Aggregate family deductible, HDHP

**My Adjudication Process for Claim 1**

Alright, let's break down this claim. My primary objective here is to adjudicate a single claim against the provided plan document and member accumulators, ultimately producing a specific JSON output.

First, I need to thoroughly understand the plan details. This is a "Trinity HDHP 3200". The deductible structure is key: an individual in-network deductible of $3200.00 and a family in-network deductible of $6400.00. The plan document specifies an **AGGREGATE** structure, which means no coinsurance applies for *any* member until the *total family credits* reach the family deductible. Crucially, it states, "There is no individual deductible under this structure." This is a critical point I need to keep in mind – the family deductible takes precedence for coinsurance application. The out-of-pocket maximums are $7000.00 individual and $14000.00 family, both in-network. No copays are involved.

Before this claim, the member accumulators show:
*   Member deductible credited year to date: $0.00
*   Member out-of-pocket credited year to date: $0.00
*   Family deductible credited year to date: $4100.00
*   Family out-of-pocket credited year to date: $4100.00

Now, for Claim 1: It's an outpatient cardiac catheterisation, in-network, billed at $9880.00 and allowed at $5200.00.

My adjudication process begins with the deductible. Because this is an AGGREGATE plan, the family deductible of $6400.00 must be met before coinsurance kicks in. The family deductible has $4100.00 already credited, leaving $6400.00 - $4100.00 = $2300.00 remaining.

The allowed amount for the service is $5200.00. The member is responsible for the remaining family deductible, which is $2300.00. After applying this deductible amount, the remaining allowed amount available for coinsurance consideration is $5200.00 - $2300.00 = $2900.00.

Next, coinsurance. The plan states 10% member / 90% plan for in-network services after the deductible. So, the coinsurance amount is 10% of $2900.00, which equals $290.00.

My calculation for the total member responsibility for this claim is the deductible portion plus the coinsurance: $2300.00 (deductible) + $290.00 (coinsurance) = $2590.00.

I then need to check this against the Out-of-Pocket Maximums (OOPM). The member's individual OOPM starts at $0.00 and is now $2590.00 after this claim. This is well below the individual OOPM of $7000.00. The family OOPM, which started at $4100.00, will now be $4100.00 + $2590.00 = $6690.00. This is also below the family OOPM of $14000.00. So, no OOPM limitation is triggered.

The plan's payment for this claim is the allowed amount minus the member's responsibility: $5200.00 - $2590.00 = $2610.00.

Now, for the accumulator updates. This is where I need to be meticulous.
The "ending\_member\_deductible" is tricky because the plan states "no individual deductible under this structure." However, the plan also mentions that "In-network and out-of-network deductible credits accumulate to a SINGLE member deductible balance." Since $2300.00 was applied towards the family deductible (which the member is responsible for meeting), and this balance *does* contribute to a "member deductible balance," I will update the member deductible accumulator to $2300.00. The initial member deductible was $0.00, and $2300.00 was applied.
The "ending\_member\_oopm" will be the member's OOPM after this claim, which is $2590.00 (starting at $0.00 and adding the member's $2590.00 responsibility for this claim).

I've re-checked my calculations:
*   Allowed amount: $5200.00
*   Deductible applied: $2300.00
*   Remaining for coinsurance: $2900.00
*   Coinsurance (10%): $290.00
*   Total Member Responsibility: $2300.00 + $290.00 = $2590.00
*   Plan Paid: $2900.00 - $290.00 = $2610.00
*   Total of Member Responsibility and Plan Paid: $2590.00 + $2610.00 = $5200.00 (matches allowed amount).

The prompt requires specific fields for the JSON output:
*   `member_responsibility`: $2590.00
*   `plan_paid`: $2610.00
*   `deductible_applied`: $2300.00 (this is the portion of the allowed amount that went towards the deductible)
*   `copay_amount`: $0.00 (as per plan)
*   `coinsurance_amount`: $290.00
*   `ending_member_deductible`: $2300.00 (as discussed above, based on the accumulation rule)
*   `ending_member_oopm`: $2590.00

Given that this is the only claim and therefore the "FINAL claim listed," these values should be accurate and formatted correctly. I've ensured the numbers have two decimal places as expected. Everything appears to align with the plan rules and the requested output structure.

**Adjudicating Claim 1: Processing and Accumulator Updates**

Alright, the task at hand is to meticulously adjudicate this claim based on the provided plan document and the current member accumulators. My primary goal is to determine the member's financial responsibility, the amount the plan will cover, and then update all relevant accumulators accurately.

