-network claim for a member, we look at both the member's individual deductible remainder (1500 - member_balance) and the family deductible remainder (3000 - family_balance). The deductible_applied is the lesser of the allowed amount and the smaller of those two remainders (since embedded means the member can satisfy deductible through family). Actually, careful: "the smaller of the member's individual remainder and the family remainder (embedded)". So we take min(individual_remainder, family_remainder) and apply deductible_applied = min(allowed_amount, that). Then we add deductible_applied to both the member's balance and family balance. For out-of-network, the threshold is $3000 individual, and it's measured against the member's single deductible balance. The family amounts (which are in-network) do not limit out-of-network. So for out-of-network claims, deductible_applied is min(allowed_amount, max(0, 3000 - member_balance)). The family balance still gets credited with that deductible_applied, even though it's not limited by the family in-network amount.

Now OOP accumulators: Each member has an individual OOP balance. There are in-network and out-of-network OOPM thresholds. For in-network services, the member's OOP balance is capped at in-network individual OOPM ($6000). For out-of-network services, the OOP balance is capped at out-of-network individual OOPM ($12000). But the plan says: "Once a member reaches the out-of-pocket maximum the plan pays 100% of the allowed amount for covered services for the remainder of the plan year." It doesn't say that OOPM is separate per network. It says: Individual (in-network) 6000, Individual (out-of-network) 12000. So it's likely that the OOP balance is tracked per member, and when the member's OOP balance reaches the applicable threshold for the network of the service, the plan pays 100% for that service and further services of that network? Actually, it's probably: The member has a single OOP balance; if the service is in-network, the OOP max is 6000; if out-of-network, 12000. Once the OOP balance reaches the applicable threshold, the plan pays 100% for that service and beyond for that network? Realistically, the OOP balance accumulates from all cost sharing, and when it hits in-network OOPM, in-network services are covered at 100%; when it hits out-of-network OOPM, out-of-network are covered at 100%. But the thresholds are separate. We'll assume: For an in-network service, if member's OOP balance has already reached $6000 (the in-network individual OOPM), then the plan pays 100% for that service, no member responsibility. For out-of-network, if balance reaches $12000, pay 100%. The family OOPM is $12000 in-network, presumably for in-network services only? The plan lists Family (in-network) OOPM $12000. So for in-network, once the family total OOP (sum of all members' OOP) reaches $12000, then all in-network services for all members are covered at 100%? The description: "Family (in-network) .................... 12000.00" and then "Once a member reaches the out-of-pocket maximum the plan pays 100% of the allowed amount for covered services for the remainder of the plan year." It doesn't clarify family OOPM interaction. Usually, with embedded OOPM, there is an individual OOPM embedded within the family OOPM. The plan doc might not fully specify but given the deductible structure is embedded, OOPM might also be embedded. However, the plan says "Individual (in-network) ................ 6000.00" and "Family (in-network) .................... 12000.00". That could mean that the OOPM is aggregate family, but with embedded individual? Actually, it says "Embedded" only for deductible. It doesn't mention OOPM structure. But typical PPO plans have embedded OOPM as well. Given the lack of explicit "embedded" for OOPM, I'll treat OOPM as: each member has an individual OOPM for in-network of $6000, and there is a family OOPM for in-network of $12000 that once reached, in-network services for all members are covered at 100% (i.e., the plan pays 100% even if a member hasn't met individual). This is consistent with typical embedded OOPM: the family OOPM is a cap on total family out-of-pocket, but each member is also protected by an individual OOPM (lower). So a member will not pay more than $6000 in-network, and the family won't pay more than $12000 in-network total. So when adjudicating an in-network claim, we need to check if the member's individual OOP balance has reached $6000, OR if the family OOP balance has reached $12000. If either is met, then the plan pays 100% of allowed amount. For out-of-network, there's only individual OOPM $12000, no family cap, because family is only in-network. So for out-of-network, we only check if member's individual OOP balance >= $12000. OOP balance accumulates member responsibility from all claims.

Thus, we'll need to track:
- per member: deductible_balance (float, sum of deductible_applied, used for both in and out)
- per member: oop_balance (float, sum of member responsibility)
- family_deductible_balance (float, sum of all members' deductible_applied)
- family_oop_balance (float, sum of all members' oop_balance for in-network? Actually, OOP from both in and out count toward the member's OOP balance, but family OOPM likely only applies to in-network services. The plan says Family OOPM is in-network. So out-of-network OOP does not count toward the family in-network OOPM? Unclear. Typically, out-of-network spending might accumulate to a separate OOP accumulator, but the plan doc says "Family (in-network) .................... 12000.00". It doesn't mention family out-of-network OOPM. So family OOPM is only for in-network. So we should track family_oop_balance as the sum of OOP from in-network services only (since out-of-network OOP doesn't count toward that family cap). The plan: "In-network and out-of-network deductible credits accumulate to a SINGLE member deductible balance." For OOP, it's not said that it's a single balance. However, the OOPM thresholds are per network. So we'll have a member's total OOP balance (from all services) that is compared to the network-specific OOPM when adjudicating that service. But the family OOPM is specifically in-network, so only in-network OOP should count toward the family OOP balance. So I'll maintain family_oop_balance (in-network only) summing member responsibility from in-network claims. Out-of-network member responsibility does not affect family OOPM. This seems logical.

Given complexity, we'll process each line meticulously.

We'll store member objects with id: A (subscriber), B, C, D, E. They have: ded_bal, oop_bal. Also family accumulators: fam_ded_bal (total ded credits), fam_oop_in_bal (total in-network OOP). Actually, family deductible is all ded credits, regardless of network, because that's what deductibles do. For family OOP, only in-network OOP counts. So fam_oop_bal is sum of in-network member responsibility.

We'll also need to keep track of claims data for adjustments/voids. For each claim, we need to record its member, network, allowed amount, deductible_applied, member_responsibility, copay, coinsurance, etc. Also for adjustments, we need to know the original claim's credits to remove them. The prompt says: "An ADJUSTMENT line unwinds the named claim's credits from every accumulator they touched and re-adjudicates that claim at its corrected values against the accumulators as they stand at the adjustment. A VOID line unwinds the credits and posts nothing." So we need to store the original claim's deductible_applied and member_responsibility, and also the breakdown (copay, coinsurance). For re-adjudication, we need to know the original line's service type to determine copay/coinsurance rules. So we'll store sufficient info.

For each line, we'll:

- If it's a regular claim: Determine member responsibility components. First, check if preventive (in-network only): pay 100%, no cost share. Claim 19 is routine immunisation, in-network, so preventive. It will have 0 member responsibility, 0 deductible_applied. Family OOP does not increase.

- If not preventive: for in-network:
   - Determine if service is office visit (PCP copay $30, specialist $60), urgent care $75, ER $400 (if not admitted, copay; if admitted, then subject to deductible/coinsurance). In the ledger, we have descriptions. We need to distinguish. For example, Line 2: Primary care office visit -> PCP copay $30. Line 4: Urgent care visit -> $75 copay. Line 7: Outpatient rehabilitation -> not an office visit or urgent/ER, so likely subject to deductible/coinsurance. Similarly, endoscopy, procedure, allergy testing, inpatient admission, surgery, cardiac stress test, specialty pharmacy administration, ambulatory surgery. Those are not office visits, so they go to deductible/coinsurance. Unless they are ER (Line 21: Emergency department visit, treated and released -> ER copay $400, not waived because not admitted). So for Line 21, it's ER copay.

   So for a service that is subject to copay, the member pays the copay, no deductible, and copay credits OOP. For services not subject to copay, we apply deductible then coinsurance.

   However, for in-network services that are not office visit/urgent/ER, they go to deductible/coinsurance. So we calculate deductible_applied from the allowed amount, limited by the embedded deductible remainders. Then the remaining allowed amount after deductible is subject to 20% coinsurance (member coinsurance amount). That coinsurance + deductible_applied (if any) are member's cost share, but deductible_applied is part of member responsibility (they pay it). So member_responsibility = deductible_applied + coinsurance. But note: deductible_applied is capped by the deductible remainders. After deductible is exhausted, deductible_applied = 0, and coinsurance applies to full allowed amount. Also, if member's OOP balance has already hit in-network individual OOPM ($6000) OR family OOP balance hitting $12000, then plan pays 100%, and member responsibility = 0. But we must check that before applying cost sharing.

   So algorithm for in-network non-copay service:
   - Determine allowed amount AA.
   - Check OOP max: if member's oop_bal >= 6000 or fam_oop_bal >= 12000, then member_resp = 0, plan_paid = AA, deductible_applied = 0.
   - Else, compute deductible_applied:
        ind_rem = max(0, 1500 - member.ded_bal)
        fam_rem = max(0, 3000 - fam_ded_bal)
        applicable_rem = min(ind_rem, fam_rem)  # embedded
        ded_app = min(AA, applicable_rem)
        coins_amt = (AA - ded_app) * 0.20
        member_resp = ded_app + coins_amt
   - Then update accumulators: member.ded_bal += ded_app; fam_ded_bal += ded_app; member.oop_bal += member_resp; fam_oop_bal += member_resp (since in-network).
   - Plan paid = AA - member_resp.

   For in-network copay service (office visit, urgent care, ER not admitted):
   - Copay amount is flat. Member responsibility = copay, plan paid = AA - copay. No deductible. Copay credits OOP. No deductible_applied. But check OOP max first: if member.oop_bal >= 6000 or fam_oop_bal >= 12000, then member_resp = 0, plan paid = AA. Otherwise, member_resp = copay. However, note: for ER, if the visit results in inpatient admission, the copay is waived and it becomes subject to deductible/coinsurance. In this ledger, Line 21: Emergency department visit, treated and released, so copay applies.

   So we'll handle each line with its service type.

   For out-of-network services: No copay concept (the plan only lists copays for certain in-network services; out-of-network would be subject to deductible and coinsurance). So out-of-network claims (Lines 1 and 8) are deductible/coinsurance. Out-of-network preventive? Not in this ledger. So for out-of-network:
   - AA.
   - OOP max check: member's oop_bal >= out-of-network individual OOPM $12000? If yes, then member_resp = 0, plan paid = AA. (No family OOP for out-of-network.)
   - Else:
        out_ded_limit = 3000
        ded_rem = max(0, 3000 - member.ded_bal)  # same member balance, but threshold is higher
        ded_app = min(AA, ded_rem)
        coins_amt = (AA - ded_app) * 0.40
        member_resp = ded_app + coins_amt
   - Update accumulators: member.ded_bal += ded_app; fam_ded_bal += ded_app; member.oop_bal += member_resp; fam_oop_bal NOT updated (since out-of-network). No family OOP credit.

Now, adjustments: For an adjustment, we first need to recall the original claim as it was adjudicated, including its ded_app, member_resp, and whether it was in-network or out. We'll need to track all claims in a dictionary with their original and any adjustments. Since the adjustment says "unwind the credits from every accumulator they touched" – that means we subtract the original ded_app from member.ded_bal and fam_ded_bal, and subtract original member_resp from member.oop_bal and, if in-network, from fam_oop_bal. Then we re-adjudicate the claim with the new allowed amount, using the accumulators as they stand at the time of the adjustment (after processing intervening claims). This re-adjudication will produce new ded_app and member_resp, which we then add to accumulators. So we need to store for each claim: the original member, network, service type (for copay determination), allowed amount, and the resulting ded_app, member_resp, plan_paid, copay_amt, coins_amt. For adjustments, the corrected allowed amount may be different. Also, the service type remains the same, so the same rules apply (e.g., if it was a PCP visit, it's still a copay). We'll need to know if the original claim had a copay or not. For Claim 5, it's Outpatient endoscopy, in-network, no copay (not office visit/urgent/ER), so deductible/coinsurance. Claim 2 is primary care office visit, in-network, copay. Claim 4 is urgent care, in-network, copay, later voided.

We'll also need to track for void: Claim 4 is voided. So we'll process the regular claim as normal, then at the void line, we unwind its credits (remove from accumulators) and set its final components to all zero. However, the prompt asks for final components on the books for Claim 4, so after void, it should be 0.00 for all responsibility, plan paid, etc.

Claims 17 and 21 are regular claims, not adjusted or voided.

We'll process ledgers line by line, maintaining accumulators. We'll also store for each claim a record. For claims that are adjusted, we'll overwrite the record with the re-adjudicated values.

We need to be careful about family/individual deductibles and OOPM caps: When checking OOPM, the member's oop_bal might have already reached the in-network cap, so subsequent in-network claims could be 0 cost share even before the family OOPM hits. Also the family OOPM of 12000 in-network could trigger 100% payment for in-network claims if reached. For out-of-network, only the individual out-of-network OOPM matters. The family OOPM is only for in-network.

We'll simulate. Let's list the lines with descriptions and network:

1. D, Inpatient admission, out-of-network, allowed 21121.93 (no copay, deductible/coinsurance)
2. B, Primary care office visit, in-network, allowed 228.07 (PCP copay $30)
3. E, Allergy testing, in-network, allowed 2282.31 (likely no copay, deductible/coinsurance)
4. D, Urgent care visit, in-network, allowed 311.34 ($75 copay)
5. A, Outpatient endoscopy, in-network, allowed 2316.72 (no copay, deductible/coinsurance)
6. A, Outpatient procedure, in-network, allowed 8629.09 (no copay)
7. C, Outpatient rehabilitation, in-network, allowed 9053.51 (no copay)
8. B, Outpatient procedure, out-of-network, allowed 3428.25 (no copay)
9. A, Inpatient admission with surgery, in-network, allowed 25430.93 (no copay)
10. C, Primary care office visit, in-network, allowed 228.88 (copay $30)
11. A, Cardiac stress test, in-network, allowed 576.23 (no copay? testing, not office visit)
12. A, Specialty pharmacy administration, in-network, allowed 9039.75 (no copay)
13. E, Inpatient admission, in-network, allowed 22046.13 (no copay)
14. ADJ to Claim 5: A, Outpatient endoscopy, in-network, corrected allowed 2664.23 (still no copay)
15. B, Urgent care visit, in-network, allowed 227.56 (copay $75)
16. A, Inpatient admission, in-network, allowed 11401.67 (no copay)
17. A, Ambulatory surgery, in-network, allowed 6913.69 (no copay)
18. ADJ to Claim 2: B, primary care office visit, in-network, corrected allowed 136.84 (still copay)
19. E, Routine immunisation, in-network, allowed 264.92 (preventive, no cost share)
20. VOID Claim 4: D, urgent care visit, voided.
21. A, Emergency department visit, in-network, allowed 2259.30, treated and released -> ER copay $400.

Now we'll simulate step-by-step, starting with all accumulators at 0.

We'll maintain:
ded_A, oop_A; ded_B, oop_B; ded_C, oop_C; ded_D, oop_D; ded_E, oop_E.
fam_ded, fam_oop_in.

Initialize all 0.

Also, we'll keep a dictionary of claims: claim_id -> {member, network, service, allowed, ...}. We'll fill as we go.

We need to compute member responsibility components: deductible_applied, copay_amount, coinsurance_amount. For claims that are subject to copay, copay_amount = the copay, deductible_applied = 0, coinsurance_amount = 0. For deductible/coinsurance claims, copay_amount = 0, deductible_a

We need to process all lines in order, maintaining individual accumulators for A, B, C, D (deductible balance and OOP balance) and family totals (deductible and OOP). The plan is embedded, so for in-network claims, the deductible applied is the lesser of the individual's remaining individual deductible and the family's remaining deductible. For out-of-network claims, the applicable threshold is the out-of-network individual deductible (5000) but the member's single deductible balance is used; the family deductible total does not limit out-of-network claims. Out-of-network coinsurance is 50% after that deductible.

We need to track each member's deductible balance (running total of deductible_applied) and OOP balance (running total of member_responsibility). For family, we track total deductible_applied across all members (sum) and total member_responsibility across all members, but note: the family deductible threshold is 5000 (in-network). For out-of-network claims, deductible_applied goes to individual's OON deductible (5000) but not limited by family; it still adds to family deductible balance? The plan says "in-network and out-of-network deductible credits accumulate to a SINGLE member deductible balance." So each member has one deductible balance that is measured against the appropriate threshold depending on network. For in-network claims, the threshold is the embedded rule (lesser of individual remaining and family remaining). For out-of-network, the threshold is the individual OON deductible (5000). Once the balance passes the threshold, deductible_applied is 0. So we track a single deductible balance per member (and family total of all members' deductible_applied). The plan says "The amount above is the threshold that balance is measured against when the service is out-of-network." So when a member has accumulated 2500 in deductible balance, an in-network claim would apply no more deductible (because individual deductible met) but an out-of-network claim still has room up to 5000. So we need to calculate deductible_applied for each claim based on the remaining room under the applicable threshold.

Also, copays credit the deductible (and OOPM). For office visits, we have copays: primary care $25, specialist $50, urgent care $60, ER $300 (waived if admitted and then subject to deductible/coinsurance). Generic pharmacy $10. No other services mention copays, so they are subject to deductible and coinsurance after deductible. For inpatient/outpatient procedure/surgery, etc., it's deductible+coinsurance.

We need to process line by line, updating accumulators. Then after all lines, report final components for claims 15, 17, 23. For claim 17, it is voided on line 21, so its final components are all zero. But line 21 says VOID of Claim 17, so on the books, it is void: member responsibility 0, plan paid 0, deductible_applied 0, copay 0, coinsurance 0. We'll confirm.

We need to track each claim's member_responsibility, plan_paid, deductible_applied, copay_amount, coinsurance_amount. For each claim, we'll calculate.

Start with zero accumulators.

Define individual deductible threshold in-network: 2500, family in-network: 5000, OON individual: 5000. OOPM individual in-network: 5500, family in-network: 11000, individual OON: 11000. Copays credit deductible and OOP.

For each claim:
- Determine network.
- Determine service type, whether it has a copay, and if ER, whether admitted (if disposition mentions admitted, then copay waived and treated as deductible+coinsurance).
- Calculate the applicable deductible threshold:
  if in-network:
    remaining individual = max(0, 2500 - member's current deductible balance)
    remaining family = max(0, 5000 - family total deductible balance)
    applicable remaining = min(remaining individual, remaining family)
    if applicable remaining > 0, then deductible_applied = min(claim allowed amount, applicable remaining)
    else deductible_applied = 0
  if out-of-network:
    remaining OON individual = max(0, 5000 - member's current deductible balance)
    applicable remaining = remaining OON individual (no family limit)
    deductible_applied = min(claim allowed amount, applicable remaining) if remaining > 0 else 0

- After deductible_applied, remaining allowed amount after deductible = allowed - deductible_applied.
- Coinsurance: member share = remaining * coinsurance rate (30% in-network, 50% OON) UNLESS it's a service with only a copay. For office visits with copay, member pays the copay, no coinsurance, and deductible_applied = copay? Wait: copays do credit the deductible. But for a copay service, the copay is the member cost share, and that copay amount is applied toward the deductible as deductible_applied. However, the plan says: "Copays DO credit the deductible. Copays always credit the out-of-pocket maximum." So for a specialist office visit, the member cost share is $50 copay. That $50 counts as deductible_applied. There's no coinsurance because the copay is the full member responsibility. So we need to set deductible_applied = copay (subject to the remaining deductible room). If the remaining deductible room is less than the copay, then only the remaining room is applied, and the rest? It's a copay, so the member would pay the full copay regardless of deductible? Typically, copay applies after deductible? The plan says: "Member cost share: Coinsurance after deductible, in-network ... 30% ... Primary care office visit ... 25.00 copay ... Copays DO credit the deductible." It doesn't say "copay after deductible" or "copay before deductible". In many plans, copays are fixed amounts that are not subject to deductible; they apply regardless. But the rule "Copays DO credit the deductible" means that the copay payment counts toward meeting the deductible. Usually, the deductible is a threshold for coinsurance; for copay services, you pay the copay and that payment reduces your remaining deductible. So the copay is the member responsibility, and it goes to deductible_applied up to the remaining deductible limit, but the copay amount is not reduced. The plan says: "Once the applicable threshold is met, deductible_applied is 0.00, including for a copay that would otherwise credit the deductible." That implies that if the deductible is met, the copay no longer credits the deductible (i.e., deductible_applied = 0), but the copay is still charged? Actually, it says "including for a copay that would otherwise credit the deductible" meaning that if the deductible is met, then the copay does not create any deductible_applied. But the copay amount is still the member cost share. So for a copay, member_responsibility = copay amount. deductible_applied = min(copay, applicable remaining deductible). If applicable remaining is 0, deductible_applied = 0. Then the copay still counts toward OOPM. So we need to handle that.

For non-copay services (including inpatient, outpatient, surgery, etc.), member responsibility = deductible_applied + coinsurance amount (if any). For copay services, member responsibility = copay; deductible_applied = min(copay, applicable remaining deductible), but note: if the copay is more than the remaining deductible room, then only the remaining room is applied, but the member still pays full copay. That's fine.

Now, for out-of-network office visits: the plan has copays for primary care, specialist, urgent care, ER – but likely only for in-network? The plan document doesn't specify that copays are only in-network. Usually copays apply to in-network. It says "Primary care office visit ... 25.00 copay" etc., under "Member cost share". It doesn't say "in-network" separately. But it's typical that copays are for in-network. However, the plan also has out-of-network coinsurance. So I think the copay only applies to in-network office visits. Out-of-network office visits would be subject to deductible and coinsurance (50%). The plan document does not state "out-of-network office visits have copay", so we'll assume copay is only for in-network. So we'll use the service type: if it's and "office visit" and in-network, we check if it's primary care, specialist, urgent care, ER. The claim descriptions: specialist office visit (Claim 5, B, in-network), so it's a specialist copay $50. Claim 18: emergency department visit, in-network, and disposition admitted, so copay waived, becomes deductible+coinsurance. For other services, no copay.

Now let's process.

Initialize accumulators:
A: ded_bal=0, oop_bal=0
B: ded_bal=0, oop_bal=0
C: ded_bal=0, oop_bal=0
D: ded_bal=0, oop_bal=0
Family ded_total=0, oop_total=0 (sum of deductible_applied and oop across members, but note family oop total is sum of member responsibilities? Yes, OOPM is individual and family; family OOPM is 11000 in-network, but that's the ceiling for in-network member cost share? Actually, plan says "Out-of-pocket maximum Individual (in-network) 5500.00 Family (in-network) 11000.00 Individual (out-of-network) 11000.00". So the OOPM applies to cost share. Once a member reaches the OOPM, the plan pays 100% for covered services. The family OOPM of 11000 is for in-network; it likely applies to total family in-network cost share, but the individual OOPM caps each member anyway. We need to track OOP balances per member and family total OOP. For OOPM, when a member's OOP balance reaches their applicable OOPM (5500 in-network or 11000 OON), then any further in-network claims for that member will have $0 member responsibility? But OON OOPM is higher; once a member's OOP balance (all cost share) reaches 11000, then even OON claims are 100% plan paid. But for family in-network OOPM, total family OOP (sum of all member cost share) reaching 11000 would mean all covered in-network services after that are 100% paid? However, the family OOPM is typically an aggregate cap that limits total family cost sharing. But the plan has individual OOPMs embedded? It says "Once a member reaches the out-of-pocket maximum the plan pays 100% of the allowed amount for covered services for the remainder of the plan year." It doesn't say that the family OOPM triggers when total reaches 11000; it just lists the family OOPM. In typical embedded OOPM, each member is protected by their individual OOPM, and the family OOPM is the maximum total family cost share (like embedded OOP). So if total family OOP reaches 11000, then even if individual members haven't hit their individual OOPM, they'd be covered? The plan doc just says "Out-of-pocket maximum Individual (in-network) 5500.00, Family (in-network) 11000.00". It doesn't specify how the family OOPM works. Usually, for an embedded plan, the family OOPM is the maximum aggregate cost share; once total family cost share hits that, all members are considered to have met OOPM. But the plan says "Once a member reaches the out-of-pocket maximum the plan pays 100%...". It's ambiguous. However, the "glossary" defines "Out-of-pocket maximum (OOPM): the ceiling on member cost share for the plan year. Once reached, the plan pays 100% of the allowed amount for covered in-network services." It doesn't say "once a member reaches", it says "Once reached". So the OOPM is a ceiling that when total member cost share (maybe per member or per family?) reaches the applicable limit, the plan covers fully. The plan doc says "Individual" and "Family". So I think the individual OOPM applies to each member individually: when a member's own OOP balance reaches the individual OOPM (5500 in-net, 11000 out-net), then that member's covered services are paid at 100%. The family OOPM (11000) would be an aggregate cap for the family; if combined family OOP reaches 11000, then all members become fully covered regardless of individual balances? That's typical. But the prompt doesn't elaborate. We need to interpret from the plan document. It says: "Out-of-pocket maximum Individual (in-network) ................ 5500.00 Family (in-network) .................... 11000.00 Individual (out-of-network) ............ 11000.00 Once a member reaches the out-of-pocket maximum the plan pays 100% of the allowed amount for covered services for the remainder of the plan year." It says "Once a member reaches the out-of-pocket maximum"... So it's per-member. The family OOPM likely works similarly: once the family total OOP reaches 11000, then all members have reached the OOPM, but maybe only for in-network? The OOPM for in-network services is 5500 individual, 11000 family. For OON, only individual 11000. I'll assume: For each in-network claim, we check the member's individual OOP balance against 5500; if the member's OOP balance before the claim is >=5500, then member responsibility is 0 for in-network services (and no deductible). For out-of-network, we check against 11000. Additionally, the family in-network OOPM of 11000 acts as an aggregate: if total family OOP (all members) before the claim is >=11000, then maybe all in-network member cost share is 0. But unclear. However, typical embedded OOP works like: individual OOP limits protect each member; the family OOP limit caps total family cost sharing. So if a member hasn't hit their individual limit but the family limit is reached, then that member's cost share would be zero. The plan document didn't explicitly state that, but it's reasonable. The glossary says: "Out-of-pocket maximum (OOPM): the ceiling on member cost share for the plan year. Once reached, the plan pays 100% of the allowed amount for covered in-network services." It does not specify individual vs family; it says "the ceiling", so I think the applicable OOPM is the individual OOPM for that member (in-network 5500) and the family OOPM (11000) is an aggregate ceiling for the whole family's in-network cost share. So we need to track total family OOP (sum of all member OOP balances). For in-network claims, if either the member's individual OOP balance >= 5500 OR the total family OOP balance >= 11000, then the member's cost share for in-network services is 0? Typically, the family OOPM is a cap on total family cost sharing; once total family cost sharing reaches 11000, then all further in-network cost sharing for any member is covered at 100%. Since the plan says "Once a member reaches the out-of-pocket maximum" and lists family OOPM, I'd interpret that as: the OOPM for in-network is the lower of individual OOPM per member and the family OOPM aggregate. When total family OOP reaches 11000, then all members have "reached" the OOPM for in-network purposes. For out-of-network, only individual OOPM 11000 applies; no family OOPM is listed for OON, so no family cap for OON. I'll proceed with: For an in-network claim, before computing cost share, check if member_oop_balance >= 5500 OR family_oop_total >= 11000. If either true, then member responsibility = 0 (and thus no deductible applied). For out-of-network claim, check if member_oop_balance >= 11000 (or family OOP total? No family OON OOPM, so only member). If true, then member responsibility = 0. But note: OOPM also applies to copays; copays count toward OOP.