First, I'll lay out the foundational plan details:
*   **Deductible Structure:** We're dealing with an Aggregate Family Deductible of $6,400.00. Crucially, there's no individual deductible. This means the plan won't contribute any coinsurance until the *total family* credits hit this $6,400.00 threshold.
*   **Out-of-Pocket Maximum (OOPM):** The individual in-network (INN) OOPM is $7,000.00, and the family INN OOPM is $14,000.00.
*   **Member Coinsurance (INN):** It's set at 10%.

Now, let's look at Claim 1 itself:
*   **Service:** Outpatient cardiac catheterisation, performed in-network.
*   **Billed Charge:** $9,880.00.
*   **Allowed Amount:** This is the figure that matters for benefit calculation – $5,200.00.

And the starting point for our accumulators:
*   **Member Deductible Credited:** This is where I had to pause and re-read. The plan document states, "In-network and out-of-network deductible credits accumulate to a SINGLE member deductible balance." and then clarifies, "There is no individual deductible under this structure." However, the initial accumulator *does* list "Member deductible credited" as $0.00. Given the subsequent accumulation logic, it seems the "Member deductible credited" is a tracked balance, even if no individual deductible needs to be met first. So, starting at $0.00.
*   **Family Deductible Credited:** $4,100.00.
*   **Member OOP Credited:** $0.00.
*   **Family OOP Credited:** $4,100.00.

Now, let's process Claim 1 step-by-step:

1.  **Deductible Application:** The family deductible is aggregate. We start with a total family deductible of $6,400.00 and the current family deductible credited is $4,100.00. This leaves $6,400.00 - $4,100.00 = $2,300.00 remaining on the family deductible. Since the allowed amount of the claim ($5,200.00) is more than this remaining deductible, the entire $2,300.00 will be applied to the deductible.
    *   *Deductible Applied:* $2,300.00.

2.  **Amount Subject to Coinsurance:** After applying the deductible, we have $5,200.00 (allowed amount) - $2,300.00 (deductible applied) = $2,900.00 remaining.

3.  **Coinsurance Calculation:** The member pays 10% of this remaining amount. So, 10% of $2,900.00 = $290.00.
    *   *Coinsurance Amount:* $290.00.

4.  **Total Member Cost Share (Pre-OOPM Check):** This is the sum of the deductible and coinsurance. $2,300.00 (deductible) + $290.00 (coinsurance) = $2,590.00.

5.  **OOPM Check:**
    *   Remaining Individual INN OOPM: $7,000.00 (max) - $0.00 (initial OOP) = $7,000.00.
    *   Remaining Family INN OOPM: $14,000.00 (max) - $4,100.00 (initial OOP) = $9,900.00.
    *   The member's calculated cost share of $2,590.00 is well within both the individual and family OOPM limits.

6.  **Determining Member Responsibility and Plan Paid:**
    *   Based on the above, the *Member Responsibility* is $2,590.00.
    *   The *Plan Paid* amount is the allowed amount minus the member's responsibility: $5,200.00 - $2,590.00 = $2,610.00.

Let's perform a quick sanity check:
*   Deductible applied: $2,300.00.
*   Copay applied: $0.00 (none indicated for this service).
*   Coinsurance applied: $290.00.
*   Total Member Responsibility = $2,300.00 + $290.00 = $2,590.00. This matches.
*   Total Plan Paid = $2,610.00. This also matches.

Now, for the crucial part: updating the accumulators. I need to be careful here, especially with the wording around the "member deductible."

*   **Ending Member Deductible Credited:** The initial was $0.00. We applied $2,300.00 to the deductible. As per the "SINGLE member deductible balance" rule and the request for "ending_member_deductible," this balance will now be $2,300.00.
*   **Ending Member OOP Credited:** The initial was $0.00. The member's cost share for this claim is $2,590.00. So, $0.00 + $2,590.00 = $2,590.00.
*   **Ending Family Deductible Credited:** The initial was $4,100.00. We applied another $2,300.00 to the family deductible. This brings the total to $4,100.00 + $2,300.00 = $6,400.00. This is the full family deductible.
*   **Ending Family OOP Credited:** The initial was $4,100.00. The member's cost share of $2,590.00 also counts towards the family OOPM. So, $4,100.00 + $2,590.00 = $6,690.00.

Finally, I will ensure all dollar amounts are formatted correctly as plain numbers with two decimal places, as requested.