Also note: For preventive care in-network, 100% covered, no cost share, no accumulator movement. But none of the claims appear preventive, so ignore.

Now process lines.

Line 1: Claim 1, A, in-network, outpatient procedure. No copay.
Allowed: 6138.52.
Deductible applicable: in-network. A's ded_bal=0, family ded_total=0. Remaining individual: 2500-0=2500, family: 5000-0=5000, applicable = min(2500,5000)=2500.
deductible_applied = min(6138.52, 2500) = 2500.
Remaining allowed after ded: 6138.52 - 2500 = 3638.52.
Coinsurance member: 30% of 3638.52 = 1091.556, round to 1091.56.
Member responsibility = 2500 + 1091.56 = 3591.56.
Plan paid = 6138.52 - 3591.56 = 2546.96. (Check: 70% of 3638.52 = 2546.964 -> 2546.96).
Copay_amount = 0, coinsurance_amount = 1091.56.
Update accumulators:
A's ded_bal = 2500, A's oop_bal = 3591.56.
Family ded_total = 2500, family oop_total = 3591.56.

Line 2: Claim 2, D, out-of-network, ambulatory surgery (no copay). Allowed: 2734.12.
D's ded_bal=0, OON threshold 5000, remaining = 5000.
deductible_applied = min(2734.12, 5000) = 2734.12 (no family limit).
Remaining: 2734.12 - 2734.12 = 0.
Coinsurance: 50% of 0? Actually after applying full allowed to deductible, there's no remaining, so coinsurance = 0. So member responsibility = deductible_applied = 2734.12. Plan paid = 0.
Copay=0, coinsurance=0.
Update: D's ded_bal = 2734.12, D's oop_bal = 2734.12.
Family ded_total = 2500 (A) + 2734.12 (D) = 5234.12. Family oop_total = 3591.56 + 2734.12 = 6325.68.

Line 3: Claim 3, A, in-network, inpatient admission. No copay. Allowed: 11894.44.
A's current ded_bal = 2500, so individual remaining = 2500 - 2500 = 0. Family ded_total = 5234.12, family remaining = max(0, 5000 - 5234.12) = 0? Since family total is already >5000, family remaining = 0. So applicable remaining = min(0, 0) = 0. So deductible_applied = 0.
Now check OOP: A's oop_bal = 3591.56, which is < 5500. Family oop_total = 6325.68, < 11000. So no OOPM trigger.
Coinsurance: member 30% of allowed (since deductible already met). But wait: coinsurance is "after deductible". Since deductible_applied=0, it means the deductible threshold is already met, so the entire allowed is subject to coinsurance. Yes.
Member coinsurance = 30% * 11894.44 = 3568.332 -> 3568.33.
Member responsibility = 3568.33 (no deductible applied).
Plan paid = 70% * 11894.44 = 8326.108 -> 8326.11 (or 11894.44 - 3568.33 = 8326.11). Good.
Copay=0, coinsurance=3568.33.
Update: A's ded_bal stays 2500, A's oop_bal = 3591.56 + 3568.33 = 7159.89.
Family ded_total unchanged (2500+2734.12=5234.12). Family oop_total = 6325.68 + 3568.33 = 9894.01.

Line 4: Claim 4, B, in-network, ambulatory surgery. No copay. Allowed: 8808.44 originally.
B's ded_bal = 0, family ded_total = 5234.12 (already >5000). So individual remaining = 2500 - 0 = 2500, family remaining = max(0, 5000 - 5234.12) = 0 (since family total exceeds 5000, the family deductible is already met). So applicable remaining = min(2500, 0) = 0. Thus deductible_applied = 0. Entire allowed subject to coinsurance.
Check OOP: B's oop_bal = 0, so OOP under 5500. Family oop = 9894.01, still < 11000.
Coinsurance: 30% of 8808.44 = 2642.532 -> 2642.53.
Member responsibility = 2642.53.
Plan paid = 8808.44 - 2642.53 = 6165.91 (70% 6165.908 -> 6165.91). OK.
Accumulators: B's ded_bal remains 0? Actually deductible_applied was 0, so ded_bal stays 0. B's oop_bal = 2642.53. Family ded_total unchanged (5234.12). Family oop_total = 9894.01 + 2642.53 = 12536.54.

Line 5: Claim 5, B, in-network, specialist office visit. Copay $50. Allowed: 372.91 originally.
Specialist copay applies. Member responsibility = copay = 50.
Now deductible_applied: Since it's a copay service that credits deductible, we need to apply deductible_applied = min(copay, applicable remaining deductible). B's ded_bal is 0, family ded_total = 5234.12 (already >= 5000). So family remaining = 0. Individual remaining = 2500-0=2500. Applicable = min(2500, 0) = 0. So deductible_applied = 0 (since applicable remaining is 0). The copay still credits OOP, but no deductible credited because no room.
Member responsibility = 50.
Plan paid = 372.91 - 50 = 322.91.
Copay_amount = 50, coinsurance_amount=0.
Update: B's ded_bal unchanged (0), B's oop_bal = 2642.53 + 50 = 2692.53.
Family oop_total = 12536.54 + 50 = 12586.54. Family ded_total unchanged.

Line 6: Claim 6, B, out-of-network, outpatient infusion. No copay. Allowed: 722.55.
B's ded_bal = 0. OON threshold: 5000. Remaining = 5000. So deductible_applied = min(722.55, 5000) = 722.55.
Remaining allowed = 0. Coinsurance = 0.
Member responsibility = 722.55.
Plan paid = 0.
Update: B's ded_bal becomes 722.55, B's oop_bal = 2692.53 + 722.55 = 3415.08.
Family ded_total = 5234.12 (prev) + 722.55 = 5956.67. Family oop_total = 12586.54 + 722.55 = 13309.09.

Line 7: Claim 7, B, in-network, ambulatory surgery. Allowed: 7877.07. No copay.
B's ded_bal currently 722.55. Individual remaining = 

We need to process the ledger line by line, updating accumulators for each member and the family. The plan is aggregate deductible (family in-network 6400, no individual in-network deductible). Out-of-network individual deductible is 6400, measured against the same single deductible balance. So the deductible balance for a member is the total of all deductible_applied amounts (in-network and out-of-network) up to the applicable threshold for the service. For in-network, the threshold is the family deductible (6400) aggregate: no member gets coinsurance until total family deductible credits reach 6400. For out-of-network, the threshold is the individual out-of-network deductible (6400), and the member's own balance is measured against that. But note: "In-network and out-of-network deductible credits accumulate to a SINGLE member deductible balance. The amount above is the threshold that balance is measured against when the service is out-of-network." So each member has a single deductible balance (the total deductible_applied they've generated). For in-network services, the deductible_applied is limited by the family deductible remaining (aggregate) and also by the member's individual balance? Under aggregate, the plan pays no coinsurance for any member until total family credits reach the family deductible amount. So the deductible_applied for an in-network claim is the lesser of the allowed amount and the room left under the family deductible (6400 - family_deductible_balance). There is no individual deductible limit for in-network; the member's individual balance is not a cap. So for in-network, the deductible_applied is the amount needed to fill the family deductible if it hasn't been met. Once family deductible is met, deductible_applied = 0 for in-network, and the claim goes to coinsurance (10% member). For out-of-network, the deductible_applied is the lesser of allowed amount and the room left under the member's individual out-of-network deductible threshold (6400) minus the member's current deductible balance. So it's measured against the member's single deductible balance compared to 6400. The member's single deductible balance includes all deductible_applied from both in- and out-of-network. So if the member's balance is already >= 6400, then out-of-network deductible_applied = 0, and the claim goes to coinsurance (40% member). The family deductible balance is the sum of all deductible_applied from all members for in-network claims? Actually, the family deductible is the total family credits that count toward the family deductible. The plan says "Deductible credits accumulate to a SINGLE member deductible balance." And "Family deductible: 6400. Structure: Aggregate — the plan pays no coinsurance for any member until total family credits reach the family deductible amount." So the family deductible is the total of deductible_applied from all members for in-network claims? But out-of-network claims also generate deductible credits that go to the member's balance, but do they also go to the family deductible? The document says "In-network and out-of-network deductible credits accumulate to a SINGLE member deductible balance." That implies that the member's deductible balance is the sum of all deductible_applied from any network. The family deductible threshold is an in-network amount. Under aggregate structure, the family deductible is the amount that must be met before the plan pays coinsurance for any in-network service. So the family deductible balance is the sum of all deductible_applied from all members for in-network services? Or does it include out-of-network credits? Typically, aggregate deductible means the family must meet the family deductible amount (which is in-network) before any member gets coinsurance for in-network services. Out-of-network services are not subject to the family deductible, but they may still contribute to the member's individual deductible balance. However, the plan says "In-network and out-of-network deductible credits accumulate to a SINGLE member deductible balance." That's about the member's balance. Does the family deductible also accumulate out-of-network credits? The document doesn't explicitly say that out-of-network credits count toward the family deductible. Usually, family deductible is only for in-network services. But the plan says: "Deductible credits accumulate to a SINGLE member deductible balance." That's separate. For family deductible, we need to know what credits count. The family deductible is an in-network amount. Under aggregate, "the plan pays no coinsurance for any member until total family credits reach the family deductible amount." So what are "family credits"? Likely the sum of deductible_applied from all members for in-network services only. Because out-of-network deductible is separate, and the family deductible is in-network. I'll assume that only in-network deductible_applied amounts count toward the family deductible. The plan's out-of-network section says "Out-of-network deductible (individual) 6400.00" and that the member's deductible balance is measured against that threshold for out-of-network. It doesn't mention family out-of-network deductible. So out-of-network claims do not contribute to the family deductible, only to the member's individual deductible balance. But the member's deductible balance is the same single balance for both networks. So when an out-of-network claim generates deductible_applied, it increases the member's balance, but does not increase the family deductible balance. That is the standard interpretation in aggregate deductible plans: out-of-network deductible is separate and only in-network accumulations count toward the family in-network deductible. We'll confirm: The plan document says "Family (in-network) .................... 6400.00" and "Deductible credits accumulate to a SINGLE member deductible balance." It doesn't say that out-of-network credits count toward the family deductible. And the structure: "AGGREGATE — the plan pays no coinsurance for any member until total family credits reach the family deductible amount." I think "family credits" are the in-network deductible_applied credits. So I'll track family deductible as the sum of all in-network deductible_applied amounts across all members.

Now, out-of-pocket maximum: Individual in-network 7000, family in-network 14000, individual out-of-network 14000. The plan says "Once a member reaches the out-of-pocket maximum the plan pays 100% of the allowed amount for covered services for the remainder of the plan year." Which OOPM applies? For in-network services, the member's cost share (deductible and coinsurance) counts toward the in-network individual OOPM. For out-of-network, it counts toward the out-of-network individual OOPM (14000). But the plan also has a family OOPM of 14000 in-network. The plan says "Once a member reaches the out-of-pocket maximum the plan pays 100% of the allowed amount for covered services for the remainder of the plan year." It doesn't specify which OOPM applies to which service. Typically, the in-network OOPM applies to in-network services, and the out-of-network OOPM applies to out-of-network services. And the family OOPM is the overall cap for in-network cost sharing for the family. So we need to track member's in-network OOP balance (cost share from in-network services) and out-of-network OOP balance (cost share from out-of-network services). The plan says "Individual (in-network) ................ 7000.00", "Individual (out-of-network) ............ 14000.00", "Family (in-network) .................... 14000.00". So for in-network services, the member's cost share counts toward their individual in-network OOPM (7000) and also toward the family in-network OOPM (14000). Once either the individual reaches 7000 or the family reaches 14000, the plan pays 100% for that member's in-network services? Typically, family OOPM is a cap on total in-network cost sharing for the family; if the family reaches 14000, then all family members' in-network services are covered at 100% for the rest of the year. So we need to track both individual in-network OOP balances and family in-network OOP balance. The out-of-network OOPM is individual only (14000), and out-of-network cost share does not count toward the in-network OOPM. The document says "Once a member reaches the out-of-pocket maximum the plan pays 100% of the allowed amount for covered services for the remainder of the plan year." That is ambiguous which maximum. I'll interpret that for in-network services, the relevant OOPM is the in-network individual OOPM, but if the family OOPM is met, then all in-network services are covered at 100% regardless of individual. For out-of-network services, the relevant OOPM is the out-of-network individual OOPM. Out-of-network cost share does not count toward the in-network OOPM. So we'll track: for each member, an in-network OOP balance (member_responsibility from in-network claims) and an out-of-network OOP balance (member_responsibility from out-of-network claims). Also a family in-network OOP balance (sum of all in-network member_responsibility across all members). When a member's in-network OOP balance reaches 7000, any further in-network cost share for that member is 0. When the family in-network OOP balance reaches 14000, all further in-network cost share for all members is 0. The out-of-network OOP balance is separate; when it reaches 14000, further out-of-network cost share for that member is 0. The family OOP does not apply to out-of-network.

Now, preventive services: In-network preventive are covered at 100%, no cost share, no accumulator movement. Out-of-network preventive are not covered at 100%; they are subject to out-of-network deductible and coinsurance. Line 5: C (child) Annual wellness visit, out-of-network. That's a preventive service but out-of-network, so it is subject to out-of-network deductible and coinsurance. So it will be processed as an out-of-network claim.

Start with given accumulators before line 1:
A: deductible balance = 1729.94, OOP in-network? The out-of-pocket given is 1762.13. Since it's before any claims, it's likely the in-network OOP balance (since A had only in-network services so far, presumably). The family total OOP is 3708.11, which is sum of A's and C's OOP. So A's OOP 1762.13 is in-network, C's 1945.98 is in-network? B's is 0. So we'll assume those are in-network OOP balances. The out-of-network OOP balances are 0 initially for all because no out-of-network claims yet. So we'll track:
A: in-network OOP = 1762.13, out-of-network OOP = 0.00
B: in-network OOP = 0.00, out-of-network OOP = 0.00
C: in-network OOP = 1945.98, out-of-network OOP = 0.00
Family in-network OOP = 1762.13 + 0 + 1945.98 = 3708.11
Family deductible balance = 3112.34 (sum of in-network deductible_applied across all members). A's deductible balance is 1729.94 (total of all deductible_applied from any network). B's 0, C's 1382.40. So family deductible balance = sum of in-network deductible_applied. Since A and C have balances, it's likely that all those were from in-network claims. So family deductible = 3112.34. So we'll keep that.

Now process each line.

Line 1: Claim 1, A, in-network, allowed 1553.18. Is it preventive? Physical therapy course, not preventive. So it's subject to in-network deductible and coinsurance. Family deductible remaining = 6400 - 3112.34 = 3287.66. The allowed amount 1553.18 is less than remaining, so full allowed goes to deductible. Deductible_applied = 1553.18. Member responsibility = deductible_applied = 1553.18 (since deductible phase). No coinsurance. Plan pays 0? Actually plan pays the rest of allowed after member responsibility? The allowed amount is 1553.18, member pays 1553.18, plan pays 0. So member_responsibility = 1553.18, plan_paid = 0.00. Update accumulators: A's deductible balance increases by 1553.18 -> 1729.94+1553.18=3283.12. Family deductible increases by 1553.18 -> 3112.34+1553.18=4665.52. A's in-network OOP increases by 1553.18 -> 1762.13+1553.18=3315.31. Family in-network OOP increases by 1553.18 -> 3708.11+1553.18=5261.29. Check OOP caps: A's in-network OOP 3315.31 < 7000, family in-network OOP 5261.29 < 14000, so no OOPM triggered. A's out-of-network OOP unchanged 0.

Line 2: Claim 2, A, in-network, allowed 21710.91. Family deductible remaining = 6400 - 4665.52 = 1734.48. So deductible_applied = 1734.48 (the remaining to fill family deductible). Then after that, family deductible is met. Then coinsurance applies to the remainder: 21710.91 - 1734.48 = 19976.43. Coinsurance 10% member = 1997.64 (rounded half up to cent). So member responsibility = deductible_applied + coinsurance = 1734.48 + 1997.64 = 3732.12. Plan paid = 21710.91 - 3732.12 = 17978.79. Update accumulators: deductibles: A's deductible balance +1734.48 (since deductible_applied) -> 3283.12+1734.48=5017.60. Family deductible +1734.48 -> 4665.52+1734.48=6400.00 exactly met. A's in-network OOP: 3315.31 + 3732.12 = 7047.43. Check OOP cap: A's in-network OOP reaches 7000? The OOP maximum is 7000. Once a member reaches the OOPM, the plan pays 100% for the remainder of the plan year. But here the claim itself pushes the OOP balance above 7000. The member's cost share for this claim would be capped such that the total OOP does not exceed 7000. How to handle? Typically, the member's responsibility for the claim is limited so that the member's OOP balance does not exceed the OOPM. So we need to calculate the maximum member responsibility that would bring the OOP balance to exactly 7000. A's in-network OOP before this claim is 3315.31. The maximum additional member responsibility that would bring it to 7000 is 7000 - 3315.31 = 3684.69. The claim's member responsibility without OOP cap would be 3732.12, which exceeds 3684.69. So the member responsibility is capped at 3684.69. The plan pays the rest: 21710.91 - 3684.69 = 18026.22. How to split the member responsibility between deductible and coinsurance? The deductible_applied is still the amount needed to fill family deductible, which is 1734.48. Then the coinsurance amount would be the remainder of the member responsibility, which is 3684.69 - 1734.48 = 1950.21. So we report deductible_applied = 1734.48, coinsurance = 1950.21, copay = 0. Member responsibility = 3684.69. Plan paid = 18026.22. Then A's in-network OOP becomes 3315.31 + 3684.69 = 7000.00 exactly. So A hits the individual in-network OOPM. The family in-network OOP: before = 5261.29, add 3684.69 = 8945.98. That's still less than 14000. So A's future in-network claims will have 0 member responsibility (since A reached individual OOPM). But family OOPM not yet reached. For B and C, they still have to pay cost share until family OOPM is reached or their own individual OOPM.

Line 3: Claim 3, C, in-network, allowed 454.13. Family deductible is already met (6400), so deductible_applied = 0. Coinsurance: member 10% = 45.41 (rounded: 454.13*0.10 = 45.413 -> 45.41). So member responsibility = 45.41. Plan paid = 454.13 - 45.41 = 408.72. Update: C's in-network OOP: 1945.98 + 45.41 = 1991.39. Family in-network OOP: 8945.98 + 45.41 = 8991.39. Deductibles: A's deductible balance unchanged 5017.60, C's deductible balance unchanged 1382.40 (since no deductible applied). Family deductible stays 6400. No OOP cap triggered.

Line 4: Claim 4, A, in-network, allowed 17679.63. Since A has already hit individual in-network OOPM (7000), member responsibility for this in-network claim is 0. So plan pays 100% = 17679.63. Deductible_applied = 0, coinsurance = 0, copay = 0. Accumulators: A's in-network OOP stays 7000.00, family in-network OOP unchanged (no additional). Deductibles unchanged.

Line 5: Claim 5, C, out-of-network, allowed 771.12. Service is annual wellness visit, out-of-network. Since it's out-of-network, it's subject to out-of-network deductible and coinsurance. Determine deductible_applied: C's deductible balance is 1382.40 (single balance). Out-of-network individual deductible threshold is 6400. So remaining = 6400 - 1382.40 = 5017.60. Allowed 771.12 is less than remaining, so full amount goes to deductible. Deductible_applied = 771.12. Then member responsibility = deductible_applied = 771.12. Coinsurance 0. Plan pays 0? Actually out-of-network coinsurance is 40% after deductible, but deductible not met so 0 coinsurance. So plan paid = 0.00. Update: C's deductible balance increases by 771.12 -> 1382.40+771.12=2153.52. Family deductible remains 6400 (since out-of-network does not count toward family deductible). C's out-of-network OOP: currently 0, add 771.12 -> 771.12. This is towards out-of-network OOPM (14000). C's in-network OOP unchanged (1991.39). Family in-network OOP unchanged (8991.39). No OOP caps.

Line 6: Claim 6, A, out-of-network, allowed 25351.30. A's deductible balance is 5017.60. Out-of-network deductible threshold 6400. Remaining = 6400 - 5017.60 = 1382.40. So deductible_applied = 1382.40 (the amount to fill the out-of-network deductible). Then the remainder of allowed: 25351.30 - 1382.40 = 23968.90. Coinsurance is 40% member = 9587.56 (23968.90 * 0.40 = 9587.56). So member responsibility = 1382.40 + 9587.56 = 10969.96. Plan paid = 25351.30 - 10969.96 = 14381.34. Check OOP caps: A's out-of-network OOP is currently 0. Add 10969.96. The out-of-network individual OOPM is 14000. So 10969.96 is less than 14000, so no cap. Update: A's deductible balance increases by 1382.40 -> 5017.60+1382.40=6400.00 exactly. A's out-of-network OOP becomes 10969.96. Family deductible unchanged (6400). A's in-network OOP unchanged (7000). Family in-network OOP unchanged. No OOP caps triggered.

Line 7: Claim 7, C, in-network, allowed 816.06. Family deductible is met, so deductible_applied=0. Coinsurance 10% = 81.61 (816.06*0.10=81.606 -> 81.61). Member responsibility = 81.61. Plan paid = 816.06 - 81.61 = 734.45. Update: C's in-network OOP: 1991.39 + 81.61 = 2073.00. Family in-network OOP: 8991.39 + 81.61 = 9073.00. No caps.

Line 8: Claim 8, C, in-network, allowed 261.28. Coinsurance 10% = 26.13 (261.28*0.10=26.128 -> 26.13). Member responsibility = 26.13. Plan paid = 235.15. Update: C's in-network OOP: 2073.00 + 26.13 = 2099.13. Family in-network OOP: 9073.00 + 26.13 = 9099.13.

Line 9: Claim 9, A, in-network, allowed 9541.82. A has individual in-network OOPM met (7000), so member responsibility = 0. Plan pays 9541.82. No accumulator changes.

Line 10: Claim 10, C, in-network, allowed 6734.20. Coinsurance 10% = 673.42 (6734.20*0.10=673.42). Member responsibility = 673.42. Plan paid = 6060.78. Update: C's in-network OOP: 2099.13 + 673.42 = 2772.55. Family in-network OOP: 9099.13 + 673.42 = 9772.55. No OOP caps.

Line 11: VOID of Claim 1. We need to remove the credits of Claim 1 from all accumulators it touched. Claim 1 was: A, in-network, allowed 1553.18, deductible_applied 1553.18, member responsibility 1553.18. That contributed to A's deductible balance, family deductible, A's in-network OOP, family in-network OOP. So we subtract those amounts: A's deductible balance: 6400.00 - 1553.18 = 4846.82. Family deductible: 6400.00 - 1553.18 = 4846.82. A's in-network OOP: 7000.00 - 1553.18 = 5446.82. But careful: A's in-network OOP was 7000.00 after line 2. So reversing 1553.18 reduces it to 5446.82. Family in-network OOP: 9772.55 - 1553.18 = 8219.37. Also, A's in-network OOPM is no longer met? The OOPM is a threshold; once reached, it stays reached for the year? Actually, the plan says "Once a member reaches the out-of-pocket maximum the plan pays 100% of the allowed amount for covered services for the remainder of the plan year." So if a member reaches the OOPM, it's a permanent status for the year. However, if a claim that contributed to reaching the OOPM is voided, does the OOPM status revert? Typically, yes, because the OOPM is based on the accumulated cost sharing. If the cost sharing is reversed, the member may no longer have met the OOPM. So 

We are asked to process a ledger of claims under a Trinity HDHP 3200 plan. Plan details: aggregate deductible $6400 family in-network, no individual deductible. Out-of-network individual deductible $6400. Out-of-pocket max individual in-network $7000, family in-network $14000, individual out-of-network $14000. Coinsurance in-network 10% after deductible, out-of-network 40%. No copays. Preventive in-network no cost share. The family is aggregate, meaning no coinsurance for any member until total family deductible credits reach $6400. So for in-network claims, deductible is applied until family deductible met, then coinsurance. For out-of-network claims, they are measured against individual out-of-network deductible $6400, but the credit goes to the member's deductible balance and family deductible balance. The out-of-network deductible is higher, so it can cause the member's balance to exceed in-network individual amount. The family deductible is only in-network threshold, but out-of-network claims still accumulate to family deductible balance (the "family total deductible" accumulator is the sum of deductible_applied across all claims). So we need to track each member's deductible balance (which is the sum of deductible_applied for that member from all claims) and family deductible balance (sum of all deductible_applied across all members). The aggregate structure: for an in-network claim, coinsurance begins only when family deductible balance >= $6400. That means we check the family deductible balance before the claim. If it's less than $6400, then the claim can apply deductible, but the amount applied is limited by the remaining family deductible ($6400 - current family balance). For out-of-network claim, it uses the member's individual deductible balance against the OON deductible threshold $6400. So we need to track each member's individual deductible balance (the total of their deductible_applied) and family deductible balance (sum of all members' deductible_applied). The OON deductible is measured against the member's same single deductible balance. So if a member has accumulated some deductible from in-network claims, that counts toward their OON deductible. For an OON claim, we check the member's current deductible balance (which is the sum of all deductible_applied for that member). If it's less than $6400, then deductible is applied up to the remaining to reach $6400. That amount is added to that member's balance and to family balance. Then after OON deductible is met, coinsurance 40% applies. But careful: the OON claim's coinsurance is based on allowed amount minus deductible applied (if any) times 40%. The member's OOPM accumulation includes all member responsibility (deductible + coinsurance). And the OOPM thresholds: for in-network claims, OOPM individual $7000, family $14000. For out-of-network claims, the individual OOPM is $14000. When a member hits their OOPM, plan pays 100% for covered services (presumably for in-network and out-of-network? But the plan says: "Once a member reaches the out-of-pocket maximum the plan pays 100% of the allowed amount for covered services for the remainder of the plan year." It doesn't distinguish network, so I think after hitting any OOPM, all services are paid 100%. But careful: The OOPM table lists individual in-network $7000, family in-network $14000, individual out-of-network $14000. Typically, out-of-network OOPM is separate, but the plan says "Once a member reaches the out-of-pocket maximum the plan pays 100%...". It might be that the out-of-pocket maximum applicable to the service is the one that matters. Usually, in-network OOPM and out-of-network OOPM are separate. The plan document lists them separately. So I'll assume that for in-network services, the OOPM to consider is the individual in-network $7000, and for out-of-network services, the OOPM is the individual out-of-network $14000. However, the document says: "Out-of-pocket maximum Individual (in-network) 7000.00 Family (in-network) 14000.00 Individual (out-of-network) 14000.00 Once a member reaches the out-of-pocket maximum the plan pays 100% of the allowed amount for covered services for the remainder of the plan year." It doesn't specify which OOPM applies when. But typical interpretation: in-network claims use in-network OOPM, out-of-network claims use out-of-network OOPM. Also, the family OOPM applies to in-network only? The family OOPM is listed under in-network, so likely only for in-network services. So for out-of-network, there's no family OOPM; only individual OOPM $14000. I'll proceed with that: in-network claims check individual in-network OOPM (and family in-network OOPM for all members combined? Actually, family OOPM is an aggregate cap on all family members' in-network cost sharing. Once the family reaches $14000 in in-network member responsibility, all in-network services are paid 100% for all members. But careful: the document says "Once a member reaches the out-of-pocket maximum the plan pays 100%...". It's ambiguous. But typical HDHP: Family OOPM is the maximum total cost sharing for the family; when the family total member responsibility reaches that amount, all members are covered at 100%. The document: "Once a member reaches the out-of-pocket maximum the plan pays 100% of the allowed amount for covered services for the remainder of the plan year." That phrase "a member reaches" suggests it's per-member. However, family OOPM may also apply: if the family as a whole reaches family OOPM, then all members get 100% coverage. I'll interpret as: each member has an individual OOPM for in-network ($7000) and out-of-network ($14000). In addition, there's a family OOPM for in-network ($14000) that caps total family in-network cost sharing. Once the family in-network cost sharing hits $14000, all in-network services for all members are paid at 100% (no more cost sharing). Similarly, for out-of-network, there's no family OOPM, so only individual $14000. I'll track each member's in-network OOP accumulation and out-of-network OOP accumulation separately? Actually, the plan says "In-network and out-of-network deductible credits accumulate to a SINGLE member deductible balance." But for OOPM, it doesn't say they accumulate together. Typically, OOPM accumulations are separate: in-network cost sharing counts toward in-network OOPM, out-of-network cost sharing counts toward out-of-network OOPM. The plan lists separate OOPM amounts for in and out. So I'll assume in-network member responsibility counts toward the in-network individual OOPM and family OOPM. Out-of-network member responsibility counts toward the out-of-network individual OOPM only, not the family OOPM. This is consistent with typical plans.

We have adjustments and voids. Line 9 adjusts Claim 3 (allowed amount changed). Line 11 voids Claim 7. So need to process ledger in order, applying each claim and then later undoing and redoing for adjustment/void.

Let's start with initial accumulators all zero.

Define for each member: deductible balance (total of deductible_applied across all claims), in_network_oop (total member responsibility for in-network claims), out_of_network_oop (total member responsibility for out-of-network claims). Also family deductible balance (sum of all members' deductible_applied). Family in-network OOP: sum of in_network_oop across members (since family OOPM applies to in-network). The family OOPM threshold $14000 applies to total in-network member responsibility across all members, but I need to see if it impacts claims when family OOPM is reached. The family OOPM is for in-network services. So for in-network claims, after family OOPM is met, the plan pays 100% (no member responsibility). But also individual OOPM may be met. Since family OOPM is lower than sum of individual OOPMs ($14000 vs 4*7000=$28000), it can be met earlier. I'll check family in-network OOP accumulation before each in-network claim. If it has already reached $14000, then member responsibility is 0 and plan pays 100%. If not, then calculate normally, but also cap member responsibility so that the member's own individual in-network OOP doesn't exceed $7000, and the total family in-network OOP after this claim doesn't exceed $14000. The typical order: first apply deductible (if family deductible not met), then coinsurance, but then cap member responsibility by the OOPM limits. The plan says: "Once a member reaches the out-of-pocket maximum the plan pays 100%...". So for individual OOPM, if the member's in-network OOP accumulation prior to the claim is already >= $7000, then member responsibility is 0 for in-network claim. For family OOPM, if family in-network OOP accumulation prior to claim is already >= $14000, then member responsibility is 0 for in-network claim (for any member). If not, we compute member responsibility, then add to accumulators, but ensure that the member's OOP doesn't exceed individual OOPM, and family OOP doesn't exceed family OOPM. Usually, the member responsibility would be reduced so that the OOPM is exactly met. So we'll need to cap.

Similarly, for out-of-network claims, there is no family OOPM, but individual OOPM $14000. If member's out_of_network_oop prior >= $14000, then member responsibility 0.

Now, deductible application: for in-network claim, check family deductible balance. Since aggregate, coinsurance begins only when total family deductible credits reach $6400. So before the claim, if family_deductible_balance < 6400, then we can apply deductible up to (6400 - family_deductible_balance). The deductible_applied is the lesser of that remaining and the allowed amount. That amount goes to the member's deductible balance and family deductible balance. Then if any allowed amount remains, coinsurance 10% applies to the remainder. If family_deductible_balance >= 6400, then deductible_applied = 0, and entire allowed amount subject to 10% coinsurance.

For out-of-network claim: we look at the member's individual deductible balance (which is the same single balance). The threshold is $6400 (the out-of-network deductible). If member's deductible balance < 6400, then deductible_applied = min(allowed amount, 6400 - member_deductible_balance). That amount is added to member's deductible balance and family deductible balance. Then any remaining allowed amount is subject to 40% coinsurance. If member's deductible balance >= 6400, then deductible_applied = 0, and entire allowed amount at 40% coinsurance.

Then, member responsibility = deductible_applied + coinsurance_amount (capped by OOPM). For out-of-network, coinsurance_amount = (allowed - deductible_applied) * 0.40, if any remains.

Now, need to process each line. After processing all lines, we need to report final components for Claims 7 (voided), 14, 18. For claim 7: it's voided, so all components should be 0.00. For claim 14, we need to give its final adjudication after adjustment? It is not adjusted, so it's as originally processed at Line 14. For claim 18, as processed at Line 18. Also need ending accumulators for each member and family after processing all lines (i.e., after Line 18). So we must correctly simulate all lines, including adjustments and voids.

Let's list the lines with their processing order. We'll keep running accumulators. I'll maintain for each member: ded_bal (total deductible applied), in_oop (in-network OOP accumulation), out_oop (out-of-network OOP accumulation). Also family_ded_bal = sum of ded_bal for all members. family_in_oop = sum of in_oop for all members. Also need to track each claim's member responsibility, plan paid, deductible_applied, copay_amount (always 0), coinsurance_amount for claims we need to report.

We'll process lines sequentially, with adjustments and void at their position. We need to record the claim data for later reference because adjustments reference claim numbers. So I'll store claims in a dictionary with key claim number: {member, allowed, network, deductible_applied, coinsurance, member_resp, plan_paid, ...}. For void, we'll note that claim is voided and its accumulators removed at that point. For adjustment, we'll remove the old claim's credits, then re-adjudicate with new allowed amount, using accumulators as they stand at adjustment time.

Let's go line by line.

Initialize:
Member A, B, C, D:
  ded = 0
  in_oop = 0
  out_oop = 0
family_ded = 0
family_in_oop = 0

Line 1 — Claim 1 — 2026-01-14 — B (spouse) In-network, allowed 4445.54.

Family_ded before = 0 < 6400. Remainder = 6400 - 0 = 6400. Deductible_applied = min(4445.54, 6400) = 4445.54.
Allowed after ded = 4445.54 - 4445.54 = 0. So coinsurance = 0.
Member responsibility = deductible = 4445.54. This is in-network, so add to in_oop.
Check OOPM: B's in_oop prior = 0, so no cap needed. Family in_oop prior = 0, after adding 4445.54, family in_oop = 4445.54, which is < 14000, so no cap.
Plan_paid = allowed - member_resp = 4445.54 - 4445.54 = 0.
Update accumulators:
  B.ded += 4445.54 = 4445.54
  B.in_oop += 4445.54 = 4445.54
  family_ded = 4445.54
  family_in_oop = 4445.54
Store claim 1.

Line 2 — Claim 2 — 2026-01-20 — B (spouse) In-network, allowed 2230.92.
Family_ded before = 4445.54 < 6400, remainder = 6400 - 4445.54 = 1954.46.
Deductible_applied = min(2230.92, 1954.46) = 1954.46.
Remaining allowed = 2230.92 - 1954.46 = 276.46. Coinsurance = 10% of 276.46 = 27.646 → round to 27.65 (half up: 27.646 → 27.65? Actually, 27.646, the third decimal is 6, so round up: 27.65). Member responsibility = 1954.46 + 27.65 = 1982.11.
Now check OOPM: B's in_oop prior = 4445.54, after adding 1982.11 would be 6427.65, which exceeds individual in-network OOPM $7000? No, 6427.65 < 7000. So no individual cap. Family in_oop prior = 4445.54, after = 4445.54 + 1982.11 = 6427.65, < 14000. So no cap.
Plan_paid = 2230.92 - 1982.11 = 248.81? Let's compute: plan_paid = coinsurance portion * 0.90 = 276.46 * 0.90 = 248.814 → 248.81. So yes. Or plan_paid = allowed - member_resp = 2230.92 - 1982.11 = 248.81. Good.
Update:
  B.ded += 1954.46 → now B.ded = 4445.54 + 1954.46 = 6400.00
  B.in_oop += 1982.11 → 4445.54 + 1982.11 = 6427.65
  family_ded += 1954.46 → 4445.54 + 1954.46 = 6400.00 (exactly at family deductible)
  family_in_oop += 1982.11 → 4445.54 + 1982.11 = 6427.65
So after Line 2, family deductible is met (6400.00). So for future in-network claims, no deductible, only coinsurance 10%.

Line 3 — Claim 3 — 2026-02-03 — A, In-network, allowed 6842.97.
Before claim, family_ded = 6400 > 6400? Actually equal to 6400, so deductible met (>=). So deductible_applied = 0.
Entire allowed subject to 10% coinsurance. Coinsurance = 6842.97 * 0.10 = 684.297 → 684.30.
Member responsibility = 684.30 (in-network, so in_oop).
Check OOPM: A's in_oop prior = 0, after adding 684.30, still 684.30 < 7000, ok. Family in_oop prior = 6427.65, after = 6427.65 + 684.30 = 7111.95, which is still < 14000, so no cap.
Plan_paid = 6842.97 - 684.30 = 6158.67.
Update:
  A.ded unchanged = 0 (but A still has ded balance 0, but no deductible applied here)
  A.in_oop = 684.30
  family_ded unchanged (6400)
  family_in_oop = 7111.95
Store claim 3.

Line 4 — Claim 4 — 2026-02-16 — C, Out-of-network, allowed 22929.00.
This is out-of-network. Use member C's deductible balance. C.ded prior = 0. OON deductible threshold = 6400.
Check if C.ded < 6400: yes, 0 < 6400, so deductible applies. Remaining to meet OON deductible: 6400 - 0 = 6400.
Deductible_applied = min(22929.00, 6400) = 6400.00.
Remaining allowed = 22929.00 - 6400.00 = 16529.00.
Coinsurance = 40% of 16529.00 = 6611.60. (16529 * 0.4 = 6611.60 exactly? 16529 * 0.4 = 6611.6 → 6611.60).
Member responsibility = deductible (6400) + coinsurance (6611.60) = 13011.60. This is OON, so goes to out_of_network_oop for C.
Check OOPM: OON individual OOPM is $14000. C's out_oop prior = 0, after adding 13011.60 = 13011.60, which is less than 14000, so no cap. No family OOPM for OON, so ignore.
Plan_paid = allowed - member_resp = 22929.00 - 13011.60 = 9917.40? Actually plan pays 60% of remaining after deductible: 16529 * 0.60 = 9917.40. Yes.
Update accumulators:
  C.ded += 6400 → C.ded = 6400
  C.out_oop += 13011.60 → C.out_oop = 13011.60
  family_ded += 6400 → family_ded = 6400 + 6400 = 12800. (family deductible balance now 12800, exceeding in-network family threshold but it's just a running total.)
  family_in_oop unchanged (7111.95) because OON cost sharing doesn't count to family in-network OOPM. So family_in_oop remains 7111.95.
Store claim 4.

Line 5 — Claim 5 — 2026-02-25 — A, In-network, allowed 19.56.
Family deductible already met (family_ded = 12800 >= 6400), so deductible_applied = 0.
Coinsurance 10% of 19.56 = 1.956 → 1.96.
Member responsibility = 1.96 (in-network, in_oop).
Check A's in_oop prior = 684.30, after adding 1.96 = 686.26 < 7000. Family in_oop prior = 7111.95, after = 7113.91 < 14000.
Plan_paid = 19.56 - 1.96 = 17.60.
Update:

Line 9 — ADJUSTMENT to Claim 3 — 2026-04-08 — A
This is an adjustment of claim 3. We need to undo claim 3's credits from accumulators as they stand now, then re-adjudicate using corrected allowed amount 5816.52 against current accumulators (which now have all claims through Line 8 processed).
So first, retrieve original claim 3 data: we had allowed 6842.97, deductible_applied = 0, coinsurance = 684.30, member_resp = 684.30, plan_paid = 6158.67. Also note that claim 3 was for A, in-network. So we need to remove its impact:
  - A.in_oop originally added 684.30, so we subtract 684.30 from A.in_oop.
  - family_in_oop originally added 684.30, so subtract 684.30 from family_in_oop.
  - It had no deductible_applied, so no change to A.ded or family_ded.
  - Then re-adjudicate with new allowed 5816.52 against current accumulators after removal. After removal, accumulators before re-adjudication should be as if claim 3 never happened, but with all later claims up to line 8 still in effect. So we need to compute the state just before Line 9 adjustment, but with claim 3 removed. So let's compute the state after Line 8 but before Line 9, then remove claim 3.
State after Line 8 (end of Line 8 processing):
  A.ded = 0
  A.in_oop = 2412.33 (from lines 3,5,7: claim3 gave 684.30, claim5 1.96, claim7 1726.07 = 2412.33)
  A.out_oop = 0
  B.ded = 6400
  B.in_oo

We need to process each line in the ledger in order, updating accumulators for each member and the family. The plan is aggregate deductible: family deductible $6400, no individual deductible, so for in-network services, deductible must be satisfied at the family level before any coinsurance. For out-of-network, individual deductible is $6400, measured against the member's single deductible balance, but the plan says "In-network and out-of-network deductible credits accumulate to a SINGLE member deductible balance." So the deductible balance is per member? Wait, clarify: "In-network and out-of-network deductible credits accumulate to a SINGLE member deductible balance. The amount above is the threshold that balance is measured against when the service is out-of-network." That is ambiguous. The plan document says: "Deductible: Individual (in-network) 3200.00; Family (in-network) 6400.00; Structure: AGGREGATE — the plan pays no coinsurance for any member until total family credits reach the family deductible amount. There is no individual deductible under this structure. Out-of-network (individual) 6400.00. In-network and out-of-network deductible credits accumulate to a SINGLE member deductible balance. The amount above is the threshold that balance is measured against when the service is out-of-network."

Interpretation: The deductible is aggregate for in-network, meaning the family deductible is the threshold for in-network services. But there is also an out-of-network individual deductible of $6400, which is measured against "the member's single deductible balance," which is the same balance that accumulates both in-network and out-of-network credits. So each member has a deductible balance, and family has a deductible balance? The aggregate structure means that for in-network, the plan pays no coinsurance until total family credits reach the family deductible ($6400). So the family deductible balance is what matters for in-network services. The individual balance is also tracked, but for in-network, the applicable threshold is the family deductible, not the individual. For out-of-network, the applicable threshold is the out-of-network individual deductible ($6400), measured against the member's individual balance. The family balance still accumulates out-of-network credits? The addendum says: "Out-of-network claims are measured against the out-of-network individual thresholds only; the family amounts, which are in-network amounts, do not limit an out-of-network claim. The credits an out-of-network claim generates still accumulate to the member's balance and to the family balance." So out-of-network deductibles are applied based on the member's individual balance vs the OON individual deductible. The family balance also accumulates the deductible_applied from OON claims.

So we need to track:
- For each member: deductible balance (the sum of all deductible_applied amounts from all their claims, both in and out-of-network). This is the "single member deductible balance."
- Family deductible balance: sum of all deductible_applied from all members' claims (both in and out-of-network).
- For OOPM: Individual in-network OOPM = $7000; individual OON OOPM = $14000; family in-network OOPM = $14000. The OOPM accumulation is member_responsibility for each claim. The plan says: "Once a member reaches the out-of-pocket maximum the plan pays 100% of the allowed amount for covered services for the remainder of the plan year." The OOPM is per individual, but the family OOPM is $14000. The plan doesn't specify whether it's aggregate or embedded for OOPM. Typically, under an HDHP, the family OOPM is aggregate as well? The plan document says "Family (in-network) ... 14000.00" and "Individual (out-of-network) ... 14000.00". It doesn't specify structure for OOPM. But the addendum says: "A balance is the running total of deductible_applied (for a deductible) or of member_responsibility (for an out-of-pocket balance)." So we track each member's OOP balance and family OOP balance. The family OOP maximum is $14000; once any member reaches the individual OOPM? The plan document: "Once a member reaches the out-of-pocket maximum the plan pays 100% of the allowed amount for covered services for the remainder of the plan year." That seems per member. But there is a family OOPM, which might cap total family out-of-pocket. Under typical HDHP rules, there is an aggregate family OOPM: once the family's total OOP reaches $14000, all members are covered at 100% for the rest of the year. The plan doesn't specify embedded vs aggregate for OOPM. Since it says "Once a member reaches the out-of-pocket maximum", it implies individual OOPM applies (i.e., each member has their own $7000 in-network OOPM, and $14000 OON). The family OOPM of $14000 is likely the maximum total family out-of-pocket, after which all members are covered at 100%. But the plan doesn't explicitly say if the family OOPM is aggregate or embedded. The addendum doesn't clarify. I'll assume standard: individual OOPM is per member, and family OOPM is the cap on total family OOP. So we track each member's OOP balance and family OOP balance. For in-network services, the member's OOP balance is compared to the individual in-network OOPM ($7000) and the family OOP balance to the family OOPM ($14000). For out-of-network, the member's OOP balance is compared to the individual OON OOPM ($14000), and the family OOP balance to the family OOPM ($14000). However, the plan says "Individual (out-of-network) ... 14000.00" as the OOPM. So OON OOPM is $14000. The family OOPM is $14000. So if a member hits $14000, they are covered at 100% even for OON? Or is the family OOPM only for in-network? The plan says "Out-of-pocket maximum: Individual (in-network) 7000.00; Family (in-network) 14000.00; Individual (out-of-network) 14000.00". So the family OOPM is listed under in-network, but presumably it's the overall family OOPM. The OON OOPM is individual only. So the family OOPM of $14000 likely applies to all covered services, but the individual OON OOPM is $14000 as well. So if a member's OOP balance hits $14000, they are covered at 100% for all services. The family OOPM of $14000 is the maximum total family OOP; once the family balance hits $14000, all members are covered at 100%. So we need to apply both: if individual OOP balance reaches the applicable OOPM (in-network $7000 for in-network services, OON $14000 for OON services), then that member's cost share is 0% for that service (and subsequent). Also, if family OOP balance reaches $14000, all members covered 100%. But the plan says "Once a member reaches the out-of-pocket maximum the plan pays 100% of the allowed amount for covered services for the remainder of the plan year." That suggests it's per member and the OOPM is the individual one. But it also lists family OOPM. So likely the family OOPM is an aggregate cap that overrides. In many HDHPs, the family OOPM is aggregate, meaning once the family's total OOP reaches the family OOPM, the plan pays 100% for all family members. The individual OOPM is embedded, so each member has their own individual OOPM, but the family OOPM cannot be exceeded. I'll assume that: For each service, we check if the member has already reached their applicable OOPM (in-network: $7000, out-of-network: $14000) before the claim. If so, then member responsibility = 0 (plan pays 100%). Also, after the claim, if the family OOP balance reaches $14000, then subsequent claims for all members are covered at 100% as well. But the plan doesn't specify if the family OOPM is aggregate or embedded. The addendum says: "A balance is the running total ... of member_responsibility (for an out-of-pocket balance)." So we track family OOP balance as the sum of member_responsibility across all family members. The family OOPM is $14000. So if that sum reaches $14000, then all members are covered at 100% for the rest of the year. That is typical aggregate OOPM. And the individual OOPM is per member, but the family OOPM is the ultimate cap. So for each claim, we compute member responsibility based on deductible and coinsurance, then check if the member's individual OOP balance (before the claim) has already reached the individual OOPM for the network type. If yes, responsibility = 0. Then add the responsibility to individual and family OOP balances. Then check if the family OOP balance reaches $14000 after this claim; if so, future claims have 0% responsibility. But the instructions say: "Once a member reaches the out-of-pocket maximum the plan pays 100% of the allowed amount for covered services for the remainder of the plan year." So it's member-specific. The family OOPM is another threshold. I'll treat it as: if the member's individual OOP balance (after the claim) reaches the individual OOPM, then future claims for that member are 100% paid. If the family OOP balance reaches $14000, all members are covered at 100% even if their individual OOPM hasn't been reached. That's typical.

Now, we need to process the ledger from the given starting accumulators: as of before Line 1. So initial accumulators:

A: deductible balance 1729.94, OOP balance 1762.13
B: deductible 0.00, OOP 0.00
C: deductible 1382.40, OOP 1945.98
Family: deductible 3112.34, OOP 3708.11

We need to apply each line, updating these balances. The family deductible threshold is 6400 (aggregate). The family OOPM threshold is 14000. The individual OOPM in-network is 7000, out-of-network 14000. The individual deductible threshold for in-network is not used (since aggregate), but for out-of-network, the individual deductible threshold is 6400, measured against the member's individual deductible balance. The plan says "In-network and out-of-network deductible credits accumulate to a SINGLE member deductible balance." So each member's deductible balance is used for OON deductible threshold. For in-network, the deductible applied is determined by the family deductible balance relative to the family deductible threshold of 6400. But the addendum says: "A claim's deductible_applied is the LESSER of its allowed amount and the room left under the deductible threshold that applies to it: in-network: the smaller of the member's individual remainder and the family remainder (embedded), or the family remainder alone (aggregate)." So for aggregate, deductible_applied for in-network is the lesser of allowed amount and the remaining family deductible amount (i.e., family threshold minus current family deductible balance). There is no individual deductible for in-network. So for in-network claims, deductible_applied = min(allowed, max(0, 6400 - family_deductible_balance_before)). For out-of-network, deductible_applied = min(allowed, max(0, 6400 - member_deductible_balance_before)), because the threshold is the out-of-network individual deductible of 6400, and it's measured against the member's balance. However, note that the member's deductible balance includes all credits (in and out). So if the member's balance is less than 6400, they have room. But the family deductible balance is also affected by out-of-network claims, so the family deductible balance will also accumulate those credits. But the threshold for OON is the individual 6400, not the family. So the member could have a deductible balance of 0, but the family deductible might be near 6400; that doesn't affect OON claims. So correct.

For OOPM, we need to check individual OOPM thresholds. For in-network claims, the member's individual OOP balance before the claim is compared to the in-network OOPM of 7000. If balance >= 7000, then member responsibility = 0, plan pays 100%. For out-of-network claims, the member's OOP balance before the claim is compared to the OON OOPM of 14000. If >= 14000, then 0. Also, after the claim, if the family OOP balance reaches 14000, all future claims are 100% covered? The plan says "Once a member reaches the out-of-pocket maximum the plan pays 100%...". It doesn't explicitly say that the family OOPM triggers 100% for all members, but it's standard. The family OOPM is listed, so I'll assume it works as aggregate: if family OOP balance >= 14000, then all members are covered 100% from that point on. But careful: The family OOPM is under "in-network" perhaps? The family OOPM is $14000 and individual in-network is $7000, individual OON is $14000. So family OOPM is $14000, which is the same as OON individual. It's likely that once the family OOP balance reaches $14000, no further cost sharing. I'll apply that: if family OOP balance before the claim >= 14000, then member responsibility = 0 for all future claims, regardless of individual OOPM. But note that the individual OOPM might be reached earlier. So the logic: For each claim, compute the normal cost sharing (deductible + coinsurance). Then apply OOPM limits: if the member's OOP balance before the claim is already >= the applicable individual OOPM (based on network), then responsibility = 0. Also, if the family OOP balance before the claim is >= 14000, then responsibility = 0. But the plan document says "Once a member reaches the out-of-pocket maximum the plan pays 100% of the allowed amount for covered services for the remainder of the plan year." So it's member-specific. The family OOPM is the maximum out-of-pocket for the family; if the family reaches it, no member pays more. So I'll treat it as: Before adjudicating a claim, check if the member's individual OOP balance >= the applicable OOPM (7000 for in-network, 14000 for out-of-network). If yes, cost share = 0. Then, regardless, after adding the member responsibility to the family OOP balance, if the family OOP balance becomes >= 14000, then future claims will have 0 cost share. But the family OOPM cap might also apply to the current claim: if the family OOP balance before the claim is already >= 14000, then the member's responsibility is 0 even if the individual hasn't hit. That is typical. The plan document isn't explicit, but given the family OOPM is listed, I'll assume it acts as a cap: the family cannot pay more than $14000 in total. So if family OOP balance before claim >= 14000, then all members have 0 cost share. I'll implement that.