The required output values are:
*   "member\_responsibility": 2590.00
*   "plan\_paid": 2610.00
*   "deductible\_applied": 2300.00
*   "copay\_amount": 0.00
*   "coinsurance\_amount": 290.00
*   "ending\_member\_deductible": 2300.00
*   "ending\_member\_oopm": 2590.00

**My Thought Process for Adjudicating Claim 1**

Alright, the task at hand is to adjudicate a specific claim, Claim 1, using the provided health plan document details and the member's existing accumulator balances. My ultimate goal is to generate a JSON object with the necessary fields to represent the outcome of this adjudication.

First, I need to thoroughly understand the parameters of the health plan. I've noted down the key details for the "Trinity HDHP 3200" plan for the 2026 plan year:
*   **Plan Year:** January 1, 2026, to December 31, 2026.
*   **In-network Family Deductible:** $6,400.00. This is crucial because it's an aggregate deductible structure. This means the *family* deductible must be fully met before coinsurance applies to *any* member. Importantly, there's no separate individual deductible; all deductible contributions count towards the family total.
*   **In-network Individual Out-of-Pocket Maximum (OOPM):** $7,000.00.
*   **In-network Family OOPM:** $14,000.00.
*   **In-network Coinsurance:** The member pays 10%, and the plan pays 90%, but *only after* the deductible has been met.
*   **Copays:** None.

Next, I examine the member's accumulator balances *before* Claim 1 is processed:
*   **Member Deductible Credited YTD:** $0.00. This is interesting given the "no individual deductible" clause, but the plan document does state that "deductible credits accumulate to a SINGLE member deductible balance." I need to keep this in mind for the `ending_member_deductible` field, even if it's not a distinct threshold they must meet *before* their responsibility starts.
*   **Member OOP YTD:** $0.00. This is the member's out-of-pocket spending year-to-date.
*   **Family Deductible YTD:** $4,100.00. This is the amount of the family deductible that has already been met by all family members combined.
*   **Family OOP YTD:** $4,100.00. This is the total out-of-pocket spending for the family year-to-date.

Now, I focus on the details of Claim 1 itself:
*   **Date of Service:** May 14, 2026.
*   **Service:** Outpatient cardiac catheterization.
*   **Network:** In-network.
*   **Billed Charge:** $9,880.00.
*   **Allowed Amount:** $5,200.00. This is the amount the plan considers reasonable and customary for the service, and it's the basis for all calculations.

Now, the adjudication process begins. My first step is to determine how much of the family deductible still needs to be met.
*   The family deductible is $6,400.00.
*   The family deductible YTD is $4,100.00.
*   Therefore, the **remaining family deductible** is $6,400.00 - $4,100.00 = **$2,300.00**.

Because this is an aggregate deductible structure with no individual deductible, the member must contribute towards this remaining $2,300.00 before any coinsurance applies. The allowed amount for the claim is $5,200.00.
*   The portion of the allowed amount that will be applied to the deductible is the *lesser* of the remaining deductible and the allowed amount. In this case, it's **$2,300.00** (since $2,300.00 < $5,200.00). This will be my `deductible_applied`.

After applying the deductible, I need to calculate the remaining amount of the allowed charge that will be subject to coinsurance.
*   Remaining allowed amount = Allowed Amount - Deductible Applied
*   Remaining allowed amount = $5,200.00 - $2,300.00 = **$2,900.00**.

Now, I calculate the coinsurance.
*   Member's coinsurance responsibility = 10% of $2,900.00 = **$290.00**. This will be my `coinsurance_amount`.
*   The plan's coinsurance payment = 90% of $2,900.00 = $2,610.00.

There are no copays according to the plan document, so:
*   **Copay Amount:** **$0.00**.

Now I can determine the total member responsibility for this claim.
*   Total Member Responsibility = Deductible Applied + Coinsurance Amount + Copay Amount
*   Total Member Responsibility = $2,300.00 + $290.00 + $0.00 = **$2,590.00**. This will be my `member_responsibility`.

Next, I calculate the amount the plan will pay for this claim.
*   Plan Paid = Allowed Amount - Member Responsibility
*   Plan Paid = $5,200.00 - $2,590.00 = **$2,610.00**. I can also verify this by checking the plan's coinsurance portion: $2,610.00, which matches.