Also, the plan says "Preventive care: In-network preventive services required to be covered without cost share are paid at 100%...". So if a claim is preventive and in-network, no cost share, no deductible accumulation. Out-of-network preventive is subject to OON deductible and coinsurance. So we need to identify preventive services. In the ledger, Line 5: C (child) Annual wellness visit, out-of-network. That is preventive. So OON preventive is subject to OON deductible and coinsurance. That's fine.

Now, we need to process lines 1-20, with adjustments and voids. We'll keep track of the accumulators after each line. We'll need to record the final components for Claim 6 (which is adjusted by Line 16), Claim 15, Claim 20. Claim 6 originally was Line 6, then adjusted at Line 16. So we need to compute the re-adjudicated components at the time of the adjustment (Line 16) using the accumulators as they stand at that point, after unwinding the original claim's credits. The instructions: "ADJUSTMENT. When a line is an adjustment to an earlier claim, the credits that claim generated — its deductible credit and its member responsibility — are removed from every accumulator they touched (the member's and the family's), and the claim is adjudicated again at its corrected values against the accumulators AS THEY STAND at the point the adjustment is processed." So we need to first process the original claim at its original time, then later, when we get to the adjustment line, we remove the original credits from the accumulators as they currently stand (i.e., after all intervening claims), then re-adjudicate with the corrected allowed amount and billed charge. That means the final components for Claim 6 are the ones from the adjustment.

Similarly, Claim 1 is voided at Line 11, so we remove its credits and post nothing. So Claim 1 is effectively gone, and any claims after that are not affected except that accumulators are reduced.

So we need to simulate the ledger step by step. We'll maintain the following accumulators for each member and family:

For each member: deductible_balance (float), oop_balance (float)
Family: family_deductible_balance (float), family_oop_balance (float)

We'll also need to track the original claim's contributions so we can unwind them later. For each claim, we need to store the deductible_applied amount and the member_responsibility amount, because those are the credits that affect the accumulator balances. We'll need to be able to subtract them when adjusting/voiding. So we can keep a dictionary mapping claim numbers to their original credits (deductible_applied, member_responsibility, and which member it belongs to). When we get to an adjustment/void, we look up the original credits, subtract them from the member's deductible and OOP, and from the family's deductible and OOP, then re-adjudicate for adjustment.

Now, the initial balances are given. We'll process line by line:

Line 1: Claim 1, A, in-network PT, allowed 1553.18. Family deductible threshold 6400, current family deductible balance 3112.34. Remaining family deductible = 6400 - 3112.34 = 3287.66. Deductible_applied = min(1553.18, 3287.66) = 1553.18. So all goes to deductible. Then after deductible, no coinsurance because deductible not yet met? Actually, after applying deductible, the remaining allowed amount is 0, so no coinsurance. Member responsibility = deductible_applied + coinsurance = 1553.18 + 0 = 1553.18. Check OOPM: A's individual OOP balance before: 1762.13. In-network OOPM is 7000, so he hasn't hit it. Family OOP balance before: 3708.11, not at 14000. So no reduction. So member responsibility = 1553.18. Plan paid = allowed - member responsibility = 1553.18 - 1553.18 = 0? Actually plan paid = allowed - member responsibility = 0. So plan paid = 0.00. Then update accumulators: A deductible_balance += 1553.18 => 1729.94+1553.18 = 3283.12. A OOP balance += 1553.18 => 1762.13+1553.18 = 3315.31. Family deductible_balance += 1553.18 => 3112.34+1553.18 = 4665.52. Family OOP balance += 1553.18 => 3708.11+1553.18 = 5261.29.

Store Claim 1: member A, deductible_applied=1553.18, member_responsibility=1553.18.

Line 2: Claim 2, A, in-network inpatient, allowed 21710.91. Family deductible balance before: 4665.52. Remaining family deductible: 6400 - 4665.52 = 1734.48. Deductible_applied = min(21710.91, 1734.48) = 1734.48. After that, remaining allowed = 21710.91 - 1734.48 = 19976.43. Coinsurance is 10% member, so member coinsurance = 19976.43 * 0.10 = 1997.643, round to 1997.64. Member responsibility = 1734.48 + 1997.64 = 3732.12. Check OOPM: A OOP balance 3315.31, not at 7000. So no cap. Plan paid = allowed - member responsibility = 21710.91 - 3732.12 = 17978.79. Update: A deductible balance += 1734.48 => 3283.12+1734.48 = 5017.60. A OOP balance += 3732.12 => 3315.31+3732.12 = 7047.43. Now A OOP balance exceeds 7000 (in-network OOPM). So future in-network claims for A will have 0 member responsibility? But note: the OOPM cap is reached after this claim, so for subsequent claims, A's cost share will be 0. Family deductible balance += 1734.48 => 4665.52+1734.48 = 6400.00 exactly. Family OOP balance += 3732.12 => 5261.29+3732.12 = 8993.41.

Store Claim 2: A, deductible_applied=1734.48, member_responsibility=3732.12.

Line 3: Claim 3, C, in-network outpatient infusion, allowed 454.13. Family deductible balance before: 6400.00 (already met). So remaining family deductible = 0. Deductible_applied = 0. Coinsurance: 10% member = 454.13 * 0.10 = 45.413, round 45.41. Member responsibility = 45.41. Check OOPM: C's OOP balance before: 1945.98. In-network OOPM is 7000, so not hit. So no cap. Plan paid = 454.13 - 45.41 = 408.72. Update: C deductible_balance += 0 => stays 1382.40. C OOP balance += 45.41 => 1945.98+4

We need to process the ledger in order, updating accumulators step by step. Starting balances given:

A: deductible 60.69, OOP 60.69
B: deductible 383.93, OOP 924.55
C: deductible 1524.34, OOP 2116.83
Family total: deductible 1968.96, OOP 3102.07

Plan details: Embedded deductible in-network: individual 2500, family 5000. OOP in-network: individual 5500, family 11000. Out-of-network deductible: 5000 individual, OOP 11000 individual. Copays credit deductible and OOP. Coinsurance after deductible: in-network 30% member, out-of-network 50% member. Copays: primary care 25, specialist 50, urgent care 60, ER 300, generic pharmacy 10. Preventive in-network no cost, out-of-network preventive subject to deductible and coinsurance? The plan says: "Preventive care: In-network preventive services required to be covered without cost share are paid at 100% of the allowed amount and are not subject to the deductible, coinsurance, or a copay." Out-of-network preventive: not mentioned, so likely subject to normal out-of-network benefits (deductible and coinsurance). The glossary says: "Preventive services in-network carry no cost share and move no accumulator. An out-of-network preventive service is subject to the out-of-network deductible and coinsurance." So yes, out-of-network preventive is subject to deductible and coinsurance.

Now process each line.

Line 1: Claim 1, C, in-network, inpatient admission with surgery. Not a preventive service, so subject to deductible and coinsurance. No copay mentioned; it's an inpatient admission, coinsurance after deductible. We need to compute deductible applied, member responsibility, plan paid, and update accumulators.

Current accumulators: C deductible balance = 1524.34, family deductible balance = 1968.96. In-network, so embedded: individual deductible for C is 2500, remaining = 2500 - 1524.34 = 975.66. Family deductible remaining = 5000 - 1968.96 = 3031.04. The applicable deductible threshold is the smaller of individual and family remainder: min(975.66, 3031.04) = 975.66. So C can apply up to that much deductible. Allowed amount = 10074.70. Deductible applied = min(10074.70, 975.66) = 975.66. Then after that, remaining allowed amount = 10074.70 - 975.66 = 9099.04. Coinsurance: 30% member = 0.30 * 9099.04 = 2729.712 -> round to 2729.71. Total member responsibility = deductible applied + coinsurance = 975.66 + 2729.71 = 3705.37. Plan paid = allowed - member = 10074.70 - 3705.37 = 6369.33. Check OOP: member responsibility 3705.37 adds to C's OOP and family OOP. C's OOP goes from 2116.83 to 2116.83 + 3705.37 = 5822.20. OOP max for C in-network is 5500. But note: once OOP max reached, no further cost. But for this claim, we compute cost share based on accumulators before claim. C's OOP balance before claim is 2116.83, which is less than 5500. So we apply the cost share. The member responsibility of 3705.37 will push C's OOP over 5500. But that's fine; the claim is processed fully. Post-claim, C's OOP becomes 5822.20. However, for future claims, if C has already reached OOP max, then no cost share. But we'll see. Also, deductible credits: C's deductible balance becomes 1524.34 + 975.66 = 2500.00 (exactly individual limit). Family deductible balance becomes 1968.96 + 975.66 = 2944.62. OOP updates: C OOP = 5822.20, family OOP = 3102.07 + 3705.37 = 6807.44.

Now we need to check if C's OOP has reached the in-network individual OOP max (5500). After this claim, C's OOP is 5822.20 > 5500, so future in-network claims for C will have no member cost, and plan pays 100%. Out-of-network claims still subject to out-of-network OOP of 11000. So for future in-network claims for C, no cost share. But note: The OOP max applies to in-network covered services. For out-of-network, the OOP max is higher (11000). So C's OOP balance is 5822.20, which is above 5500 in-network, so in-network claims will be free. But out-of-network claims will still be subject to cost share until OOP reaches 11000. However, the plan document says: "Once a member reaches the out-of-pocket maximum the plan pays 100% of the allowed amount for covered services for the remainder of the plan year." It doesn't distinguish in vs out-of-network for the OOP max? The OOP max is listed: Individual (in-network) 5500, Individual (out-of-network) 11000. So there are two separate OOP accumulators? The document says: "In-network and out-of-network deductible credits accumulate to a SINGLE member deductible balance." But for OOP, it says: "Out-of-pocket maximum Individual (in-network) ................ 5500.00 Family (in-network) .................... 11000.00 Individual (out-of-network) ............ 11000.00". It doesn't explicitly say whether they are separate accumulators. Usually, in-network and out-of-network OOP are separate, but the plan might have combined? The accumulator addendum says: "A balance is the running total of deductible_applied (for a deductible) or of member_responsibility (for an out-of-pocket balance). Because the out-of-network thresholds are higher, out-of-network claims can carry a member's balance past the in-network individual amount, and the family balances past the family amounts; the balances are not capped at the in-network amounts." This implies that the OOP balance is a single running total of member responsibility (both in-network and out-of-network). Then, for in-network services, the plan pays 100% once that balance reaches the in-network OOP max (5500). For out-of-network, once the balance reaches the out-of-network OOP max (11000), the plan pays 100% of allowed amount for out-of-network covered services. So the same OOP balance is used for both, but the thresholds are different. So after Line 1, C's OOP balance is 5822.20, which exceeds 5500. So for any in-network claim for C after this, member cost share = 0 (plan pays 100% of allowed for in-network). For out-of-network claims, C's OOP balance is 5822.20, which is less than 11000, so still subject to deductible and coinsurance for out-of-network.

Important: For in-network claims, once the individual OOP max is reached, no further cost share. So from this point onward, C's in-network claims will be 0 member responsibility, and no deductible applied (since OOP max met, plan pays 100%). The plan document says: "Once a member reaches the out-of-pocket maximum the plan pays 100% of the allowed amount for covered services for the remainder of the plan year." It doesn't restrict to in-network. So if a member reaches OOP max, then for any covered service (in or out of network?) The OOP max is different for in and out. The phrasing "Once a member reaches the out-of-pocket maximum" – which maximum? It likely refers to the applicable OOP max for the type of service. The document then lists the thresholds. I think it's standard: once the in-network OOP max is reached, in-network services are 100% paid; once the out-of-network OOP max is reached, out-of-network services are 100% paid. So C's in-network OOP max is met, so in-network claims will be free. But out-of-network still subject to cost share until OOP balance reaches 11000. That's consistent with the accumulator note: "out-of-network claims can carry a member's balance past the in-network individual amount". So C's balance is allowed to exceed 5500, and out-of-network claims will continue to accumulate until 11000.

So after Line 1, C's accumulators: deductible 2500.00 (individual satisfied), OOP 5822.20. Family deductible 2944.62, family OOP 6807.44.

Line 2: Claim 2, A (subscriber), in-network, Specialty pharmacy administration. Not a typical office visit, so no copay assumed; it's likely subject to deductible and coinsurance (like a medical service). We'll treat as a service subject to deductible/coinsurance. Allowed amount 4603.57. A's accumulators: deductible 60.69, OOP 60.69. Individual deductible remaining: 2500 - 60.69 = 2439.31. Family deductible remaining: 5000 - 2944.62 = 2055.38. Embedded: applicable deductible left = min(2439.31, 2055.38) = 2055.38. So deductible applied = min(4603.57, 2055.38) = 2055.38. After that, remaining allowed = 4603.57 - 2055.38 = 2548.19. Coinsurance 30% member = 0.30 * 2548.19 = 764.457 -> 764.46. Total member = 2055.38 + 764.46 = 2819.84. Plan paid = 4603.57 - 2819.84 = 1783.73. Now update: A deductible balance becomes 60.69 + 2055.38 = 2116.07. A OOP balance becomes 60.69 + 2819.84 = 2880.53. Family deductible: 2944.62 + 2055.38 = 5000.00 (exactly). Family OOP: 6807.44 + 2819.84 = 9627.28. A's in-network OOP max is 5500, not yet reached (2880.53). So no cap.

Line 3: Claim 3, B (spouse), in-network, Specialist office visit. Copay: specialist office visit copay is $50. Copay credits deductible and OOP. Allowed amount 339.69. Copay is a flat amount, not based on allowed. For copay services, the member pays the copay (unless deductible applies? The plan says copay, but also says "Copays DO credit the deductible." So we need to determine if the copay is the only cost share, or if deductible/coinsurance apply as well. Typically, for office visits, the copay is the cost share, and the plan pays the rest. The plan document says: "Primary care office visit ........................ 25.00 copay Specialist office visit .......................... 50.00 copay Urgent care ...................................... 60.00 copay Emergency room ................................... 300.00 copay, WAIVED if the visit results in an inpatient admission, in which case the visit is subject to the deductible and coinsurance Generic retail pharmacy .......................... 10.00 copay Copays DO credit the deductible. Copays always credit the out-of-pocket maximum." There is no mention that these copay services are subject to deductible or coinsurance. So presumably, the copay is the total member cost for that service, and the plan pays the rest. So for a specialist office visit, member pays $50 copay, plan pays (allowed - copay) = 339.69 - 50 = 289.69. The copay credits deductible and OOP. But note: if the deductible has not been met, does the copay count toward deductible? The plan says "Copays DO credit the deductible." So they add to the deductible balance. But does the member still have to pay deductible before the copay? No, copay is a fixed amount, not dependent on deductible. The phrase "Copays DO credit the deductible" means that the amount of the copay is added to the deductible accumulator, as if it were a deductible payment. But the member still only pays the copay. So for this claim, B's member responsibility = 50.00 (copay). deductible_applied = 50.00 (since copay credits deductible). coinsurance = 0, copay = 50.00. Now, check if B's deductible is already met? B's current deductible balance: 383.93. Individual deductible 2500, remaining = 2500 - 383.93 = 2116.07. Family deductible remaining: after line 2, family deductible is 5000.00 (exactly met). So family deductible is satisfied. Embedded: because family deductible is met, the applicable deductible is satisfied (the family amount is met, so no further deductible for any member). The rule: "under an embedded structure a member's deductible is satisfied by the lesser of their individual remainder and the family remainder. Under an aggregate structure no member reaches coinsurance until the family amount is met." Since family deductible is now 5000.00, the family remainder is 0. So for any in-network claim, the applicable deductible remainder is 0. So deductible_applied = 0. But the copay still credits deductible? The plan says "Copays DO credit the deductible." So even if the deductible is met, the copay will add to the deductible balance, but since the deductible is already met, it doesn't affect cost sharing. The deductible_applied for a claim is the amount that counts toward meeting the deductible, but if the deductible is already met, deductible_applied = 0 (since no room left). So for this claim, allowed amount 339.69, copay 50. Member responsibility = 50.00. Plan paid = 289.69. Deductible_applied = 0. Coinsurance = 0. So B's deductible balance remains 383.93 (no increase because deductible already met? Actually, the copay credit would increase the balance, but the balance is capped? The plan doesn't say deductible balance is capped at the threshold. The accumulator addendum: "A balance is the running total of deductible_applied." So deductible_applied is the amount applied toward the deductible, and we add it to the balance. For a claim, deductible_applied is the lesser of allowed amount and the room left. Since room left is 0, deductible_applied = 0. So B's deductible balance doesn't change. So B's deductible remains 383.93. B's OOP: member responsibility 50.00, so B's OOP becomes 924.55 + 50 = 974.55. Family OOP becomes 9627.28 + 50 = 9677.28. Family deductible stays 5000.00. So no change in deductible.

Line 4: Claim 4, B (spouse), out-of-network, Inpatient admission. Allowed amount 15484.21. Out-of-network: deductible 5000 individual, coinsurance 50% member after deductible. Out-of-network OOP max 11000. B's current deductible balance: 383.93 (from previous). Out-of-network deductible threshold is 5000, and the deductible balance is the same single balance. So remaining out-of-network deductible = 5000 - 383.93 = 4616.07. This is the amount that can be applied as deductible for this out-of-network claim. Family deductible is not relevant for out-of-network determination (family amounts are in-network). So deductible_applied = min(15484.21, 4616.07) = 4616.07. After that, remaining allowed = 15484.21 - 4616.07 = 10868.14. Coinsurance 50% member = 0.50 * 10868.14 = 5434.07. Total member responsibility = 4616.07 + 5434.07 = 10050.14. Plan paid = 15484.21 - 10050.14 = 5434.07. Now update accumulators: B's deductible balance becomes 383.93 + 4616.07 = 5000.00 (exactly out-of-network individual deductible met). B's OOP balance becomes 974.55 + 10050.14 = 11024.69. This exceeds the out-of-network OOP max of 11000? 11024.69 > 11000. So B's out-of-network OOP max is reached. Future out-of-network claims for B will have no member cost (plan pays 100% of allowed). In-network claims for B: B's OOP balance is 11024.69, which is above the in-network OOP max of 5500. So for in-network claims, B's OOP max is also met? The plan document: "Once a member reaches the out-of-pocket maximum the plan pays 100% of the allowed amount for covered services for the remainder of the plan year." Which maximum? It lists separate thresholds. Typically, if the out-of-network OOP max is higher, once the in-network OOP max is met, in-network is free; out-of-network still accumulates until its own max. The same balance is used. So B's OOP balance is 11024.69, which is greater than both 5500 and 11000. So for any covered service, in-network or out-of-network, B should have no member cost, because the balance is above the out-of-network max. However, the plan might differentiate: the in-network OOP max is 5500, so once balance reaches 5500, in-network services are 100% covered regardless of out-of-network. Since balance is 11024.69, both thresholds are exceeded. So B will have no cost share for any future claims, in or out of network. But we need to be careful: The plan says "Once a member reaches the out-of-pocket maximum" – it doesn't say "in-network" or "out-of-network". But the maximums are listed. I think the intent is that the applicable OOP max is the one for the type of service. So for in-network, it's 5500; for out-of-network, it's 11000. Since B's balance exceeds both, any service will be 100% covered. So line 4 will make B hit OOP max. However, the claim itself is processed before hitting the max, so the member pays 10050.14, which then pushes the balance over the max. So after this claim, B's OOP balance is 11024.69. Family OOP: previous 9677.28 + 10050.14 = 19727.42. Family OOP max in-network is 11000, but that's for in-network claims. The family OOP max is only for in-network? The plan lists "Family (in-network) .................... 11000.00". It doesn't list a family out-of-network OOP max. So the family OOP max is 11000 for in-network. For out-of-network, there is no family OOP max; only individual. So the family OOP balance is a running total of all member responsibilities, but it's only used to determine when the family reaches the in-network OOP max. The plan says: "Once a member reaches the out-of-pocket maximum the plan pays 100%...". That's individual. For family, there's no separate OOP max that applies across members; the family OOP max is a ceiling for the family as a whole for in-network cost sharing. The plan document: "Out-of-pocket maximum Family (in-network) .................... 11000.00". That means if the family's total in-network member responsibility reaches 11000, then all in-network services for all family members are covered at 100% for the rest of the year. But out-of-network services are not subject to the family OOP max. So the family OOP balance is relevant for in-network cost share. After line 4, family OOP is 19727.42, which far exceeds 11000. So the family in-network OOP max is met. That means for any in-network claim for any member, plan pays 100% (no member cost). But note: individual OOP max might also apply. So for in-network claims, both the individual and family OOP max are relevant. As long as either the individual's OOP balance reaches 5500 or the family OOP balance reaches 11000, the member's in-network cost share is 0. So after line 4, family OOP is 19727.42 > 11000, so all future in-network claims for all members will be 0 member responsibility. Out-of-network claims still subject to individual out-of-network OOP max (11000) and not limited by family OOP max. So we need to track both.

Now, after line 4, B's OOP balance 11024.69, family OOP 19727.42. B's deductible 5000.00 (maxed). Family deductible 5000.00 (maxed). A's accumulators: deductible 2116.07, OOP 2880.53. C's accumulators: deductible 2500.00, OOP 5822.20.

Line 5: Claim 5, B (spouse), in-network, urgent care. Copay is $60. But B's OOP balance is 11024.69, which is above in-network OOP max 5500. Also family OOP is above 11000. So no member cost. Member responsibility = 0, plan paid = allowed amount 181.01. Deductible_applied = 0, copay = 0, coinsurance = 0. Update: B's OOP remains 11024.69 (no change). Family OOP remains 19727.42. B's deductible remains 5000.00. So no change.

Line 6: Claim 6, A (subscriber), in-network, urgent care. Allowed amount 213.67. Copay is $60. A's accumulators: deductible 2116.07, OOP 2880.53. Family OOP is 19727.42 > 11000, so family OOP max is met. Therefore, no member cost for in-network claim. So member responsibility = 0, plan paid = 213.67. Copay is waived due to OOP max? Actually, copay is a cost share, so if OOP max is met, no cost share. So no copay. So claim 6: member responsibility 0, plan paid 213.67, deductible_applied 0, copay 0, coinsurance 0. This is the original adjudication before any adjustment. But later there are adjustments to Claim 6. We'll process line 6 as is now, then later adjustments will unwind and re-adjudicate. So after line 6, A's accumulators: OOP stays 2880.53 (since 0 member responsibility, no increase). A's deductible remains 2116.07. Family OOP remains 19727.42. So no change.

Line 7: Claim 7, C (child), in-network, specialist office visit. Allowed 330.22. Copay $50. Since C's in-network OOP max is met (OOP balance 5822.20 > 5500), and family OOP max is met, no member cost. So member responsibility = 0, plan paid = 330.22. No deductible applied, copay 0. Update: C's OOP remains 5822.20, family OOP remains 19727.42. So no change.

Line 8: Claim 8, C (child), out-of-network, sleep study. Allowed 1805.31. C's OOP balance 5822.20, deductible 2500.00. Out-of-network deductible threshold 5000, but C's deductible balance is 2500.00 (maxed at in-network individual). The deductible balance is single, so C's remaining out-of-network deductible = 5000 - 2500.00 = 2500.00. So deductible_applied = min

We need answer task. Need derive from reference material. Scenario: 55-year-old average-risk screening colonoscopy. During procedure polyp found and removed. Need modifier single most appropriate from list for converted service, and primary_diagnosis ICD-10-CM code reported first, given scheduled as screening.

We have selected HCPCS modifiers:
33 preventive
PT colorectal cancer screening test converted to diagnostic or other procedure. Appended when service scheduled as colorectal cancer screening becomes diagnostic or therapeutic during same encounter.
KX etc.

Scenario: scheduled as screening, polyp found removed => converted to diagnostic/therapeutic. Modifier PT. Need primary diagnosis? For screening colonoscopy converted to diagnostic due to polyp found. Coding guideline: For colorectal cancer screening colonoscopy that converts to diagnostic/therapeutic, primary diagnosis? Need think. According to coding guidelines? If a screening colonoscopy finds polyp, the primary diagnosis is polyp (e.g., K63.5 Polyp of colon) or? But there is special instructions: Medicare? For screening colonoscopy with polyp removal, primary diagnosis should be polyp? Need recall ICD-10-CM guideline: For encounters for screening colonoscopy, if a finding is found, code the finding as primary? Specifically ICD-10-CM guideline I.C.21.c.5? Screening colonoscopy? Let's recall.

ICD-10-CM Official Guidelines: Section IV? For encounters for screening, if screening is performed and a condition is found, code the condition as first-listed, with screening code as additional. However there is an exception: "A screening code may be a first-listed code if the reason for the visit is specifically the screening exam... Should a condition be discovered during the screening then the code for the condition may be assigned as an additional diagnosis." Hmm.

For colonoscopy, coding guidelines? AHA Coding Clinic? If screening colonoscopy, and polyp found, assign Z12.11 as first-listed? Actually for Medicare, if a screening colonoscopy results in polypectomy, diagnosis code for polyp? Let's recall.

The prompt asks "primary_diagnosis (the ICD-10-CM code that should be reported first for the encounter, given the encounter was scheduled as a screening)." The reference only lists HCPCS modifiers, no ICD-10 code set. We must derive. Need know code. Likely Z12.11 (encounter for screening for malignant neoplasm of colon). But when polyp found? Let's think.

Question: "given the encounter was scheduled as a screening" and "single polyp is found and removed." For a screening colonoscopy that results in polypectomy, the primary diagnosis could be polyp (K63.5) or screening Z12.11? Need answer exact.

This is a common coding issue:
- If a patient comes in for screening colonoscopy and a polyp is found and removed, the primary diagnosis is the polyp (e.g., K63.5) because the procedure is no longer just screening. But for screening colonoscopy? Some guidance says: For services that begin as screenings and become diagnostic/therapeutic, report the diagnostic indication as primary and the screening code as secondary? The modifier PT is appended to the CPT code, and primary diagnosis should be the finding (e.g., polyp). Let's investigate.

Question wording: "primary_diagnosis (the ICD-10-CM code that should be reported first for the encounter, given the encounter was scheduled as a screening)." They may want "Z12.11" because encounter scheduled as screening and primary diagnosis reflects reason for encounter? But "converted service" with modifier PT implies primary diagnosis should be the finding. Need settle.

Let's analyze from coding guidelines.

ICD-10-CM Official Guidelines for Coding and Reporting, Section IV. Diagnostic Coding and Reporting Guidelines for Outpatient Services? It states:
- For outpatient encounters for diagnostic tests that have been interpreted by a physician, the first-listed diagnosis is the condition established by the study? Hmm.

Screening guidelines: Section I.C.21? "Factors influencing health status and contact with health services" Z codes.
- For encounters for routine laboratory/radiology testing in the absence of signs/symptoms, assign Z01.89... 
- For screening codes: "Screening is the testing for disease or disease precursors in seemingly well individuals so early detection and treatment can be provided. A screening code is not necessary if the screening is inherent to a routine examination... Should a condition be discovered during the screening then the code for the condition may be assigned as an additional diagnosis." Does not specify first.
- "If the reason for the encounter is the screening, the screening code is first-listed. If the screening is performed as part of a general health examination, the screening code may be additional." Hmm.

But ICD-10 guideline I.C.21.c.5? Let's recall exact:
"Z12 Encounter for screening for malignant neoplasms: For encounters for screening for malignant neoplasms, code Z12.xx as first-listed if the reason for the visit is specifically the screening. If the screening is performed as part of a routine physical, assign Z00.00 as first-listed and Z12.xx as additional. If a malignancy is found during screening, assign the malignant neoplasm code as first-listed and Z12.xx as additional." It says if malignant neoplasm found, malignancy first. But what about benign polyp found? General guideline: "Should a condition be discovered during the screening then code for the condition may be assigned as an additional diagnosis." Not necessarily first. For screening colonoscopy with polyp, typically Z12.11 first, polyp additional? Let's recall exact for screening colonoscopy.

Let's recall AHA Coding Clinic, First Quarter 2012? "Screening colonoscopy with polypectomy" maybe: Assign Z12.11 as principal diagnosis, and K63.5 as secondary because the screening was the reason for the encounter. But for outpatient, first-listed diagnosis is the reason for encounter, which is screening. If a polyp is found, add polyp. However, with modifier PT for Medicare, diagnosis coding for colorectal cancer screening converted to diagnostic/therapeutic: The primary diagnosis should be the reason for the test? Let's recall Medicare claims processing manual, Chapter 18? Preventive and Screening Services:
For screening colonoscopy that becomes diagnostic/therapeutic: The provider should report the appropriate HCPCS code with modifier PT. The diagnosis code for the procedure should reflect the reason for the procedure? Maybe:
- If the procedure is scheduled as a screening, and during the procedure a polyp is found, the diagnosis code should be the polyp (e.g., K63.5 or D12.x) as primary, and the screening code (Z12.11) as secondary? Actually Medicare says: "When a screening colonoscopy results in the removal of tissue, the appropriate screening diagnosis code (Z12.11) should be listed as primary and the polyp code as secondary"?
Let's search memory.

This is important. Let's recall from official CMS "Colorectal Cancer Screening: Correct Coding and Billing" maybe:
- For screening colonoscopy, report HCPCS/CPT with modifier 33 for preventive services? Medicare uses G0105/G0121, no PT? 
- If during a screening colonoscopy a lesion is found and removed, the procedure is considered diagnostic/therapeutic. The diagnosis code for the procedure should be the finding (polyp). The screening diagnosis code should be secondary? The primary reason for the encounter was screening, but CPT modifier PT indicates conversion.

ICD-10 guideline for screening: "If a condition is found during a screening exam, code the condition as additional" not first. But there is nuance: if the condition found is significant and treated, maybe first? Actually for outpatient, first-listed diagnosis is "the diagnosis, condition, problem, or other reason for encounter/visit shown in the medical record to be chiefly responsible for the services provided." If a polyp is removed, the polyp is chiefly responsible for the polypectomy, so might be first. The screening was the reason for encounter, but the service converted. For an encounter where a screening test yields a finding, the finding may be the first-listed diagnosis.

Let's recall specific instructional: "For encounters for screening colonoscopy, the primary diagnosis is Z12.11. If a polyp is found, report K63.5 as secondary. If a malignant neoplasm is found, report C18.x primary and Z12.11 secondary." I think this exact exists? Let's recall from ICD-10-CM Official Guidelines 2023:
Section IV.C.21.c.6? "Encounters for screening for malignant neoplasms" 
"Code Z12.xx is assigned as first-listed diagnosis when the reason for the encounter is specifically the screening exam. If a malignant neoplasm is found during the screening, assign the malignancy as first-listed diagnosis and Z12.xx as additional diagnosis. If a nonmalignant condition is found during the screening, assign the nonmalignant condition as additional diagnosis with Z12.xx as first-listed." Hmm maybe yes.
Let's mentally quote:
"For encounters for screening for malignant neoplasms, code Z12.xx as first-listed if the reason for the visit is specifically the screening. If the screening is performed as part of a general health examination, code the exam first and Z12.xx as additional. If a malignant neoplasm is found during the screening, the malignant neoplasm is coded first, with Z12.xx additional." This is for malignancy only. For benign polyps, Z12.11 first, polyp additional. So primary diagnosis would be Z12.11. But wait if polyp is not malignant but "benign neoplasm" or "polyp"? The guideline only says malignant neoplasm first. That suggests Z12.11 first.

However, the prompt says "During the procedure a single polyp is found and removed" not malignancy. It asks "primary_diagnosis (the ICD-10-CM code that should be reported first for the encounter, given the encounter was scheduled as a screening)." This likely tests that because screening reason is first unless malignancy, so Z12.11. But with polyp removal and modifier PT, many coders might put polyp first? Need know what the expected answer is.

Let's parse item's wording: "A 55-year-old commercial member presents for an average-risk screening colonoscopy. During the procedure a single polyp is found and removed.
Required keys: "modifier" (the single most appropriate modifier from the list for the converted service) and "primary_diagnosis" (the ICD-10-CM code that should be reported first for the encounter, given the encounter was scheduled as a screening)."

They explicitly say "given the encounter was scheduled as a screening" - likely hint primary diagnosis is Z12.11, because the encounter was scheduled as screening; not K63.5? But "converted service" indicates modifier PT. The primary diagnosis maybe should be the condition found? Let's look at phrase "for the converted service" maybe modifier; primary diagnosis "given the encounter was scheduled as a screening" could be Z12.11. They don't supply ICD-10 code list, but Z12.11 is obvious. Need decide.

Let's get precise from coding guidelines for screening colonoscopy with polyp.

ICD-10-CM Official Guidelines FY 2024, Section IV.H? "Ambulatory Surgery" maybe? Section IV.I "Outpatient Services"?
Actually there is an "Outpatient Surgery" specific: "When a patient presents for outpatient surgery, code the diagnosis for which the surgery is performed. If the postoperative diagnosis is known to be different from the preoperative diagnosis at the time the diagnosis is confirmed, select the postoperative diagnosis for coding, since it is the most definitive." That could mean if polyp found and removed, primary Dx K63.5.
But screening colonoscopy with polypectomy is not just surgery? Hmm.

Let's recall from ICD-10-CM Official Guidelines Section IV.L? "Patients receiving diagnostic services only": For encounters for diagnostic tests, first-listed diagnosis is the condition being evaluated? Hmm.

Maybe there is a specific guideline for "colonoscopy" in ICD-10? Let's search memory:
ICD-10-CM Official Guidelines for Coding and Reporting, Section I.C.21.c.5: "Screening" maybe:
"Screening is the testing for disease or disease precursors in seemingly well individuals so that early detection and treatment can be provided. A screening code may be assigned as a first-listed code if the reason for the visit is specifically the screening exam. A screening code may be assigned as an additional code if the screening is done during an encounter for other health problems. If a condition is discovered during the screening then the code for the condition may be assigned as an additional diagnosis."
No distinction malignant.

But for malignant neoplasm screening, Section I.C.2? "Neoplasms" maybe:
"If a patient is admitted for chemotherapy/radiation, etc." Not.

Let's recall exact "Screening" guidelines in ICD-10-CM:
"Z12 Encounter for screening for malignant neoplasms" subsection:
"For encounters for screening for malignant neoplasms, code Z12.xx as first-listed if the reason for the visit is specifically the screening exam. If the screening is performed as part of a general health examination, assign Z00.-- as first-listed and Z12.xx as additional. If a condition is discovered during the screening, assign the code for the condition as first-listed and Z12.xx as additional." Is that it? Wait maybe it says "If a malignant neoplasm is found..."? Let's remember.

From CMS? I recall reading ICD-10-CM guideline:
"Should a condition be discovered during the screening then the code for the condition may be assigned as an additional diagnosis." For neoplasms:
"Encounters for screening for malignant neoplasms (Z12) are first-listed when the reason for the encounter is the screening. If a sign or symptom is present, code the sign/symptom first and Z12 as additional." Hmm.

Let's google memory from actual coding. I know for screening colonoscopy finding polyp, the recommended ICD-10 coding is:
- Primary: Z12.11 (Encounter for screening for malignant neoplasm of colon)
- Secondary: K63.5 (Polyp of colon)
This is common in medical billing for preventive colonoscopy that becomes diagnostic: often use Z12.11 primary and polyp as secondary to indicate screening was reason; for Medicare, if polyp found, use Z12.11 primary? Wait claims: For colonoscopy screening with polypectomy, if billed with Z12.11 primary and K63.5 secondary, it's considered screening and subject to cost-sharing waiver? HCPCS modifier PT indicates converted; diagnosis code should match. Many payers require polyp diagnosis primary when using PT? Let's think.

Medicare preventive services: Screening colonoscopy is covered with no deductible, but if polyp found and removed, the procedure is still considered screening? Under Medicare, a screening colonoscopy is covered as screening even if polyp removed? Actually yes, Medicare waives cost-sharing for screening colonoscopy regardless of polyp removal? The Affordable Care Act requires no cost-sharing for screening colonoscopy that becomes diagnostic? For commercial, preventive service. But coding: HCPCS G0105/G0121, diagnosis V76.51/Z12.11? If polyp found, add K63.5. I recall for Medicare, when a screening colonoscopy results in polypectomy, the claim should be coded with the screening diagnosis (Z12.11) as primary and polyp as secondary, and the appropriate CPT code, but Medicare considers it screening? Hmm.

Let's recall HCPCS modifier PT: "Colorectal cancer screening test; converted to diagnostic test or other procedure" used for Medicare? Actually modifier PT is a HCPCS Level II modifier, effective 2011, for colorectal cancer screening tests that become diagnostic/therapeutic. Medicare requires PT modifier on claims for screening colonoscopies that are converted to diagnostic/therapeutic. Billing instructions: For a Medicare patient, if a screening colonoscopy results in polypectomy, report the appropriate CPT code with modifier PT and the diagnosis code for the polyp? Let's recall.

From CMS MLN Matters MM7044? "Screening and Diagnostic Colonoscopy Billing":
- When a screening colonoscopy is planned and a polyp is removed, the procedure is considered a diagnostic/therapeutic colonoscopy. For Medicare, report the colonoscopy code with modifier PT and the primary diagnosis should be the polyp (e.g., K63.5). The screening diagnosis (Z12.11) should be secondary. This ensures the service is paid under diagnostic benefits, subject to deductible/coinsurance, because it is no longer a screening. Actually yes, because if billed with Z12.11 primary, it might be processed as screening with no cost-sharing. But with PT modifier, the claim is converted to diagnostic, so primary diagnosis maybe polyp to avoid screening payment? Let's investigate.

The question: "A 55-year-old commercial member presents for an average-risk screening colonoscopy. During the procedure a single polyp is found and removed." Required modifier "most appropriate modifier from the list for the converted service" = PT. Primary diagnosis "given the encounter was scheduled as a screening." The phrase "converted service" suggests service changed from screening to diagnostic/therapeutic due to polyp. For converted service, coding convention is primary diagnosis should be the reason for the procedure after conversion, i.e., polyp. Modifier PT communicates that the service converted but the diagnosis should support medical necessity for polyp removal. So primary_diagnosis might be K63.5 (Polyp of colon), not Z12.11.

But the question wording "given the encounter was scheduled as a screening" might be trying to avoid answer "K63.5"? Let's parse exact: "primary_diagnosis (the ICD-10-CM code that should be reported first for the encounter, given the encounter was scheduled as a screening)." If they wanted polyp, they'd say "based on the finding." They say "given the encounter was scheduled as a screening" implies Z12.11. However they also say "single polyp is found and removed" and modifier for converted service. Could be expecting primary diagnosis is the polyp because converted? Need resolve.

Let's examine reference material only gives modifiers, no diagnosis code list. We need know ICD-10 code for "screening colonoscopy" and "polyp of colon." If primary is screening, code Z12.11. If primary is polyp, code K63.5. Which one is "should be reported first" under coding guidelines?

Let's recall official ICD-10-CM guidelines for screening encounters. I can quote from memory:
Chapter 21 (Z codes) guidelines: "Screening"
"Screening is the testing for disease or disease precursors in seemingly well individuals so that early detection and treatment can be provided. A screening code may be assigned as a first-listed code if the reason for the visit is specifically the screening exam. A screening code may be assigned as an additional code if the screening is done during an encounter for other health problems. If the screening is performed during a general physical examination, the screening code is assigned as an additional code. Should a condition be discovered during the screening then the code for the condition may be assigned as an additional diagnosis."
That says condition may be additional, not first. Therefore Z12.11 first. But there is later guideline "If a malignant neoplasm is found during screening, assign malignancy as first-listed"? Let's recall: In the same chapter, "Encounters for screening for malignant neoplasms" maybe:
"Code Z12.xx as first-listed when the reason for the visit is specifically the screening. If a malignancy is found during screening, the malignancy is first-listed and Z12.xx is additional." If benign polyp, not malignancy, so Z12.11 first. Yes. That would make primary diagnosis Z12.11. But wait if the polyp is removed, is the condition "discovered" and treated? The guideline "should a condition be discovered during screening... code for the condition may be assigned as an additional diagnosi

We need to process the ledger from the given starting accumulators through all lines, tracking accumulators (deductible balances and OOPM balances) for each member and the family total. The plan is embedded deductible, individual in-network $2500, family $5000, out-of-network individual $5000. Copays credit deductible and OOPM. Coinsurance is applied after deductible. Copays are flat amounts per service type. For specialist office visit, copay $50; urgent care $60; generic retail pharmacy $10. For inpatient admission, no copay listed, so it goes to deductible and coinsurance. Preventive services in-network are free, but out-of-network preventive is subject to out-of-network deductible/coinsurance. The plan says: "In-network preventive services required to be covered without cost share are paid at 100% of the allowed amount and are not subject to the deductible, coinsurance, or a copay." Out-of-network preventive: "An out-of-network preventive service is subject to the out-of-network deductible and coinsurance." So for claim 15 (routine immunisation, out-of-network), it will be subject to OON deductible and coinsurance.

We need to determine member responsibility and plan paid for each claim, based on accumulators at the time of the claim. The accumulators include deductible balance (running total of deductible_applied) and OOPM balance (running total of member_responsibility). The deductible thresholds: for in-network, the effective deductible limit is the lesser of individual remaining (individual threshold - member's deductible balance) and family remaining (family threshold - family deductible balance). Because embedded, an individual can hit their individual deductible even if family hasn't. For out-of-network, the deductible limit is the OON individual threshold (5000) minus the member's deductible balance (same balance). The family deductible balance is the sum of all members' deductible_applied, but the family threshold (5000) only applies to in-network claims; out-of-network claims are not limited by the family threshold, but their deductible_applied still adds to the family balance. The family OOPM balance is the sum of all members' OOPM balances; the family OOPM threshold is 11000 for in-network, but out-of-network OOPM individual is 11000. For out-of-network claims, the member's OOPM balance is measured against the OON individual OOPM (11000) and in-network individual OOPM (5500) doesn't cap. Actually, the plan says: "Individual (out-of-network) ............ 11000.00" and "Once a member reaches the out-of-pocket maximum the plan pays 100% of the allowed amount for covered services for the remainder of the plan year." It doesn't specify separate family OOPM for out-of-network. The family OOPM of 11000 is in-network. So out-of-network claims are subject to the individual out-of-network OOPM of 11000. However, the family OOPM balance is still accumulated from all members' member_responsibility, but the family OOPM threshold (in-network) of 11000 only applies to in-network claims? The plan says: "Family (in-network) .................... 11000.00". It doesn't list a family out-of-network OOPM. So out-of-network claims are not limited by the family OOPM; they only use the individual out-of-network OOPM. But the family OOPM balance accumulates all member responsibility regardless of network, but the family threshold is not used for out-of-network claims. However, for an in-network claim, the effective OOPM limit is the lesser of the member's individual OOPM (in-network 5500) and the family OOPM (11000) remaining? Typically, embedded OOPM also applies: individual OOPM can be reached, and family OOPM. But the plan says "Once a member reaches the out-of-pocket maximum the plan pays 100%..." It doesn't specify that the family OOPM applies to individual out-of-network? For out-of-network, the individual OOPM is 11000, so family OOPM is irrelevant. For in-network, the individual OOPM is 5500, and family OOPM is 11000. So for in-network claims, the member's OOPM limit is the lesser of individual remaining (5500 - member's OOPM balance) and family remaining (11000 - family OOPM balance). That's typical for embedded OOPM. We'll apply that.

Now, we need to process each line from 1 to 17, updating accumulators, including adjustments. The starting accumulators: A: deductible balance 60.69, OOPM balance 60.69; B: deductible 383.93, OOPM 924.55; C: deductible 1524.34, OOPM 2116.83; family deductible 1968.96, family OOPM 3102.07. (These are sums of individual? Actually family deductible is total of individual deductible balances, because each member's deductible credits accumulate. So family deductible balance = sum of A, B, C deductible balances: 60.69+383.93+1524.34 = 1968.96, correct. Family OOPM balance = sum of OOPM: 60.69+924.55+2116.83 = 3102.07, correct.)

Now, we process each line.

Line 1: Claim 1, C (child), Inpatient admission with surgery, in-network. Allowed amount 10074.70. No copay for inpatient. So cost share: deductible then coinsurance. For in-network, we need to see how much deductible applies. C's deductible balance: 1524.34. Individual deductible threshold: 2500. So remaining individual deductible: 2500 - 1524.34 = 975.66. Family deductible balance: 1968.96, family threshold 5000, remaining family: 5000 - 1968.96 = 3031.04. The effective deductible remainder is the lesser of individual remainder (975.66) and family remainder (3031.04) = 975.66. So deductible_applied = min(10074.70, 975.66) = 975.66. Member responsibility from deductible: 975.66. After that, remaining allowed: 10074.70 - 975.66 = 9099.04. Then coinsurance 30% member: 0.30 * 9099.04 = 2729.712, round half up to 2729.71. So total member responsibility = 975.66 + 2729.71 = 3705.37. Plan paid = allowed - member responsibility = 10074.70 - 3705.37 = 6369.33. Check: deductible_applied = 975.66. Copay_amount = 0. Coinsurance_amount = 2729.71. This claim updates accumulators: C's deductible balance becomes 1524.34 + 975.66 = 2500.00 (exactly individual deductible met). C's OOPM balance becomes 2116.83 + 3705.37 = 5822.20. Family deductible balance becomes 1968.96 + 975.66 = 2944.62. Family OOPM balance becomes 3102.07 + 3705.37 = 6807.44.

Now Line 2: Claim 2, A (subscriber), Specialty pharmacy administration, in-network. Allowed amount 4603.57. No copay (not listed as office visit, it's specialty pharmacy admin, likely no copay, so deductible+coinsurance). A's deductible balance: 60.69. Individual remaining: 2500 - 60.69 = 2439.31. Family deductible balance: 2944.62, family remaining: 5000 - 2944.62 = 2055.38. Lesser is 2055.38. So deductible_applied = min(4603.57, 2055.38) = 2055.38. That's the family remaining, so after this, the family deductible will be met (5000). A's deductible will be 60.69 + 2055.38 = 2116.07, not yet 2500. After deductible, remaining allowed: 4603.57 - 2055.38 = 2548.19. Coinsurance 30% member: 0.30 * 2548.19 = 764.457 -> 764.46. Total member responsibility = 2055.38 + 764.46 = 2819.84. Plan paid = 4603.57 - 2819.84 = 1783.73. Deductible_applied = 2055.38. Copay = 0. Coinsurance = 764.46. Update: A's deductible balance = 60.69 + 2055.38 = 2116.07. A's OOPM balance = 60.69 + 2819.84 = 2880.53. Family deductible balance = 2944.62 + 2055.38 = 4999.99? Actually 2944.62 + 2055.38 = 5000.00 exactly (since 2944.62 + 2055.38 = 5000.00). Family OOPM balance = 6807.44 + 2819.84 = 9627.28.

Line 3: Claim 3, B (spouse), Specialist office visit, in-network. Allowed 339.69. This is a specialist office visit, so copay $50. Copay credits deductible and OOPM. The plan says: "Copays DO credit the deductible. Copays always credit the out-of-pocket maximum." So for this service, the member pays the copay, and that amount counts towards deductible and OOPM. But does the copay apply instead of deductible/coinsurance? Usually, copay is the cost share for the office visit, and it's not subject to deductible. The plan says: "Primary care office visit 25.00 copay; Specialist office visit 50.00 copay; ... Copays DO credit the deductible." So for a specialist office visit, the member pays the copay, and that copay amount is applied to the deductible (credited) and OOPM. The plan does not say that the copay is in addition to deductible; it replaces the deductible/coinsurance for that service. So the allowed amount is not used to calculate coinsurance; the member responsibility is just the copay. However, the deductible credit is the copay amount, up to the remaining deductible. The plan: "Copays DO credit the deductible." So we add the copay to the deductible balance, but only to the extent of remaining deductible. Also, the copay is the member responsibility. So for claim 3, member responsibility = 50.00. Deductible_applied = min(50.00, remaining deductible). The deductible remaining for B: B's deductible balance 383.93, individual remaining 2500-383.93=2116.07. Family deductible balance is 5000.00? After line 2, family deductible is exactly 5000.00? Let's check: line 2 gave family deductible 5000.00 exactly. So family remaining is 0. Since embedded, the effective deductible remainder for in-network is the lesser of individual remaining and family remaining. Family remaining is 0. So no more deductible can be applied for in-network claims, even if individual remaining is >0. That means deductible_applied = 0.00 for this claim. But does the copay still credit the deductible? The addendum says: "Once the applicable threshold is met, deductible_applied is 0.00, including for a copay that would otherwise credit the deductible." So yes, if the family deductible is met, then no deductible credit is applied. So deductible_applied = 0.00. Member responsibility = 50.00 (copay). Plan paid = allowed - member responsibility = 339.69 - 50.00 = 289.69. Copay_amount = 50.00, coinsurance_amount = 0.00. Update accumulators: B's deductible balance unchanged (383.93) because deductible_applied=0. B's OOPM balance: 924.55 + 50.00 = 974.55. Family deductible unchanged (5000.00). Family OOPM: 9627.28 + 50.00 = 9677.28.

Line 4: Claim 4, B (spouse), Inpatient admission, out-of-network. Allowed 15484.21. No copay. OON deductible threshold: individual 5000. B's deductible balance: 383.93. So OON deductible remaining: 5000 - 383.93 = 4616.07. For OON, family deductible threshold does not apply (only individual OON). So deductible_applied = min(15484.21, 4616.07) = 4616.07. After that, B's deductible balance becomes 383.93 + 4616.07 = 5000.00 (OON individual deductible met). Then remaining allowed = 15484.21 - 4616.07 = 10868.14. OON coinsurance: 50% member -> 0.50 * 10868.14 = 5434.07. So total member responsibility = 4616.07 + 5434.07 = 10050.14. Plan paid = 15484.21 - 10050.14 = 5434.07. Check: deductible_applied = 4616.07, copay=0, coinsurance=5434.07. Update accumulators: B's deductible balance: 5000.00. B's OOPM balance: 974.55 + 10050.14 = 11024.69. That exceeds in-network individual OOPM (5500) but OON individual OOPM is 11000, so B hasn't reached OOPM max yet? Actually 11024.69 > 11000, so B has exceeded the OON OOPM threshold. But OOPM is a cap: once reached, plan pays 100% for the rest of the year. Since this claim's member responsibility pushed the balance over 11000, we need to cap the member responsibility at the amount that brings the OOPM balance to exactly 11000. The plan says: "Once a member reaches the out-of-pocket maximum the plan pays 100% of the allowed amount for covered services for the remainder of the plan year." That means that for the claim that causes the OOPM to be reached, the member responsibility is limited so that the OOPM balance after the claim equals the OOPM threshold. So we need to calculate the allowed amount, and the member responsibility should be such that the OOPM balance becomes 11000, and the plan pays the rest. The OOPM balance before claim: 974.55. The OOPM threshold for OON individual is 11000. So the maximum member responsibility that can be applied is 11000 - 974.55 = 10025.45. But the calculated member responsibility from deductible and coinsurance would be 10050.14, which is more than 10025.45. So we cap the member responsibility at 10025.45. That means the sum of deductible_applied and coinsurance will be limited. However, deductible_applied is determined first, and then coinsurance. But the cap applies to the total member responsibility. So we need to adjust. The correct approach: determine the member responsibility as the sum of deductible and coinsurance, but cap at the amount needed to reach OOPM. If the cap is less than the sum, then the plan pays the difference. The deductible_applied and coinsurance amounts should be reported as the amounts that would have been attributed, but the cap may reduce coinsurance. Typically, you still apply the deductible to the extent it would have been, and then reduce coinsurance. So we compute deductible_applied = min(allowed, remaining deductible) = 4616.07. That would bring B's deductible to 5000. Then after that, the remaining allowed is 10868.14, and coinsurance would be 5434.07. But total member responsibility would be 4616.07 + 5434.07 = 10050.14. To cap at 10025.45, we need to reduce member responsibility by 24.69. The reduction would come from the coinsurance amount, because the deductible is legitimately applied. So coinsurance becomes 5434.07 - 24.69 = 5409.38. Then total member responsibility = 4616.07 + 5409.38 = 10025.45. Plan paid = 15484.21 - 10025.45 = 5458.76. Check: deductible_applied = 4616.07, copay=0, coinsurance=5409.38. But is the deductible_applied still 4616.07? Yes, because the deductible balance needed to reach 5000, and the allowed amount is large enough. So that seems correct. The OOPM balance after claim: B's OOPM = 11000.00. Family OOPM balance: before claim 9677.28, add B's member responsibility 10025.45 = 19702.73. Family deductible balance: before 5000.00, add deductible_applied 4616.07 = 9616.07. But note: family deductible balance is the sum of all members' deductible balances. Since B's deductible balance went from 383.93 to 5000.00, an increase of 4616.07, so family deductible increases by that amount. So family deductible: 5000.00 + 4616.07 = 9616.07. So final accumulators after line 4: A: ded 2116.07, OOP 2880.53; B: ded 5000.00, OOP 11000.00; C: ded 2500.00, OOP 5822.20; family ded: 2116.07+5000+2500 = 9616.07; family OOP: 2880.53+11000.00+5822.20 = 19702.73.