A critical step is to check the Out-of-Pocket Maximum (OOPM) limits, though it's unlikely to be hit with this single claim.
*   **Member OOPM Check:**
    *   Member OOP YTD before this claim: $0.00.
    *   Member's responsibility for this claim: $2,590.00.
    *   New Member OOP YTD = $0.00 + $2,590.00 = **$2,590.00**.
    *   The individual OOPM is $7,000.00. Since $2,590.00 < $7,000.00, the individual OOPM is not exceeded. This will be my `ending_member_oopm`.

*   **Family OOPM Check:**
    *   Family OOP YTD before this claim: $4,100.00.
    *   Member's responsibility for this claim: $2,590.00.
    *   New Family OOP YTD = $4,100.00 + $2,590.00 = **$6,690.00**.
    *   The family OOPM is $14,000.00. Since $6,690.00 < $14,000.00, the family OOPM is not exceeded.

Finally, I need to determine the "ending" accumulator values, specifically for the member's deductible and OOPM.
*   **Ending Member Deductible:** The member's YTD deductible started at $0.00. $2,300.00 of the allowed amount was applied to the deductible for this claim. Therefore, the `ending_member_deductible` is **$2,300.00**.
*   **Ending Member OOPM:** As calculated above, the member's total out-of-pocket spending after this claim is $2,590.00. This will be my `ending_member_oopm`.

I've now calculated all the necessary values and cross-checked them. The required fields and their values are:
*   `member_responsibility`: 2590.00
*   `plan_paid`: 2610.00
*   `deductible_applied`: 2300.00
*   `copay_amount`: 0.00
*   `coinsurance_amount`: 290.00
*   `ending_member_deductible`: 2300.00
*   `ending_member_oopm`: 2590.00

I will format these into the requested JSON structure, ensuring all numerical values have two decimal places.

**Analyzing the Trinity HDHP 3200 Plan and a Recent Cardiac Catheterization Claim**

I'm looking at the details of the Trinity HDHP 3200 plan for the 2026 calendar year and need to process a specific claim. My goal is to determine the member's responsibility and the plan's payment based on the plan's structure and the details of the service.

First, I'll establish the key plan parameters:
*   **Plan Type:** Trinity HDHP 3200 (Synthetic)
*   **Coverage Year:** January 1, 2026, to December 31, 2026
*   **In-Network Deductible:** $6,400.00 (Aggregate Family). This is critical – it means the entire family's medical costs must reach $6,400 before coinsurance typically applies.
*   **In-Network Out-of-Pocket Maximum (OOPM):** $7,000.00 (Individual). Even though the deductible is aggregate, there's still an individual limit on what I, as a member, would pay out of pocket in total for services.
*   **Coinsurance:** 10% (member) / 90% (plan) after the deductible is met.
*   **Copays:** $0.00 (none).
*   **Preventive Care:** Covered at 100% by the plan, with no cost share.

Now, I'll assess the current status before this claim:
*   **Member YTD Deductible:** $0.00
*   **Member YTD OOPM:** $0.00
*   **Family YTD Deductible:** $4,100.00
*   **Family YTD OOPM:** $4,100.00

Next, I have a specific claim to process:
*   **Claim Date:** May 14, 2026
*   **Service:** Outpatient cardiac catheterization (In-network)
*   **Billed Amount:** $9,880.00
*   **Allowed Amount:** $5,200.00

Here's where the detailed calculation begins, using the *allowed amount* as the basis for cost-sharing:

1.  **Deductible Application:**
    *   The family deductible is $6,400.00.
    *   We've already credited $4,100.00 towards the family deductible year-to-date.
    *   This means there's $6,400.00 - $4,100.00 = $2,300.00 remaining on the family deductible.
    *   The allowed amount for this claim is $5,200.00.
    *   To satisfy the remaining family deductible, I will pay the *lesser* of the remaining deductible ($2,300.00) or the allowed amount ($5,200.00).
    *   Therefore, **$2,300.00 is applied to the family deductible from this claim.**

2.  **Coinsurance Calculation:**
    *   After applying the deductible, the remaining allowed amount is $5,200.00 - $2,300.00 = $2,900.00.
    *   This remaining $2,900.00 is subject to coinsurance.
    *   My coinsurance responsibility is 10% of this amount: $2,900.00 * 0.10 = $290.00.
    *   The plan's coinsurance responsibility is 90%: $2,900.00 * 0.90 = $2,610.00.

3.  **Total Member Responsibility and OOPM Check:**
    *   My total responsibility for this claim is the deductible portion plus the coinsurance portion: $2,300.00 + $290.00 = $2,590.00.
    *   My individual OOPM limit is $7,000.00.
    *   Since my current responsibility ($2,590.00) is well below the individual OOPM limit, the full member responsibility of $2,590.00 applies.