Now Line 5: Claim 5, B (spouse), Urgent care visit, in-network. Allowed 181.01. Urgent care copay: $60. Copay credits deductible. For in-network, effective deductible remainder: B's individual remaining: 2500 - 5000? Actually B's deductible balance is 5000.00, which exceeds the in-network individual threshold of 2500. Since deductible credits are cumulative, the balance is 5000. The in-network individual threshold is 2500, so the member has met the in-network deductible. The effective deductible remainder for in-network is the lesser of individual remaining (which is max(0, 2500 - current balance) since balance 5000 > 2500, remaining = 0) and family remaining (family threshold 5000, family deductible balance 9616.07 > 5000, so remaining 0). So no deductible applies. So deductible_applied = 0.00. Member responsibility = copay $60.00. Plan paid = 181.01 - 60.00 = 121.01. However, B's OOPM balance is 11000.00, which is the OON OOPM threshold. But for in-network claims, the OOPM cap is the individual in-network OOPM of 5500. But B's OOPM balance is already 11000, which exceeds 5500. So B has already reached the in-network individual OOPM. Actually, the plan says: "Once a member reaches the out-of-pocket maximum the plan pays 100% of the allowed amount for covered services for the remainder of the plan year." Which OOPM applies? For in-network, the individual OOPM is 5500. So if B's OOPM balance is 11000, that means B has exceeded the in-network OOPM. So for in-network claims, the plan should pay 100% with no member cost sharing. However, the OOPM cap is applied per claim based on the applicable OOPM threshold. The plan says: "Individual (in-network) ... 5500.00" and "Once a member reaches the out-of-pocket maximum the plan pays 100%...". So if a member's OOPM balance is at or above 5500, then for in-network services, no member cost sharing is required. So for this claim, since B's OOPM balance is 11000 >= 5500, the member responsibility should be 0.00. But wait, is the OOPM cap applied per network? The plan indicates separate thresholds for in-network and out-of-network. The OOPM balance is a single accumulation, but the cap that triggers 100% coverage depends on the network of the service. For in-network, the cap is 5500 individual; for out-of-network, 11000 individual. So if a member's OOPM balance is above 5500, they have met the in-network OOPM, so in-network services are covered at 100%. So for claim 5, member responsibility = 0.00, plan paid = 181.01. Deductible_applied = 0. Copay = 0? Actually, even though it's an urgent care visit, the copay is waived because OOPM is met. So we set member responsibility 0. Plan paid 181.01. Update: B's OOPM balance unchanged (11000.00). No deductible credit. Family OOPM unchanged (19702.73). Family deductible unchanged.

Line 6: Claim 6, A (subscriber), Urgent care visit, in-network. Allowed 213.67. Copay $60. A's deductible balance: 2116.07. Individual remaining: 2500 - 2116.07 = 383.93. Family deductible balance: 9616.07. Family remaining: 5000 - 9616.07 = negative, so 0. So effective deductible remainder = 0. So deductible_applied = 0.00. Member responsibility: normally copay $60. But check OOPM: A's OOPM balance is 2880.53. In-network individual OOPM is 5500. So not reached. So member responsibility = 60.00. Plan paid = 213.67 - 60.00 = 153.67. Copay_amount = 60.00. Deductible_applied = 0.00 (since family deductible met). Update: A's OOPM becomes 2880.53 + 60.00 = 2940.53. Family OOPM: 19702.73 + 60.00 = 19762.73. No deductible change.

Line 7: Claim 7, C (child), Specialist office visit, in-network. Allowed 330.22. Copay $50. C's deductible balance: 2500.00 (met). Individual remaining: 0. Family remaining: 0 (since family deductible 9616.07 > 5000). So deductible_applied = 0. C's OOPM balance: 5822.20. In-network OOPM threshold 5500. Since C's OOPM balance is 5822.20 > 5500, C has met the in-network OOPM. So member responsibility = 0.00, plan paid = 330.22. Copay waived. Update: no change to OOPM (balance stays 5822.20). No deductible.

Line 8: Claim 8, C (child), Sleep study, out-of-network. Allowed 1805.31. No copay. OON deductible: individual threshold 5000. C's deductible balance: 2500.00. So remaining OON deductible: 5000 - 2500 = 2500.00. So deductible_applied = min(1805.31, 2500) = 1805.31. After that, remaining allowed = 0, so no coinsurance. Member responsibility = deductible_applied = 1805.31. Plan paid = 0.00. Check OOPM: C's OOPM balance before: 5822.20. For OON, OOPM threshold is 11000. So adding 1805.31 gives 7627.51, still below 11000. So no cap. Update: C's deductible balance: 2500 + 1805.31 = 4305.31. C's OOPM: 5822.20 + 1805.31 = 7627.51. Family deductible: 9616.07 + 1805.31 = 11421.38. Family OOPM: 19762.73 + 1805.31 = 21568.04.

Line 9: ADJUSTMENT to Claim 6, 2026-04-11, A. Allowed amount corrected to 277.77 (up from 213.67). Billed charge 513.87. So we need to unwind the original Claim 6's credits from accumulators and re-adjudicate with the new allowed amount 277.77. Original Claim 6 was processed as: allowed 213.67, member responsibility 60.00 copay, deductible_applied 0, plan paid 153.67. It credited A's OOPM by 60.00, family OOPM by 60.00. No deductible credit. So we need to reverse those credits: subtract 60.00 from A's OOPM and family OOPM. Then re-adjudicate Claim 6 at allowed 277.77, as of the current accumulators (after line 8). The current accumulators before adjustment (after line 8): A: ded 2116.07, OOP 2940.53; B: ded 5000.00, OOP 11000.00; C: ded 4305.31, OOP 7627.51; family ded: 11421.38; family OOP: 2156

We need to process the ledger line by line, starting from the given initial accumulators. The plan document specifies: Aggregate deductible (family deductible must be met before any member gets coinsurance). In-network deductible: family 6400, but no individual limit; aggregate means the family amount must be satisfied. Out-of-network deductible: individual 6400, measured against the member's single deductible balance (same balance as in-network). Out-of-network coinsurance is 40% after the out-of-network deductible is met. Out-of-network OOPM individual is 14000. In-network OOPM individual 7000, family 14000. Preventive services in-network free; out-of-network preventive is subject to deductible and coinsurance. So for line 5, annual wellness visit out-of-network is not free; it's subject to out-of-network deductible and coinsurance.

We have members A, B, C. Initial accumulators (before line 1):
A: deductible balance (total of deductible_applied so far) = 1729.94, OOPM balance (member's total responsibility paid so far) = 1762.13
B: deductible = 0.00, OOPM = 0.00
C: deductible = 1382.40, OOPM = 1945.98
Family total deductible (sum of all family members' deductible_applied) = 3112.34, Family OOPM = 3708.11

Note: The family deductible is aggregate, so the family deductible threshold is 6400. No individual deductible threshold. So for any in-network claim, deductible_applied is the amount applied to the family deductible until the family deductible reaches 6400. The member's individual deductible balance is tracked but not used for in-network claims; the aggregate structure says "the plan pays no coinsurance for any member until total family credits reach the family deductible amount". So the deductible_applied for an in-network claim is the lesser of the allowed amount and the remaining family deductible (6400 - family deductible balance). The member's individual balance is just a running total of their deductible_applied, but the threshold is the family one. So for in-network, we look at the family deductible remainder. Out-of-network: the deductible threshold is the out-of-network individual deductible of 6400, but the balance used is the member's same single deductible balance (which includes both in-network and out-of-network credits). So for out-of-network, deductible_applied is the lesser of allowed amount and the remaining out-of-network deductible (6400 - member's deductible balance). Note: The out-of-network deductible is 6400, and the member's deductible balance is the same as the in-network balance. The family deductible does not apply to out-of-network claims. So we need to track:

- Family deductible balance (sum of all deductible_applied from in-network claims only? Actually the family deductible is the total family credits, but the plan says "In-network and out-of-network deductible credits accumulate to a SINGLE member deductible balance." The family deductible is "total family credits" before coinsurance begins. The document says "aggregate — the plan pays no coinsurance for any member until total family credits reach the family deductible amount." So total family credits across all members, regardless of in-network or out-of-network? The deductible is aggregate, and it says "total family credits reach the family deductible amount". The family deductible is an in-network amount (6400). But out-of-network deductible credits accumulate to the member's balance, and that balance is part of the family total. I think the family deductible threshold is the 6400, and it applies to all claims, in-network and out-of-network? Let's review the deductible section:

Deductible
  Individual (in-network) ................ 3200.00
  Family (in-network) .................... 6400.00
  Structure .............................. AGGREGATE — the plan pays no coinsurance for any member until total family credits reach the family deductible amount. There is no individual deductible under this structure.
  Out-of-network (individual) ............ 6400.00
  In-network and out-of-network deductible credits accumulate to a SINGLE member deductible balance. The amount above is the threshold that balance is measured against when the service is out-of-network.

Interpretation: For in-network, the deductible is the family deductible of 6400, aggregated. There is no individual deductible threshold; the family amount must be satisfied. For out-of-network, the deductible is the out-of-network individual deductible of 6400, and it's measured against the member's single balance. That implies that out-of-network services are not subject to the family deductible; they have their own individual deductible. So the family deductible threshold only applies to in-network services. The "total family credits" probably refers to the sum of all family members' deductible credits from in-network claims? Or does it include out-of-network credits? The phrase "In-network and out-of-network deductible credits accumulate to a SINGLE member deductible balance" means each member has one balance that sums both in-network and out-of-network deductible_applied. Then the family deductible threshold is measured against the total family credits? But the family deductible is an in-network amount, and the structure says aggregate "until total family credits reach the family deductible amount". If out-of-network claims also credit that same balance, then they would count toward the family deductible. But the out-of-network deductible is separate; it's an individual out-of-network deductible of 6400. So for an out-of-network claim, we first check if the member's individual deductible balance has reached 6400; if not, the claim applies to that deductible. That deductible_applied also adds to the member's balance and therefore to the family total (since family total is sum of all members' balances). That could inadvertently help satisfy the family deductible. But the family deductible is only for in-network coinsurance. The plan says "the plan pays no coinsurance for any member until total family credits reach the family deductible amount." That could mean that for any member to get coinsurance on any service (in-network or out-of-network), the family deductible must be met? That seems odd because the out-of-network deductible is individual. But the aggregate structure is "the plan pays no coinsurance for any member until total family credits reach the family deductible amount." That's a blanket statement. It doesn't distinguish in-network vs out-of-network. So maybe all coinsurance, both in and out-of-network, is subject to meeting the family deductible (6400) first, regardless of the out-of-network individual deductible. But then the out-of-network individual deductible of 6400 would be a separate hurdle? The document says: "Out-of-network (individual) ............ 6400.00" and "In-network and out-of-network deductible credits accumulate to a SINGLE member deductible balance. The amount above is the threshold that balance is measured against when the service is out-of-network." So when a service is out-of-network, the deductible threshold is the out-of-network individual deductible (6400) applied to the member's single balance. But the aggregate structure says no coinsurance until total family credits reach the family deductible amount. That seems contradictory. Likely, the aggregate structure applies only to the in-network deductible, and the out-of-network deductible is individual and separate. The phrase "There is no individual deductible under this structure" refers to in-network. So we should interpret: For in-network claims, the deductible is the family aggregate deductible (6400), and the member's individual deductible balance is not used as a threshold; instead, the family total must hit 6400 before any in-network coinsurance applies. For out-of-network claims, the deductible is the out-of-network individual deductible (6400) applied to the member's single balance, and the family deductible does not apply. The "aggregate" structure is specifically for the in-network deductible. The plan document says "Structure .............................. AGGREGATE — the plan pays no coinsurance for any member until total family credits reach the family deductible amount." That is under the deductible section, which first lists individual (in-network) and family (in-network). So the aggregate structure refers to the in-network deductible. So out-of-network claims are not subject to the family deductible. They are subject to the out-of-network individual deductible. So we will process accordingly.

Now, for out-of-network coinsurance: 40% member, 60% plan after deductible is met. For in-network: 10% member, 90% plan after family deductible is met.

Out-of-pocket maximums: Individual in-network 7000, family in-network 14000, individual out-of-network 14000. The plan says "Once a member reaches the out-of-pocket maximum the plan pays 100% of the allowed amount for covered services for the remainder of the plan year." Which OOPM applies? For in-network services, the OOPM is the individual in-network (7000) and family in-network (14000). For out-of-network services, it's the individual out-of-network (14000). The member's OOP balance is the total member responsibility paid so far. When a member's OOP balance reaches the applicable OOPM, further claims for that member have member responsibility 0. We need to track per-member OOP balances and also family OOP balance (sum of all member responsibilities). The family OOPM is 14000 for in-network, but does it apply to out-of-network? The OOPM section says "Individual (in-network) ................ 7000.00 / Family (in-network) .................... 14000.00 / Individual (out-of-network) ............ 14000.00". So out-of-network has its own individual OOPM, no family OOPM for out-of-network. The family OOPM is only for in-network. So for in-network claims, we check if the member's individual OOP balance has reached 7000 (or family OOP balance reached 14000) to cap cost sharing. The family OOPM applies to in-network services; once the family OOP reaches 14000, all family members have 0 cost sharing for in-network services. For out-of-network, only the individual out-of-network OOPM 14000 applies; family OOPM doesn't apply to out-of-network.

Now, the ledger: we need to process all lines, including the void and adjustment, and then report final components for claims 6, 15, 20. Claim 6 is an out-of-network claim for A, originally line 6, then adjusted at line 16. So claim 6's final components are from the adjustment. Claim 15 is C's inpatient admission with surgery in-network, no adjustment. Claim 20 is A's cardiac stress test in-network, no adjustment. We must compute the final components as they stand after all lines processed (including the adjustment of claim 6). So we need to track the accumulators and re-adjudicate claim 6 at line 16 with the corrected allowed amount, using the accumulators as they stand at that moment (i.e., after lines 1-5, 7-15? Actually the adjustment at line 16 says: "ADJUSTMENT to Claim 6 ... Allowed amount corrected to 36759.38". The process: undo the credits from claim 6 (original) from accumulators, then re-adjudicate with new allowed amount against accumulators as they stand at the point the adjustment is processed. The original claim 6 was processed at line 6. We need to first process lines 1-5, then line 6 (original claim 6), then lines 7-15, then at line 16 we undo claim 6 and re-do it. Then lines 17-20. So we'll compute the accumulators step by step.

We'll need to keep track of these accumulators for each member and family:

- Member deductible balance (total deductible_applied so far)
- Member OOP balance (total member_responsibility so far)
- Family deductible balance (sum of all member deductible_applied from all claims, regardless of network? But out-of-network claims also add to member deductible balance, so they add to family total. However, the family deductible threshold is only for in-network coinsurance. We need to track family deductible balance to determine when the family deductible is met for in-network claims. So we'll track family_deductible_balance = sum of all deductible_applied across all members. That is used to check the family deductible threshold (6400) for in-network claims. For out-of-network claims, we don't use the family deductible threshold; we use the member's individual deductible balance vs 6400. So the family balance is just a running total.
- Family OOP balance: sum of all member_responsibility across all members. This is used to check the family OOPM (14000) for in-network claims. For out-of-network claims, we only check individual OOPM (14000), not family.

We'll also need to handle the void of claim 1 at line 11. Claim 1 is an in-network claim for A. The void will remove its credits from all accumulators. Then later claims after that will be processed with the corrected accumulators. So we need to compute the original claim 1's components and then later subtract them.

We need to compute each claim's member_responsibility, plan_paid, deductible_applied, copay_amount (0), coinsurance_amount. The coinsurance_amount is the member's coinsurance liability (the 10% or 40% after deductible). The member_responsibility = deductible_applied + copay + coinsurance_amount. Plan_paid = allowed amount - member_responsibility.

We'll track per-member: deductible_balance, oop_balance. Family: ded_total, oop_total.

Initial state (before line 1):
A: ded=1729.94, oop=1762.13
B: ded=0.00, oop=0.00
C: ded=1382.40, oop=1945.98
Family: ded_total = 3112.34, oop_total = 3708.11

Now process line by line.

Line 1 — Claim 1 — A, in-network, allowed 1553.18.
In-network: family deductible threshold 6400. Current family ded_total = 3112.34. Remaining family deductible = 6400 - 3112.34 = 3287.66. The allowed amount is 1553.18, which is less than that. So deductible_applied = 1553.18 (all of allowed goes to deductible). Member responsibility = deductible_applied = 1553.18. Coinsurance = 0. Plan_paid = 0. So:
A: ded increases by 1553.18 => 1729.94 + 1553.18 = 3283.12. oop increases by 1553.18 => 1762.13 + 1553.18 = 3315.31.
Family: ded_total = 3112.34 + 1553.18 = 4665.52. oop_total = 3708.11 + 1553.18 = 5261.29.

Line 2 — Claim 2 — A, in-network, allowed 21710.91.
Family ded_total = 4665.52, remaining = 6400 - 4665.52 = 1734.48. So deductible_applied = min(21710.91, 1734.48) = 1734.48. After that, family deductible is met (reaches 6400). Then remaining allowed amount = 21710.91 - 1734.48 = 19976.43. This remaining amount is subject to 10% coinsurance (member). So coinsurance = 19976.43 * 0.10 = 1997.64 (rounded? 1997.643 => 1997.64). Member responsibility = deductible_applied + coinsurance = 1734.48 + 1997.64 = 3732.12. Plan_paid = 19976.43 - 1997.64 = 17978.79 (actually coinsurance is member's share, plan pays 90% of remaining, so plan_paid = 19976.43 * 0.90 = 17978.787 => 17978.79). Check: allowed = 21710.91, member = 3732.12, plan = 17978.79, sum = 3732.12+17978.79=21710.91. Good.
Now update accumulators: A: ded += 1734.48 => 3283.12 + 1734.48 = 5017.60. oop += 3732.12 => 3315.31 + 3732.12 = 7047.43.
Family: ded_total += 1734.48 => 4665.52 + 1734.48 = 6400.00 (exactly). oop_total += 3732.12 => 5261.29 + 3732.12 = 8993.41.
Note: Family deductible is now met. So for subsequent in-network claims, deductible_applied = 0.

Line 3 — Claim 3 — C, in-network, allowed 454.13.
Family deductible is already met (6400). So deductible_applied = 0. Coinsurance = 10% of allowed = 454.13 * 0.10 = 45.413 => 45.41. Member responsibility = 45.41. Plan_paid = 454.13 - 45.41 = 408.72.
Update: C: ded unchanged (0 added), so ded remains 1382.40. oop: 1945.98 + 45.41 = 1991.39.
Family: ded_total unchanged (6400), oop_total += 45.41 => 8993.41 + 45.41 = 9038.82.

Line 4 — Claim 4 — A, in-network, allowed 17679.63.
Family deductible met, so deductible_applied = 0. Coinsurance = 10% of 17679.63 = 1767.963 => 1767.96. Member responsibility = 1767.96. Plan_paid = 17679.63 - 1767.96 = 15911.67.
Update: A: ded unchanged (5017.60). oop: 7047.43 + 1767.96 = 8815.39.
Family: oop_total += 1767.96 => 9038.82 + 1767.96 = 10806.78.

Line 5 — Claim 5 — C, out-of-network, allowed 771.12. Service: Annual wellness visit, out-of-network. Out-of-network preventive is not free; subject to deductible and coinsurance. So out-of-network claim.
For out-of-network, deductible threshold is individual out-of-network 6400, measured against C's deductible balance. C's current deductible balance is 1382.40. Remaining out-of-network deductible = 6400 - 1382.40 = 5017.60. Allowed amount is 771.12, less than that. So deductible_applied = 771.12. Member responsibility = deductible_applied = 771.12. Coinsurance = 0. Plan_paid = 0.
Update: C: ded += 771.12 => 1382.40 + 771.12 = 2153.52. oop += 771.12 => 1991.39 + 771.12 = 2762.51.
Family: ded_total += 771.12 => 6400 + 771.12 = 7171.12. (Family deductible balance exceeds 6400, but that's fine; it's just a running total.) oop_total += 771.12 => 10806.78 + 771.12 = 11577.90.

Line 6 — Claim 6 — A, out-of-network, allowed originally 25351.30. This is the original claim, later adjusted. We'll process with original allowed amount first, then later undo and redo. So original claim 6: A, out-of-network, allowed 25351.30.
A's deductible balance currently: 5017.60. Out-of-network deductible threshold 6400. Remaining: 6400 - 5017.60 = 1382.40. So deductible_applied = min(25351.30, 1382.40) = 1382.40. After that, A's deductible balance reaches 6400. Then remaining allowed = 25351.30 - 1382.40 = 23968.90. Coinsurance = 40% of that = 23968.90 * 0.40 = 9587.56 (since 23968.90 * 0.4 = 9587.56 exactly? 23968.90 * 0.4 = 9587.56). So member responsibility = 1382.40 + 9587.56 = 10969.96. Plan_paid = 23968.90 * 0.60 = 14381.34 (or 25351.30 - 10969.96 = 14381.34). Check: 14381.34 + 10969.96 = 25351.30. Good.
Now we need to check OOP max for out-of-network: individual out-of-network OOPM is 14000. A's current OOP balance before this claim is 8815.39. After adding this member responsibility, OOP would become 8815.39 + 10969.96 = 19785.35, which exceeds 14000. So we need to apply OOPM cap. The OOPM applies to the member's responsibility for the claim. The member's responsibility should be limited so that the total OOP for the year does not exceed 14000. So we compute: maximum allowed member responsibility for this claim = max(0, 14000 - current OOP balance). Current OOP = 8815.39. So remaining room = 14000 - 8815.39 = 5184.61. Therefore, member responsibility for this claim is capped at 5184.61. The plan pays the rest. So member_responsibility = 5184.61. Plan_paid = allowed amount - member_responsibility = 25351.30 - 5184.61 = 20166.69. The deductible_applied and coinsurance amounts are what they would have been without the cap, but the actual member responsibility is capped. The ledger components for the claim: deductible_applied = 1382.40, coinsurance_amount = 9587.56, but member_responsibility = 5184.61 (capped). The plan_paid = 25351.30 - 5184.61 = 20166.69. So we need to report the components as: deductible_applied = 1382.40, copay = 0, coinsurance_amount = 9587.56, member_responsibility = 5184.61, plan_paid = 20166.69. The OOP balance increases by the actual member responsibility, so A's OOP becomes 14000 (exactly 8815.39 + 5184.61 = 14000.00). The deductible balance increases by the full deductible_applied (1382.40) even though member responsibility capped? Yes, deductible_applied is the amount credited toward the deductible, regardless of OOP cap. That's standard. So A's deductible balance becomes 5017.60 + 1382.40 = 6400.00. Family ded_total: 7171.12 + 1382.40 = 8553.52. OOP_total: previous 11577.90 + 5184.61 = 16762.51. Note: Family OOP total is sum of all member responsibilities, which includes the capped amount. So family OOP becomes 16762.51. But family OOPM is 14000 for in-network. However, this is out-of-network

We need solve carefully. Need produce JSON only. We need compute ledger. Need understand plan.

We have family accumulators before line1:
A ded 904.50 oop 904.50

Family ded 904.50 oop 904.50.

Plan embedded individual ded 1500 in-network, family 3000 in-network. OOP individual 6000 in-network, family 12000 in-network, out-of-network OOP individual 12000. OON deductible individual 3000, same single member deductible balance? Important: In-network and out-of-network deductible credits accumulate to a SINGLE member deductible balance. The amount above is threshold that balance is measured against when OON. So for OON, deductible applied = lesser of allowed and room left under OON individual deductible (3000), measured against member's single deductible balance (which starts prior credits). It says out-of-network individual remainder measured against member's same single deductible balance. Family amounts in-network do not limit OON. OON claims coinsurance 40% after deductible. OOP credits (member responsibility) still accumulate to member and family balances.

Need process each line, handle copays, deductible, coinsurance, OOP max.

We need report final components for claims 4,13,16. Claim 4 was voided line15, so final components on books for claim4? They ask final components on books for claims 4,13,16 — for a claim adjusted etc. Claim 4 voided => every component 0.00. Need verify: line4 then void line15 unwinds. Claim4 final components zero.

Need compute ending accumulators after all lines, with voids/unwind.

Need each claim components: deductible_applied, copay, coinsurance, member_responsibility, plan_paid. For in-network services: office visit copays etc. Specialist 60 copay, primary 30, urgent 75. Copays do not credit deductible, always credit OOP. Deductible/coinsurance after deductible for non-copay? Need determine services subject to deductible/coinsurance unless specified copay. The plan list says Primary care office visit ... copay; Specialist office visit ... 60 copay; Urgent care ... 75 copay; Emergency room copay waived if admission. We need apply office visit copay without deductible? Typically copay services not subject to deductible, but plan says copays do NOT credit deductible. Member cost share: copay flat. For office visits, member pays copay, no deductible? Yes. Preventive no cost share.