4.  **Updating Accumulators:**
    *   **Member Responsibility:** $2,590.00 (This is the total I owe for this claim).
    *   **Plan Paid:** $2,610.00 (This is the total the plan pays for this claim, which is the allowed amount minus my responsibility).
    *   **Deductible Applied:** $2,300.00 (This is the amount from this claim that went towards meeting the family deductible).
    *   **Copay Amount:** $0.00 (As there are no copays).
    *   **Coinsurance Amount:** $290.00 (My portion of the coinsurance).
    *   **Ending Member Deductible:** My YTD deductible was $0.00. I paid $2,300.00 towards the deductible. Therefore, my new **ending member deductible balance is $2,300.00.**
    *   **Ending Member OOPM:** My YTD OOPM was $0.00. My total responsibility for this claim is $2,590.00. Therefore, my new **ending member OOPM balance is $2,590.00.**

I've considered the aggregate nature of the deductible and the specific clause stating "There is no individual deductible under this structure," which confirms that the $6,400 family aggregate is the primary driver for coinsurance eligibility. I've also noted that cardiac catheterization is not a preventive service and thus subject to cost-sharing. The billed amount being higher than the allowed amount is standard for in-network services; my responsibility is solely based on the allowed amount. The individual OOPM limit is not a factor in this specific claim's calculation as my responsibility is significantly lower than the $7,000 threshold.

**My Thought Process on Calculating the Claim**

Alright, let's break down this cardiac catheterization claim for the Trinity HDHP 3200 plan in 2026. I'm looking at a billed amount of $9880.00, but the plan's allowed amount is $5200.00, so that's my starting point for cost calculation.

First, I need to determine if this service falls under preventive care. My understanding is that cardiac catheterization is a diagnostic and procedural service, not a standard preventive one like a physical or a basic screening. The plan explicitly states that "every covered service...is subject to the deductible and then coinsurance" unless it's specifically an in-network preventive service mandated by law. So, this claim is definitely subject to cost-sharing.

Next, I focus on the deductible. This plan uses an aggregate family deductible structure, with a total of $6400.00. Crucially, it states, "There is no individual deductible under this structure" for in-network services. However, it also mentions that "In-network and out-of-network deductible credits accumulate to a SINGLE member deductible balance." This means I need to track what the member has personally contributed towards the family deductible. The plan indicates a family deductible year-to-date (YTD) of $4100.00. My first step is to figure out how much is still needed to meet that family deductible: $6400.00 (total) - $4100.00 (YTD) = $2300.00 remaining.

Now, I apply this remaining deductible amount to the allowed charge of $5200.00. The member will be responsible for the first $2300.00 of the allowed amount to satisfy the family deductible. This $2300.00 will be credited to both the family deductible and the member's individual deductible accumulator.

After applying the deductible, I look at what's left of the allowed amount: $5200.00 - $2300.00 = $2900.00. This is the amount that will be subject to coinsurance. The plan specifies a 10% member / 90% plan coinsurance rate for in-network services after the deductible is met. So, the member's coinsurance responsibility is 10% of $2900.00, which is $290.00. The plan will cover the remaining 90%, or $2610.00.

Now, I need to check the out-of-pocket maximum (OOPM) for both the individual and the family.

For the individual member: Their responsibility for this claim is the deductible portion ($2300.00) plus the coinsurance ($290.00), totaling $2590.00. Their individual OOPM YTD was $0.00. So, their new individual OOPM balance is $0.00 + $2590.00 = $2590.00. This is well within the individual OOPM limit of $7000.00.

For the family: Their OOPM YTD was $4100.00. Adding the member's responsibility for this claim ($2590.00) brings the total family OOPM YTD to $4100.00 + $2590.00 = $6690.00. This is also well within the family OOPM limit of $14000.00.

There are no copays under this plan structure, which is consistent with the calculation.

So, to summarize the financial breakdown for this specific claim:
*   The **allowed amount** is $5200.00.
*   The **deductible applied** is $2300.00 (fully satisfying the remaining family deductible for this claim).
*   The **coinsurance amount** for the member is $290.00.
*   The total **member responsibility** for this claim is $2300.00 + $290.00 = $2590.00.
*   The **plan paid** is the allowed amount minus the member responsibility: $5200.00 - $2590.00 = $2610.00.
*   The **ending member deductible accumulator** reflects the amount applied to the deductible for this claim: $0.00 (previous) + $2300.00 = $2300.00.
*   The **ending member OOPM accumulator** reflects the total responsibility for this claim, as it contributes to the member's OOPM: $0.00 (previous) + $2590.00 = $2590.00.