Need process.

Initial:
A: ded bal 904.50, oop bal 904.50
B: 0,0
C: 0,0
D:0,0
Family ded 904.50 oop 904.50.

Need account embedded: For in-network claim, deductible threshold = min(individual remainder, family remainder). Individual remainder = 1500 - member ded bal. Family remainder = 3000 - family ded bal. Deductible applied = lesser of allowed and that room. If member individual met? If min = 0? The individual threshold maybe met if member balance >=1500 OR family balance >=3000. The applicable remainder is min. Since family ded currently 904.50, family rem 2095.50; A ind rem 595.50. For A in-net claims until A ded reaches 1500, deductible_applied = min(claim allowed, 595.50 etc) until A met. But family rem higher.

For C,D,B with individual 0, in-net individual rem 1500 each; family rem initially 2095.50, so apply min(1500, family rem). If family rem <1500, family remainder limits for all; embedded individual can satisfy individual on own, but no member reaches coinsurance until? Actually embedded means individual satisfies individual deductible on their own; family deductible also satisfied once total family credits reach family amount, whichever comes first. Deductible_applied is lesser of allowed and room left under threshold: in-network = smaller of member individual remainder and family remainder. So yes if family remainder less than individual, total family credits limit.

Copays don't credit deductible; copays credit OOP only.

Need process line by line carefully, including OOP max caps. For member_responsibility = deductible_applied + copay + coinsurance? But OOP max can cap member responsibility. Need apply OOP max per member and maybe family? The OOP max is ceiling on member cost share. In-network individual 6000, out-of-network individual 12000? But plan says OOP individual in-network 6000, family 12000, individual OON 12000. Once member reaches OOP max plan pays 100% for covered services. For family? Need embedded OOP? It says family OOP 12000. Family OOP also ceiling? We need likely apply individual and family OOP max. Since all amounts under maybe less than 6000 individual? Some large. Family total could exceed 12000. Need determine OOP cap: Once a member reaches OOPM plan pays 100% allowed for covered services. Family OOP max means if family total reaches 12000, all members covered? Need likely apply family OOP too. But plan doc says Out-of-pocket maximum individual and family. Once a member reaches out-of-pocket maximum the plan pays 100% ... for remainder. For family, perhaps when family OOP max met, all members covered 100%. We need apply family OOP to all in-network covered services? The plan says family 12000. Usually embedded OOP: individual OOP max and family OOP max; once family OOP reached all covered. Need implement. But note OON individual OOP 12000, family? Family in-network 12000. Out-of-network claims credits to family OOP? It says OON claims credits still accumulate to member balance and family balance. The family OOP max maybe 12000 in-network, but OON thresholds higher. Family OOP can be reached by any member cost share. Need cap in-network claims at individual 6000 and family 12000? This could matter.

Let's compute all.

First line 1: Claim1 A specialist office in-net. Allowed 294.03. Service specialist office visit -> copay 60.00. Copay no deductible. Member responsibility = 60 (subject OOP cap). OOP balance A initially 904.50. Adding 60 => 964.50. Family OOP +60 => 964.50. Deductible no credit, so A ded remains 904.50, family ded remains 904.50. Plan paid = allowed - member resp = 234.03. claim_1 components not asked, but affects accum.

Line2 Claim2 C primary office in-net. Allowed 197.39. Copay 30. C OOP 0 -> 30. Family OOP 964.50->994.50. Deductible no credit? Copay does NOT credit deductible. So C ded 0, family ded unchanged. Plan paid 167.39.

Line3 Claim3 D inpatient admission with surgery in-net. Allowed 11804.80. Service not copay. Subject to deductible and coinsurance. At this point:
A ded 904.50, family ded 904.50, D ded 0, C 0.
Family ded balance 904.50, family remainder = 2095.50.
D individual remainder = 1500 - 0 = 1500.
In-network applicable room = min(1500, 2095.50) = 1500.
Deductible_applied = min(11804.80, 1500) = 1500.00.
Then coinsurance base = allowed - deductible_applied = 10304.80. Coinsurance 20% = 2060.96.
Member responsibility before cap = 1500 + 2060.96 = 3560.96.
OOP D currently 0, individual OOP max 6000, not reached. Family OOP before 994.50, after adding 3560.96 = 4555.46 below 12000. So no cap.
Update D ded 0->1500. Family ded 904.50+1500=2404.50.
D OOP 0->3560.96. Family OOP 994.50->4555.46.
Plan paid = 11804.80 - 3560.96 = 8243.84.
Check family ded rem after line3 = 595.50. Family OOP rem = 7444.54.

Line4 Claim4 C outpatient endoscopy in-net. Allowed 715.51.
Before line4: C ded 0, family ded 2404.50 (rem 595.50), C OOP 30, family OOP 4555.46.
C individual rem = 1500. Family rem = 595.50. In-net applicable room = min(1500, 595.50)=595.50.
Deductible_applied = min(715.51, 595.50)=595.50.
After deductible, coinsurance base = 120.01. Coinsurance 20% = 24.002 -> 24.00 (round half up). Member responsibility = 595.50 +24.00 = 619.50. (No copay). C OOP 30->649.50. Family OOP 4555.46+619.50=5174.96.
Update C ded =595.50. Family ded = 2404.50+595.50=3000.00. Family deductible satisfied after line4.
Plan paid = 715.51 - 619.50 = 96.01.
Claim4 originally on books components: ded_applied 595.50, copay 0, coinsurance 24.00, member 619.50, plan 96.01. But later voided line15, so final components 0. Need compute accumulators with void later.

Line5 Claim5 D inpatient admission in-net. Allowed 14614.81.
Before line5:
D ded 1500 (individual met), family ded 3000 (met). For in-network, applicable remainder = min(D individual rem = 0, family rem=0)=0. So deductible_applied=0.
Coinsurance base = allowed 14614.81. Coinsurance 20% = 2922.962 -> 2922.96.
Member resp = 2922.96.
D OOP before 3560.96 + 2922.96 = 6483.92. This exceeds individual OOP max 6000. Need cap at 6000. The plan pays 100% after member reaches OOPM. For this claim, if prior OOP = 3560.96, remaining room under individual OOP = 6000 - 3560.96 = 2439.04. So member responsibility should be min(coinsurance, remaining individual OOP) = 2439.04. Then after claim, D OOP reaches 6000. But also family OOP? Family before 5174.96. If member resp 2439.04, family OOP after 7614.00 below 12000. No family cap. Need choose cap individual 6000. So coinsurance amount? The claim's coinsurance amount on books should be what? If OOP cap limits member responsibility, how allocate? Member_responsibility = deductible_applied + copay + coinsurance_amount, with coinsurance reduced by OOP cap? Yes coinsurance_amount should be member cost after deductible before OOP cap maybe 2922.96, but member_responsibility capped to 2439.04. The required keys include deductible_applied, copay, coinsurance, member_responsibility, plan_paid. We must ensure member_responsibility + plan_paid = allowed. If member_resp = 2439.04 and planned paid = 12175.77, but coinsurance_amount could be 2922.96 (not summing). Hmm need define components. The task says "member_responsibility plus plan_paid equals allowed amount of the claim being reported". It does not necessarily require member_resp = deductible_applied + copay + coinsurance? But generally it does? We need report components. For cap, likely coinsurance_amount should be the actual coinsurance member pays after OOP cap, not initial calculated? Need think. The "cost share" components: deductible_applied, copay_amount, coinsurance_amount. Member responsibility is sum of those, but OOP max caps total member responsibility; how to reflect? In many ledgers, coinsurance_amount is the amount of coinsurance charged, then member_responsibility is min(total, OOP room), but then sum mismatch. The required "claim_4_member_responsibility, claim_4_plan_paid, claim_4_deductible_applied, claim_4_copay_amount, claim_4_coinsurance_amount" maybe they expect coinsurance after cap? Let's parse.

They say:
- member_responsibility plus plan_paid equals allowed amount.
- claim components maybe deductible_applied, copay, coinsurance. Usually member_responsibility = deductible_applied + copay + coinsurance, but OOP cap can make plan paid 100% after OOPM. To maintain, if OOP cap applies, coinsurance_amount should be the amount member actually pays as coinsurance, and deductible same. Then member_resp=ded+coinsurance. The initial calculated coinsurance is reduced. We'll adopt that: coinsurance_amount = member_responsibility - deductible_applied - copay after applying OOP cap. Need ensure plan_paid=allowed - member_resp. But if deductible_applied is still 0, coinsurance=2439.04? Let's see line5: ded0, copay0, member resp capped 2439.04, so coinsurance_amount =2439.04. Plan paid=12175.77. This seems right: actual member coinsurance after OOP max.

However would deductible_applied maybe also be reduced by OOP cap? No, deductible was 0. In a claim with deductible credited and OOP cap less than deductible? Actually if member has OOP room less than deductible_applied+cost, the deductible still might be credited? Hmm OOP max caps member responsibility. Usually deductible amounts also count toward OOP; if OOP max reached, no member responsibility, but deductible credit possibly? The plan says plan pays 100% of allowed amount after OOP max; so it would cover even deductible. Claim components might have deductible_applied 0 if no member responsibility? But accumulator credit? Need bookkeeping. For our lines, probably no such. But line6 D after OOP max reached; all subsequent D in-network claims paid 100%, no member resp, deduct 0.

Need continue.

Line5 update:
D OOP cap applied: member resp 2439.04, D OOP reaches 6000. Family OOP 5174.96 + 2439.04 = 7614.00.
Deductible no change because 0. Plan paid = 12175.77.

We need ensure family OOP maybe should cap at family? no.

Line6 Claim6 D ambulatory surgery in-net. Allowed 5634.42.
Before: D OOP already 6000 (individual max reached). For in-network D, plan pays 100%, member resp 0. Deductible 0 (already met/no). Coinsurance 0. Plan paid 5634.42. Accumulators: D OOP unchanged 6000? Member resp 0; family OOP unchanged 7614.00. Deductible unchanged. So claim6 no accum. Not asked.

Line7 Claim7 B inpatient admission in-net. Allowed 20898.76.
Before: B ded 0, family ded 3000 (met). For in-network, B individual rem = 1500, family rem=0. Applicable room = min(1500, 0)=0. So deductible_applied=0.
Coinsurance base = 20898.76. Coinsurance 20% = 4179.752 -> 4179.75 (20% = 4179.752 -> round half up 4179.75? 0.752 -> 4179.75 since third decimal? Actually 20898.76*0.20 = 4179.752, rounds to 4179.75. Yes).
B OOP before 0, individual max 6000. Member resp = min(4179.75, 6000) = 4179.75 (below). Family OOP before 7614, add 4179.75 = 11793.75, below 12000. No family cap. So B OOP = 4179.75; family OOP 11793.75.
Plan paid = 20898.76 - 4179.75 = 16719.01.
Deductible no.
This claim will be VOID at line11. Need eventually unwind from accumulators.

Line8 Claim8 D inpatient admission OON. Allowed 17086.02.
Before line8:
D ded balance 1500 (from line3) still. D OOP currently 6000 in-network OOP? For OON, individual OOP max 12000. D has OOP balance 6000 (all in-network member resp). OON remaining OOP = 12000 - 6000 = 6000. Deductible: OON individual threshold 3000, measured against member's single deductible balance = 1500. Remaining OON deductible = 3000 - 1500 = 1500. Family ded 3000? OON claims not limited by family. Deductible_applied = min(17086.02, 1500) = 1500.00. This credits D deductible from 1500 to 3000, family deductible from 3000 to 4500? Wait DCredits accumulate to family balance; yes OON credits still accumulate to family balance? Addendum says "The credits an out-of-network claim generates still accumulate to the member's balance and to the family balance." So family ded +1500 -> 4500. Although family deductible already satisfied, family balance not capped at in-network family amount? It says balances are not capped at in-network amounts because OON thresholds higher; yes family balances can exceed 3000. So update family ded 4500.

After deductible, OON coinsurance base = 17086.02 - 1500 = 15586.02. Coinsurance 40% = 6234.408 -> 6234.41.
Member resp before OOP cap = 1500 + 6234.41 = 7734.41.
D OOP individual OON max 12000. D current OOP balance? We need track if D individual OOP balance includes both in and out? OOP individual in-network max 6000; OON individual max 12000. The "out-of-pocket balance" is running total of member_responsibility. Once reached OOP max? For OON, the individual threshold is 12000, and D balance currently 6000. Member resp min(7734.41, 12000-6000=6000) = 6000.00. Then D OOP reaches 12000. Plan pays rest = 17086.02 - 6000 = 11086.02. But wait deductible_applied 1500 plus coinsurance? If capped at 6000, actual coinsurance = 6000 - 1500 = 4500.00, not full 6234.41. Components: deductible_applied=1500.00, copay=0, coinsurance_amount=4500.00, member_resp=6000.00, plan_paid=11086.02.
Family OOP before 11793.75 + 6000 = 17793.75. This exceeds family OOP 12000. Does family OOP max apply to OON? Plan has Family (in-network) 12000; Individual OON 12000. There is no family OON. Family OOP max maybe for in-network only? The plan says Out-of-pocket maximum: Family (in-network) 12000. It may cap family OOP for in-network services, but here OON member OOP allowed up to 12000. The family OOP maximum is in-network; an OON claim shouldn't be capped by family in-network OOP? The addendum says family amounts are INN amounts; out-of-network claims measured against OON individual thresholds only; family amounts do not limit OON claim. That is specifically for deductible but likely also OOP family? It says "family amounts, which are in-network amounts, do not limit an out-of-network claim." So family OOP 12000 should not cap OON claim. Thus no family cap for line8. Family OOP balance can exceed 12000 due to OON; balances not capped at in-network family amount. So family OOP = 17793.75.

After line8 D OOP balance = 12000 (individual OON reached). D ded = 3000. Family ded =4500. Family OOP=17793.75.

Need mention later no line8 void. This affects future in-network claims for D: D OOP individual in-network max already exceeded, so in-network claims for D paid 100%? Actually once member reaches OOP max, plan pays 100% for covered services for remainder. Which OOP max? D reached OON individual 12000. Since OOP balance 12000, definitely above in-network individual 6000, so D has reached all OOP max. So future D claims pay 100% (in and out?) likely yes. Deductible no more for D; D ded 3000.

Line9 Claim9 A primary care office in-net. Allowed 156.47.
Before line9: A ded 904.50, A OOP 964.50 (after line1; no family cap). Family ded 4500, family OOP 17793.75. In-network office copay 30. Copay no deductible; credits OOP. A OOP current 964.50 +30 = 994.50, below 6000. Family OOP +30 = 17823.75. Even family OOP max in-network? Wait family OOP exceeded due OON D; family OOP balance is >12000. If family OOP max 12000 is reached, for future in-network claims plan pays 100%? Hmm important. We need decide whether family OOP max applies after family balance exceeded 12000 due OON. The addendum says "out-of-network claims are measured against the out-of-network individual thresholds only; the family amounts, which are in-network amounts, do not limit an out-of-network claim. The credits an out-of-network claim generates still accumulate to the member's balance and to the family balance." Then later: "the balances are not capped at the in-network amounts." So family OOP balance can go above 12000. Now for subsequent in-network claims, family OOP max 12000 has been met. Does that mean all remaining in-network claims are paid 100%? The plan says "Once a member reaches the out-of-pocket maximum the plan pays 100% ...". Family OOP max: once family reaches, all members? Usually yes. But if family OOP max was exceeded by OON claims, would that cause in-network claims to be paid 100%? The family amount is an in-network amount; if total family OOP credits >12000, the family OOP max is satisfied. But the addendum says "family amounts do not limit an out-of-network claim" and balances not capped. It doesn't say family OOP max is not triggered. Could be triggered, causing all future in-network cost share waived. This is significant.

Need infer from plan document and accumulators. The plan doc: Out-of-pocket maximum Individual (in-network) 6000, Family (in-network) 12000, Individual OON 12000. Once a member reaches the out-of-pocket maximum the plan pays 100%... It states "Once a member reaches the out-of-pocket maximum" perhaps individual, not family. But family OOP max is listed. In family plans, when family OOP reached, all covered members have no cost share. The harness glossary says "Out-of-pocket maximum (OOPM): the ceiling on member cost share for the plan year. Once reached, the plan pays 100% of the allowed amount for covered in-network services." Hmm glossary says "ceiling on member cost share for the plan year. Once reached, the plan pays 100% of the allowed amount for covered in-network services." It mentions out-of-network? But plan doc specific: Once a member reaches OOP max plan pays 100% for covered services remainder. Family OOP max is likely relevant.

If family OOP max is met, then for all remaining covered in-network services, no member cost share. But what about copays? OOP max includes copays, so yes waive all cost share after family OOP reached. Here line8 D OON made family OOP exceed 

We are asked to adjudicate a series of claims in order, each updating accumulators, and then report specifically for Claim 4 (the fourth claim, for A, out-of-network diagnostic study). Also report ending accumulators after all claims are processed.

We are given starting accumulators before claim 1:
- A: deductible 900.00, OOPM 900.00
- B: deductible 0.00, OOPM 0.00
- Family deductible: 900.00, family OOPM: 900.00

Plan details:
- In-network deductible: individual 1500, family 3000, embedded.
- Out-of-network deductible: individual 3000 (but note: "In-network and out-of-network deductible credits accumulate to a SINGLE member deductible balance. The amount above is the threshold that balance is measured against when the service is out-of-network." So there's one member-level deductible accumulator that gets credits from both in- and out-of-network services. The threshold for whether it is met depends on the network status of the service. For in-network, the threshold is 1500; for out-of-network, it's 3000. For family deductible, the family threshold for in-network is 3000, but for out-of-network? The plan document doesn't specify an out-of-network family deductible. It says "Family (in-network) 3000.00" and "Deductible Out-of-network (individual) 3000.00". No separate family OON deductible mentioned. It says: "In-network and out-of-network deductible credits accumulate to a SINGLE member deductible balance. The amount above is the threshold that balance is measured against when the service is out-of-network." That applies to the individual-only. For family deductible, presumably it's the in-network family deductible amount that is used as the family threshold, and out-of-network claims also credit that same family accumulator? The document says "Family (in-network) 3000.00" under Deductible. There's no mention of a separate out-of-network family deductible. And it says: "In-network and out-of-network deductible credits accumulate to a SINGLE member deductible balance." That's for member-level. For family, they likely use the same family deductible accumulator and threshold (3000) regardless of network? But the plan says "Family (in-network)" only. In many real plans, the family deductible for OON might be double, but here only in-network is specified. The document's wording: "Family (in-network) .................... 3000.00". It doesn't list an out-of-network family deductible. So I think the family deductible applies only for in-network services? However, the principle of embedded deductible: each member's own deductible credits also count towards the family deductible. For out-of-network services, those credits count toward the member's single deductible balance (which is measured against OON threshold 3000 for OON services). But do those credits also count toward the family deductible? The plan says "In-network and out-of-network deductible credits accumulate to a SINGLE member deductible balance." That implies there is only one member balance, so credits from OON services also go to that balance. Does that balance also contribute to the family deductible? The family deductible is described only for in-network, but typically in an embedded plan, any member's deductible credits (from covered services) count toward the family deductible. I'd assume that OON services also count toward the family deductible accumulator, and the family deductible threshold is 3000 for in-network; but for OON services, the family deductible might not apply because family deductible is listed only under in-network. However, the plan does not explicitly say that OON services are excluded from family deductible accumulation. The plan says "Deductible: Individual (in-network) 1500.00, Family (in-network) 3000.00, Structure: EMBEDDED". It doesn't mention family out-of-network. In practice, many plans have a single family deductible that applies to both in and out-of-network, but with OON having a higher individual threshold. But here it's ambiguous. I'll look at the exact wording: "In-network and out-of-network deductible credits accumulate to a SINGLE member deductible balance. The amount above is the threshold that balance is measured against when the service is out-of-network." So the SINGLE member deductible balance is used for both thresholds. That balance is increased by both in-network and out-of-network credits. Then, for a claim, if in-network, the plan checks if the member's deductible balance has met the in-network individual threshold (1500) and the family deductible (3000) as per embedded rules. If out-of-network, it checks if the member's balance has met the out-of-network individual threshold (3000) and presumably also the family deductible? But the family deductible is labeled "Family (in-network)", so maybe OON services don't need to meet family deductible? Or maybe the family deductible only applies for in-network services; for OON services, only individual deductible applies? That would be odd. Typically, the family deductible is an aggregate limit for the family, and if a member goes OON, the family deductible still applies but with a higher individual OON deductible. Since the plan document does not specify an OON family deductible, and calls the family deductible "in-network", it could mean that the family deductible only applies for in-network services. Out-of-network services might not count toward the family deductible and might only be subject to the individual OON deductible. But the phrase "In-network and out-of-network deductible credits accumulate to a SINGLE member deductible balance" suggests that both types of claims credit the same member balance, which then counts toward the family deductible if they are in-network? That seems inconsistent. I'll check the rest of the plan: no mention of family OON deductible. I think the safest interpretation is that the family deductible amount applies only to in-network services. For out-of-network services, the member must satisfy the individual out-of-network deductible (3000) and the family deductible does not apply (or it's only the in-network family deductible that doesn't affect OON). However, the member deductible balance is a single balance that is credited with both in- and out-of-network claims. So when processing an OON claim, we consider the member's current deductible balance and check if it meets the individual OON threshold of 3000. Also, what about family OOPM? Family OOPM in-network is 12000, out-of-network individual OOPM is 12000. Again, family OOPM is only in-network. So OON claims might only count toward individual OOPM, not family OOPM? Need to interpret. I'll read the plan document literally: For deductible, it lists Individual (in-network) 1500, Family (in-network) 3000, Out-of-network (individual) 3000. So OON individual deductible is separate threshold, but the credits are pooled. For OOPM: Individual (in-network) 6000, Family (in-network) 12000, Individual (out-of-network) 12000. So OON OOPM per individual is 12000. There's no family OON OOPM. So likely OON services are only subject to the individual limits, not family limits. But the single member deductible balance and member OOPM balance might be separate? Or they might pool OOPM as well: "Copays always credit the out-of-pocket maximum." And OOPM for in-network individual is 6000, out-of-network individual is 12000. The plan doesn't say whether OON cost-sharing counts toward the in-network OOPM or just the OON OOPM. Typically, plans have separate OOPM accumulators for in-network and out-of-network. But here they list them separately, so likely they are separate tracks. However, the plan says: "Once a member reaches the out-of-pocket maximum the plan pays 100% of the allowed amount for covered services for the remainder of the plan year." It doesn't specify which OOPM, but likely it's the relevant one based on network. So for OON services, the member must reach the OON individual OOPM of 12000 for the plan to pay 100% for OON services. In-network OOPM is 6000 individual, 12000 family. So they are separate. Also, cost-sharing for OON services does not count toward in-network OOPM, probably. But does in-network cost-sharing count toward OON OOPM? Usually they are separate. So I'll assume separate OOPM accumulators: one for in-network (with individual and family limits), and one for out-of-network (individual only, since no family listed). But the plan says "In-network and out-of-network deductible credits accumulate to a SINGLE member deductible balance" but does NOT say that for OOPM. So OOPM accumulators are likely separate for in-network and out-of-network. The starting OOPM values are 900 for A, 0 for B, and family OOPM 900. Given that they started with these, they must be the in-network OOPM accumulators? The problem statement: "FAMILY ACCUMULATORS as of the moment before Claim 1 A (subscriber) deductible 900.00 out-of-pocket 900.00 B (spouse) deductible 0.00 out-of-pocket 0.00 Family total deductible 900.00 out-of-pocket 900.00". It doesn't specify in-net vs out-of-net for these accumulators. Presumably, the accumulators given are the ones that apply based on the service type, or they are the single member deductible balance (which is shared) and the OOPM could be the in-network OOPM (since family OOPM is listed). Since they only gave one set, likely the deductible accumulator is the single balance used for both, and the OOPM accumulator is the in-network OOPM (and maybe OON OOPM is separate and starts at 0 for A and B? They didn't give OON OOPM accumulators. The problem statement didn't specify any out-of-pocket accumulators for out-of-network. So we might need to infer that the given OOPM accumulators are the in-network ones, and for OON claims, we need to track a separate OON OOPM for each member. That seems messy. Alternatively, perhaps the plan has a single OOPM that applies regardless of network, with individual limits that differ by network. For example, a member's in-network OOPM is 6000, and any cost-sharing (including OON) counts toward that, but once they hit 6000, the plan pays 100% for in-network only, while for OON they still need to satisfy the 12000 OON limit. But typical PPACA plans have unified OOPM but OON can have higher limits. Actually, the out-of-pocket maximum is usually a single total for all covered services, but plans can have a higher OOPM for out-of-network services. The member's total out-of-pocket spending counts toward the OOPM, but the OON limit is higher. So there could be one accumulator that is compared to both in-network and out-of-network thresholds. But the plan lists them as separate: Individual (in-network) 6000, Family (in-network) 12000, Individual (out-of-network) 12000. That suggests that the in-network OOPM (6000 individual, 12000 family) is a separate limit that only in-network cost-sharing counts toward, and the OON OOPM (12000 individual) is a separate limit that only OON cost-sharing counts toward. That would mean we need to track two sets of OOPM accumulators: one for in-network spending per member and family, and one for out-of-network spending per member (maybe no family). The problem statement gave initial OOPM for A=900, B=0, family=900. These likely refer to the in-network OOPM accumulators, as the family OOPM is only in-network. So for OON claims, we may need to track a separate OON OOPM accumulator for each member, starting at 0. That seems like a lot to infer. Let's look for clues in the plan document: "Copays always credit the out-of-pocket maximum." Which OOPM? Probably the one relevant to the service's network. So a copay for an in-network visit credits the in-network OOPM; an OON service may not have copays but if it did, it would credit OON OOPM. The document doesn't explicitly say OOPM accumulators are separate, but it lists separate limits. I think the safe approach is: deductible is a single accumulator per member (and family), with different thresholds based on network. OOPM is separate per network type (in-network OOPM accumulator per member/family, and out-of-network OOPM accumulator per individual, no family). The given initial accumulators include a family OOPM, so that must be the in-network OOPM accumulator for family. So A's in-network OOPM is 900, B's is 0, and family in-network OOPM is 900. Out-of-network OOPM for A and B start at 0. I'll adopt that.

Now process claims.

Claim 1: 2026-05-05, A, out-of-network specialist procedure, OON, billed 4440, allowed 2400.
Network: out-of-network. So subject to deductible (individual OON threshold 3000) and coinsurance 40% member after deductible. Also, since OON, there may be no family deductible threshold? I'll assume family deductible does not apply for OON services; only individual OON deductible. But the single member deductible balance is used. So A's current deductible balance is 900 (from starting). Need to see if he's met the OON deductible threshold of 3000. He has only 900, so he must pay more until his deductible balance reaches 3000. For OON, the deductible threshold is 3000. So he needs to apply the allowed amount toward his deductible balance until it hits 3000. He currently has 900, remaining to meet OON deductible: 3000 - 900 = 2100. So of the 2400 allowed, 2100 will go to deductible, leaving 300 to be subject to coinsurance. But wait: the plan says "The amount above is the threshold that balance is measured against when the service is out-of-network." So if the member's deductible balance is < 3000, the plan won't pay anything until the deductible balance reaches 3000. So on this claim, the member pays the allowed amount up to the amount that brings his deductible balance to 3000. That would be 2100 deductible, then coinsurance on the remaining 300. Member coinsurance 40% of 300 = 120. So total member responsibility = 2100 + 120 = 2220. Plan pays the rest: allowed - member = 2400 - 2220 = 180? Actually plan pays 60% of the 300 = 180. So plan paid = 180. But check: if the member has already accumulated 900 deductible balance, then after applying 2100, his new deductible balance becomes 3000, meeting the OON threshold. Then coinsurance on the 300. So member responsibility = deductible applied 2100 + coinsurance 120 = 2220. Plan paid = 180. But is the allowed amount limited by OON? The plan says member cost share is from allowed amount; balance billing above allowed is not member responsibility for in-network, but for out-of-network, they can balance bill. The question doesn't ask about balance billing, only member_responsibility and plan_paid from the allowed amount. So that's fine.

Now, what about accumulators? Deductible: the member's deductible balance increases by the amount of allowed that was applied to deductible. The plan says "In-network and out-of-network deductible credits accumulate to a SINGLE member deductible balance." So the member's single deductible balance is increased by the amount that counts toward deductible. For this claim, the amount that goes to deductible is 2100. After claim 1, A's deductible balance = 900 + 2100 = 3000. The family deductible also accumulates: since the plan has embedded structure, and any member's deductible credits also go toward the family deductible. Does OON claim's deductible credit count toward family deductible? The family deductible is labeled "Family (in-network)". It doesn't explicitly say OON credits count toward family deductible. But the single member deductible balance is the same for both. The family deductible threshold is only for in-network services. However, if OON credits also credit the family deductible accumulator, then the family deductible balance would increase by the same amount. Given the "SINGLE member deductible balance", and the embedded structure, likely all deductible credits (in- and out-of-network) count toward both the member's balance and the family balance. The family deductible is a pooled accumulator. I'll assume that OON deductible credits also count toward the family deductible. Because otherwise, the phrase "In-network and out-of-network deductible credits accumulate to a SINGLE member deductible balance" suggests that the member balance is shared, but the family balance might also be shared? I think it's typical that the family deductible accumulates from all covered expenses regardless of network. The plan doesn't say OON services are excluded from family deductible. The label "Family (in-network)" might just mean the family deductible amount applies only to in-network services, but the accumulation of credits might still happen from OON. The confusion: I need to decide. Let's read the plan again: "Deductible Individual (in-network) ................ 1500.00 Family (in-network) .................... 3000.00 Structure EMBEDDED — an individual satisfies the individual deductible on their own; the family deductible is also satisfied once total family credits reach the family amount, whichever comes first. Out-of-network (individual) ............ 3000.00 In-network and out-of-network deductible credits accumulate to a SINGLE member deductible balance. The amount above is the threshold that balance is measured against when the service is out-of-network." It does not mention an out-of-network family deductible. So for a claim that is out-of-network, the family deductible might not be considered; i.e., only the individual OON deductible matters, and the family deductible does not need to be met for OON claims. But the phrase "total family credits" implies that credits from all family members count toward the family deductible. It doesn't specify in-network only. So I think the family deductible accumulator is single, and credits from any claim (in or out) apply to it. The threshold for the family deductible is 3000, but that threshold likely only matters for in-network claims. For out-of-network claims, the family deductible threshold is irrelevant because the OON individual deductible is higher (3000). However, for an in-network claim, the member must have met both the individual in-network deductible (1500) and the family deductible (3000) in an embedded way. So OON claims would increase both the member's balance and the family balance. I'll go with that: family deductible accumulates from all claims. Then after claim 1, family deductible balance becomes starting 900 + 2100 = 3000. So family deductible is met.

OOPM: On claim 1, member cost-sharing (2220) counts toward OOPM. But which OOPM? For out-of-network services, there is an individual OON OOPM of 12000. I think the member's OON OOPM accumulator is separate from the in-network one. So we need to track two OOPM per member: in-network OOPM and out-of-network OOPM. Then the family OOPM is only for in-network. So for claim 1, A's OON OOPM accumulator increases by 2220. Starting OON OOPM for A was presumably 0. So after claim 1, A's OON OOPM = 2220. In-network OOPM for A remains 900. Family OOPM (in-network) remains 900. Also, does OON cost-sharing count toward the in-network OOPM? Typically no, separate. So no change to in-network OOPM.

Now claim 2: 2026-05-21, B (spouse), in-network outpatient imaging, allowed 1300. In-network. So subject to in-network rules: deductible (individual 1500, family 3000), coinsurance 20% after deductible. Copay? Not applicable; it's imaging, not an office visit. So it goes to deductible and coinsurance.

Current accumulators:
- A deductible balance: 3000 (after claim1)
- B deductible balance: 0 (starting)
- Family deductible balance: 3000 (already met)
- A in-network OOPM: 900
- A out-of-network OOPM: 2220
- B in-network OOPM: 0
- B out-of-network OOPM: 0 (assume)
- Family OOPM (in-network): 900

For claim 2, B is the member, in-network. Since family deductible is already met (3000), the family deductible condition is satisfied. B's individual in-network deductible is 1500. B has 0 so far. So B must satisfy his individual deductible up to 1500. However, because of embedded structure, onc

We need answer task. Need parse roster, measure QM-CBP. Need place each member. Need output JSON with counts and lists.

We must carefully evaluate each member for eligibility, exclusions, numerator. We need note specs.

Measure year 2026. Eligible population: age 18-85 as of 2026-12-31. Event: at least one outpatient encounter with hypertension diagnosis I10 on or between 2026-01-01 and 2026-06-30. Encounter after 2026-06-30 does not establish event. Continuous enrollment: enrolled full measurement year with no more than one gap up to 45 days. A gap longer than 45 days, or two or more gaps any length, removes.

Numerator: most recent outpatient BP reading taken on or after date of qualifying hypertension encounter and on or before 2026-12-31 is below 140 systolic and below 90 diastolic. Both components below threshold. ED or inpatient readings do not count and skipped. If no qualifying reading exists, denominator non numerator.

Exclusions: E1 ESRD N18.6 or Z99.2 any time before/at 2026-12-31. E2 pregnancy any O00-O9A code during measurement year. E3 hospice/palliative any time during measurement year. E4 died during measurement year.

Need determine statuses.

Let's list members.

MEMBER 71011. DOB 1965 => age 61. Enrollment continuous no gaps. Event: office I10 2026-01-06 yes between. Exclusions none. Numerator: most recent outpatient BP after qualifying date and <= year. Office BPs: 1/6 122/76, 4/28 J06 132/70, 6/6 I10 133/87. Most recent outpatient = 6/6 133/87, below 140 and below 90? 87<90 yes. Compliant. 

71012. Age 48. Enrollment continuous. Event: office I10 3/27 yes. Exclusions none. BP readings: 3/27 142/77, 6/14 141/79, 7/3 127/94 (office but diagnosis E78.5, doesn't matter for BP reading? Spec numerator says outpatient blood pressure reading, no diagnosis requirement. Yes any outpatient reading after qualifying date. Most recent outpatient BP = 8/6 132/81. Below 140 and below 90 yes. Compliant. Need note reading 7/3 systolic 127 diastolic 94 not both below, but 8/6 132/81 okay. Compliant.

71013. Age 44. Enrollment 1/1-6/2, 7/9-12/31. One gap? Actually 1/1-6/2 then 7/9-12/31: gap from 6/3 to 7/8 inclusive 36 days. One gap <=45. Continuous enrollment full? It says enrolled full measurement year with no more than one gap up to 45 days. This qualifies (one gap 36). Event: at least one outpatient encounter with I10 on/between 1/1-6/30. Encounters: 5/20 inpatient S52 no; 7/7 inpatient I10 after June 30 and inpatient not outpatient; 7/23 office I10 after June 30. No outpatient I10 on/before 6/30. So not_eligible due no event. Need exclusions? none. Enrolment okay. Age okay. Thus not_eligible.

71014. Age 70. Enrollment 1/1-6/23; 7/20-12/31. One gap 26 days. Eligible. Event: office I10 3/12 yes. Exclusions? none. Numerator: most recent outpatient BP on/after 3/12 to year end. Office BPs: 3/12 127/89 below both (systolic 127<140, dia 89<90 yes); 5/7 125/102 dia 102; 6/6 119/92 dia 92. Most recent = 6/6 119/92, diastolic 92 not below 90. Not numerator. So non_compliant. Need confirm 3/12 data 127/89 qualifies? diast 89<90 yes. "below 90" means 89 yes. Good. But most recent is 6/6, not controlled. non_compliant.

71015. DOB 2009 => age 17 on 12/31. Not eligible age. Enrollment has two gaps? irrelevant. Event irrelevant. Exclusions maybe? no. not_eligible. Need ensure age 17 not 18. yes not_eligible.

71016. Age 70. Enrollment 1/1-5/24; 7/11-12/31. One gap 47 days. Spec says gap longer than 45 removes. So not eligible due enrollment (no more than one gap up to 45 days). Event office I10 6/12? This is during gap and after 5/24, but encounter after? Date 6/12 is during gap but encounter could occur; qualifying event date on/between Jan 1-Jun30 yes office I10. However enrollment fails. not_eligible. Exclusions: pregnancy prior year not measurement year, not E2. Only prior year O26.899 (O code) prior year not during measurement year. Exclusions evaluated before numerator only for eligible population; member not eligible due enrollment. Status not_eligible. 
Need think: "Exclusions are evaluated before the numerator, and only for members who are in the eligible population: a member who fails age, event, or enrolment is not_eligible even if an exclusion is also documented." So yes not_eligible.

71017. Age 48. Enrollment 1/1-4/22; 6/1-12/31. One gap 39 days <=45. Event: office I10 3/18 yes. Exclusions none. Numerator: BPs after 3/18: 3/18 143/80 (systolic high), 10/19 134/85 (both below). Most recent = 10/19 134/85 compliant. 
Need ensure qualifying encounter date 3/18; the BP same day counts? "on or after date" yes. Most recent is 10/19. Compliant.

71018. Age 70. Enrollment 1/1-6/1; 7/19-12/31. One gap? From 6/2 to 7/18 inclusive: 47 days? Let's calculate: June 2-30 = 29 days? Actually gap starts day after 6/1, through day before 7/19. Days absent: 6/2 through 7/18 inclusive. Jun 2-30 = 29 days (since 2-30 inclusive =29? 30-2+1=29), July 1-18 =18, total 47. Yes gap >45. Not eligible due enrollment. Event office I10 1/27 yes. But not_eligible. Exclusions none. not_eligible.

71019. Age 52. Enrollment 1/1-3/24; 5/6-12/31. One gap 42 days <=45. Event: office I10 6/14 yes (within Jan 1-Jun30). Exclusions none. Numerator: most recent outpatient BP on/after 6/14: only 6/14 151/80, systolic 151 not below 140. non_compliant. 

71020. Age 52. Enrollment continuous. Event: office I10 1/20 yes. Exclusions none. Numerator: BPs: 1/20 140/71, 6/2 158/80. Most recent 6/2 158/80 systolic high. 1/20 systolic 140 not below 140 (needs below 140), so even if most recent no. non_compliant. 

71021. Age 44. Enrollment continuous. Event: At least one outpatient encounter with I10 Jan-Jun. Encounters: 4/24 ED I10: Is ED "outpatient"? Spec says "outpatient encounter"; numerator specifically excludes ED or inpatient readings. For event, it says at least one outpatient encounter with a hypertension diagnosis (I10). Does ED count as outpatient? In many measures ED is not outpatient? Need parse. The spec: "Event: at least one outpatient encounter with a hypertension diagnosis (I10) on or between 2026-01-01 and 2026-06-30." ED visit is an emergency department visit, not office/outpatient? The numerator says "A reading taken in an emergency department or on an inpatient admission does not count..." It doesn't say ED cannot be qualifying event. "Emergency department visit" is generally an outpatient service? In payer ops, emergency department is often considered outpatient for claims, but quality measure office visits sometimes exclude ED. We need infer from given spec: It says "outpatient encounter with a hypertension diagnosis". It does not list ED as excluded for event, unlike numerator reading. ED visit is not inpatient, so it's outpatient. But some quality specs define outpatient as excluding ED. We need use supplied material. The measure says "A reading taken in an emergency department or on an inpatient admission does not count and is skipped when identifying the most recent reading." Did not say outpatient encounter excludes ED. Thus ED likely counts as outpatient encounter for event? Need evaluate carefully. It might be a trap: 71021 has ED I10 on 4/24 in window, then office I10 7/15 after window. If ED not outpatient for numerator reading, but likely is an outpatient encounter? Actually in health quality measurement, "outpatient" generally includes ambulatory visits and ED visits? Let's consider. The numerator reading excludes ED specifically, which implies ED would otherwise be an outpatient reading? It says "A reading taken in an emergency department or on an inpatient admission does not count and is skipped..." That suggests ED readings are not allowed. For the event (diagnosis) no exclusion of ED, so ED I10 can establish event? It might be "outpatient encounter" includes ED? The task likely expects to count ED? We need decide.

Measure QM-CBP Blood pressure control. Typically HEDIS requires "at least one outpatient visit with essential hypertension diagnosis" and ED visits may not count? Actually HEDIS? The spec provided doesn't say ED excluded in eligible event. We should follow supplied material exactly. It says outpatient encounter. ED is a type of outpatient encounter? In claims, place of service Emergency Room - Hospital is outpatient hospital. But "outpatient encounter" maybe not inpatient. I'd count as outpatient. However need see numerator excluding ED means it's not a qualifying BP reading even if outpatient? They explicitly skip ED readings. So members with only ED BP cannot use for numerator. But event can be established by ED I10 if outpatient? 

Let's read prompt exact: "Event: at least one outpatient encounter with a hypertension diagnosis (I10) on or between 2026-01-01 and 2026-06-30. An encounter after 2026-06-30 does not establish the event." It doesn't define outpatient. In roster, 71021 has ED visit 4/24 diagnosis I10. They might have included ED to test if ED counts as event and reading skipped. There is also office I10 7/15 after cutoff. If ED does not count as outpatient for event, no event before 6/30 => not_eligible. If ED counts, eligible. Then numerator: most recent outpatient BP reading (non-ED, non-inpatient) on/after qualifying hypertension encounter (4/24) and <= year. BP readings: ED 4/24 129/79 (skip), office 7/15 166/93, ED 9/9 134/75 (skip). Most recent non-ED outpatient = 7/15 166/93, systolic 166 diastolic 93 both high. Non_compliant. So the question is whether 71021 is not_eligible or non_compliant.

The task likely expects ED as outpatient encounter? Let's inspect wording: In numerator: "A reading taken in an emergency department or on an inpatient admission does not count and is skipped when identifying the most recent reading." For event, it says "outpatient encounter" and encounters in roster include "Emergency department visit". If they wanted ED to not establish event, they'd likely say "outpatient encounter" maybe not include ED? In healthcare, emergency department is often not "outpatient encounter" for quality measure? But "inpatient admission" is contrasted with outpatient. Let's use supplied definition. The measure spec explicitly says "emergency department or on an inpatient admission does not count" only for readings, not for the hypertension encounter. So ED visit with I10 should count as outpatient encounter. Roster says "Emergency department visit, diagnosis I10. BP 129/79." So event is established if ED is outpatient. I think yes. Then 71021 non_compliant. Need be consistent.

71022. Age 19. Enrollment continuous. Event: office I10 10/08 is after 6/30. No encounters before 6/30. So no event, not_eligible. But age 19. Not_eligible due event.

Now count all 12. Need careful statuses.

Let's enumerate possible:

71011: eligible? age yes, enrollment yes, event yes, no exclusions. Numerator yes. compliant.
71012: yes. compliant.
71013: no event (only inpatient before? no outpatient), enrollment ok. not_eligible.
71014: yes denominator. Numerator no. non_compliant.
71015: age 17. not_eligible.
71016: enrollment gap 47 >45. not_eligible. Note also event? not relevant.
71017: yes. compliant.
71018: gap 47 >45. not_eligible.
71019: yes. non_compliant.
71020: yes. non_compliant.
71021: need decide. If ED counts as event, denominator yes. Numerator no. non_compliant. If ED not event, not_eligible. We'll settle soon.
71022: no event before 6/30. not_eligible.

If 71021 non_compliant, denominator count: compliant members 71011, 71012, 71017 = 3. Non_compliant: 71014, 71019, 71020, 71021 = 4. Denominator = 7. Excluded = 0. Not_eligible: 71013, 71015, 71016, 71018, 71022 = 5. Total 12. Rate 3/7*100=42.857 -> round half up one decimal 42.9.

If 71021 not_eligible, denominator =6 (compliant 3, non_compliant 3), not_eligible 6. Rate 50.0.

Need determine likely expected. Let's consider measure "Blood pressure control in hypertension" maybe based on NCQA HEDIS CBP. HEDIS "outpatient visit" often includes ambulatory visits; ED visits? For HEDIS, "outpatient" includes "visits/encounters that occur in a variety of settings, including but not limited to..."; emergency room? Hmm HEDIS uses "outpatient visit" identified by specific visit type, ED visits may be not counted as outpatient for some events, but for "event/diagnosis" they may use "outpatient visits, telephone visits, e-visits, virtual check-ins?" Not likely ED. The given spec says "outpatient encounter" and roster explicitly labels "Emergency department visit". The spec only excludes ED for blood pressure reading, not diagnosis encounter. A test may be ensuring we don't skip ED for diagnosis. So yes likely ED counts for event.

But let's re-read: "Event: at least one outpatient encounter with a hypertension diagnosis (I10) on or between ...". An "emergency department visit" is often billed as outpatient facility, but in measure contexts, emergency department is not an outpatient encounter? Actually an ED visit is an outpatient encounter unless admitted. But many quality specs define "outpatient encounter" as excluding ED? Hmm.

Need maybe infer from intended word "outpatient" in the spec: "A reading taken in an emergency department or on an inpatient admission does not count and is skipped when identifying the most recent reading." If ED were not considered outpatient, they wouldn't need to say "emergency department" in numerator; they say ED because ED is outpatient but they want excluded. So for event, ED is outpatient and counts. Thus 71021 non_compliant.

Also consider 71013: Event: 5/20 inpatient, 7/7 inpatient I10, 7/23 office I10. No outpatient I10 on/before 6/30. But 7/7 inpatient I10 after 6/30 and not outpatient. not_eligible. Good.

Need check 71016: Enrollment gap >45. But events: office I10 6/12 during gap. They are not enrolled? In enrollment as rows: 2026-01-01 through 2026-05-24; 2026-07-11 through 2026-12-31. gap 47 days. Not eligible. It says "enrolled for full measurement year with no more than one gap of up to 45 days". This member not enrolled 5/25-7/10. Gap length 47. Thus not_eligible. Good.

Need check 71018 gap: 1/1-6/1; 7/19-12/31. Gap from 6/2 to 7/18 = 47. not_eligible. 

71015: two gaps any length, even though age 17 anyway. not_eligible age. Good.

Now exclusions: none in roster? Need check 71016 prior year pregnancy, not measurement year. No ESRD/hospice/death. So excluded = 0.

Need produce arrays of member IDs as strings. Order any. Counts match.

We should include only required keys. "denominator": 7, "numerator": 3, "excluded": 0, "not_eligible": 5, "rate": 42.9, "compliant_members": ["71011","71012","71017"], "non_compliant_members": ["71014","71019","71020","71021"], "excluded_members": [], "not_eligible_members": ["71013","71015","71016","71018","71022"].

Need ensure no extra keys. Fenced JSON only.

Before final, let's deeply assess potential edge cases.

Continuous enrollment: "with no more than one gap of up to 45 days. A gap longer than 45 days, or two or more gaps of any length, removes the member from the denominator." For 71015 age 17 not eligible anyway. For 71013 one gap 36 days, okay. For 71014 one gap 26 days okay. For 71016 one gap 47 >45 not eligible. For 71017 one gap 39 okay. For 71018 one gap 47 not eligible. For 71019 one gap 42 okay. Good.

Event criterion: at least one outpatient encounter with I10 on/between Jan 1 and June 30. Need check for all:
71011 1/6 office I10 yes.
71012 3/27 office I10 yes.
71013 no outpatient I10 before 6/30. Office 7/23 after cutoff. not_eligible.
71014 3/12 office I10 yes.
71015 office I10 1/9 yes but age not.
71016 office I10 6/12 yes in date range, but during enrollment gap. Enrollment not okay.
71017 3/18 office I10 yes.
71018 1/27 office I10 yes but enrollment not okay.
71019 6/14 office I10 yes.
71020 1/20 office I10 yes.
71021 4/24 ED I10 yes? 
71022 only office I10 10/08 after 6/30, no.

Numerator details:
- Most recent outpatient BP reading taken on or after the date of the qualifying hypertension encounter and on/before 12/31 is <140 systolic AND <90 diastolic.
- ED/inpatient reading does not count and skipped.

For each eligible:
71011: qualifying date 1/6. BPs after: 1/6 office 122/76, 4/28 office 132/70, 6/6 office 133/87. Most recent 6/6 133/87 controlled (<140, <90). compliant.
71012: qualifying date 3/27. BPs after: 3/27 142/77, 6/14 141/79, 7/3 127/94, 8/6 132/81. Most recent 8/6 controlled. Wait 8/6 132/81 <90 yes. compliant. But need "most recent outpatient BP reading" includes any office diagnosis, yes. The reading on 8/6 is after qualifying and controlled. 
71014: qualifying 3/12. BPs after: 3/12 127/89 controlled; 5/7 125/102; 6/6 119/92. Most recent 6/6 not controlled. non_compliant. Good.
71017: qualifying 3/18. BPs after: 3/18 143/80 not controlled; 10/19 134/85 controlled. Most recent 10/19. compliant.
71019: qualifying 6/14. BP same day 151/80 not controlled. non_compliant.
71020: qualifying 1/20. BPs after: 1/20 140/71 (systolic not below 140? "below 140" means 140 does not count). 6/2 158/80 not. non_compliant.
71021: qualifying 4/24 ED. BPs on/after: ED 4/24 skip, office 7/15 166/93, ED 9/9 skip. Most recent qualifying outpatient is 7/15 166/93 not controlled. non_compliant. Good.
 
Need consider 71013 not eligible due event, but if ED counts? It has inpatient 7/7 and office 7/23 after. no before.

Exclusions: 
- 71016 had O26.899 in 2025 (prior year). E2 is "Pregnancy (any O00-O9A code) during the measurement year." Prior year doesn't count. not exclusion. Also not eligible anyway.
- No ESRD, dialysis, hospice, death. 

Potential issue: O26.899 is an O code but prior year, as given. Good.

Rate calculation: numerator/denominator*100 = 3/7*100 = 42.857142857 -> one decimal half up = 42.9. If exact 42.857 rounds to 42.9. Yes.

Now, let's think if member 71021 ED encounter might not be "outpatient encounter" for event. Since this hinge, I'd like to be certain. The spec says "outpatient encounter" but not defined. However task status definitions from family says "not_eligible never enters eligible population (age, event, or enrolment)." In roster, encounter 71021 has "Emergency department visit" in "Encounters and results." The spec numerator explicitly says ED readings do not count. If the measure wanted ED visits not to count as outpatient encounter, they would probably say "A reading taken in an emergency department or on an inpatient admission does not count and is skipped" only for BP reading, not for diagnosis. Could be a deliberate distinction: emergency department visit is an outpatient encounter for diagnosis but blood pressure reading excluded due to not routine? Actually if an ED visit is outpatient, then event I10 yes. If they would not count ED for event, the phrase "outpatient encounter" is ambiguous but generally ED is not outpatient? Hmm.

Let's search memory: In HEDIS, "outpatient visit" can include "outpatient visits, observation visits, telephone visits, online assessments, ED visits..."? Wait HEDIS "Outpatient visits" typically define as "visits to a physician or other healthcare professional in an ambulatory setting, including an office visit, home visit, or outpatient clinic. Excludes inpatient and ED visits?" Need actual CBP: HEDIS CBP (Controlling High Blood Pressure) uses "outpatient visits" with a diagnosis of hypertension. It includes "outpatient visits (Outpatient Value Set)" and "telephone visits, e-visits, virtual check-ins" maybe not ED. Actually HEDIS measure "Controlling High Blood Pressure" (CBP) requires adults 18-85 who had at least one outpatient visit with a diagnosis of hypertension in the first six months. "Outpatient visit" is defined by HEDIS as any outpatient visit, not including ED? I think ED visits are not considered outpatient visits for HEDIS event? HEDIS differentiates "outpatient visit" from "ED visit" and "observation visit". In many HEDIS measures, "outpatient" includes "visits to a physician in an office or outpatient clinic," not ED or inpatient.

But this harness measure spec