I've also re-read the note about the "Individual (in-network) 3200.00" versus the "AGGREGATE" structure. The explicit statement "There is no individual deductible under this structure" for in-network services confirms that the $3200.00 listed might be a reference point but doesn't function as a separate, primary deductible for in-network services; instead, the family aggregate of $6400.00 is the threshold that must be met before coinsurance applies. Since the $2300.00 needed to meet the family deductible is less than the $3200.00 individual listed amount, even if there were some nuance to that individual figure, the application of the $2300.00 would still be the correct first step.

**My Thought Process on Processing This Outpatient Cardiac Catheterization Claim**

Alright, let's break down this claim based on the Trinity HDHP 3200 plan details. I'm looking at an outpatient cardiac catheterization, which I've confirmed is *not* a preventive service, so it will definitely be subject to cost-sharing. The service was rendered in-network, and the billed amount is $9,880.00. However, my calculations are always based on the *allowed* amount, which in this case is $5,200.00.

First, I need to consider the plan structure. This is a High Deductible Health Plan (HDHP) with an *aggregate* family deductible. That's crucial. The Family (In-network) Deductible is $6,400.00. I also note that the plan explicitly states "There is no individual deductible under this structure" for triggering coinsurance, meaning benefits beyond the deductible (like coinsurance) won't kick in until the *family* deductible is met, regardless of who has incurred the costs. However, the plan *does* have an Individual (In-network) Out-of-Pocket Maximum (OOPM) of $7,000.00, which I'll need to check at the end.

Looking at the Year-To-Date (YTD) balances:
*   Member YTD Deductible: $0.00
*   Member YTD OOPM: $0.00
*   Family YTD Deductible: $4,100.00
*   Family YTD OOPM: $4,100.00

Now, let's apply the current service to the Family Deductible.
The Family Deductible is $6,400.00, and $4,100.00 has already been met. So, I need to apply the remaining $6,400.00 - $4,100.00 = $2,300.00 from the allowed amount of this claim towards the family deductible.

After applying this $2,300.00 deductible:
*   The amount of the allowed service remaining for coinsurance calculation is $5,200.00 (Allowed) - $2,300.00 (Deductible Applied) = $2,900.00.

Next, I apply the in-network coinsurance. The plan states 10% member / 90% plan after the deductible is met.
*   My coinsurance responsibility for this portion is 10% of $2,900.00, which is $290.00.

So, my total member responsibility for this claim is the sum of the deductible applied and the coinsurance:
*   $2,300.00 (Deductible) + $290.00 (Coinsurance) = $2,590.00.

Now, I need to check this against my individual OOPM. My Member YTD OOPM is $0.00, and my responsibility for this claim is $2,590.00. Since $2,590.00 is well below the Individual OOPM of $7,000.00, I will be responsible for the full $2,590.00.

Finally, I calculate the plan's payment for this claim.
*   Plan Paid = Allowed Amount - Member Responsibility
*   Plan Paid = $5,200.00 - $2,590.00 = $2,610.00.

Let's update the YTD accumulators:
*   My Member Deductible YTD will increase by the deductible portion I applied: $0.00 + $2,300.00 = $2,300.00.
*   My Member OOPM YTD will increase by my total responsibility for this claim: $0.00 + $2,590.00 = $2,590.00.
*   The Family Deductible YTD will now be $4,100.00 + $2,300.00 = $6,400.00 (meaning the family deductible is now met).
*   The Family OOPM YTD will be $4,100.00 + $2,590.00 = $6,690.00.

Regarding the specific output keys requested:
*   `member_responsibility`: $2,590.00
*   `plan_paid`: $2,610.00
*   `deductible_applied`: $2,300.00
*   `copay_amount`: $0.00 (as the plan has no copays)
*   `coinsurance_amount`: $290.00
*   `ending_member_deductible`: $2,300.00 (this tracks my individual contribution to the deductible pool)
*   `ending_member_oopm`: $2,590.00 (this tracks my individual out-of-pocket spend)

Everything appears to align with the plan rules and the specific service details. The aggregate nature of the deductible was key here, ensuring we hit the family target first.

Let me work through this.

Plan: Trinity HDHP 3200. Aggregate family deductible 6400.00. No individual deductible under aggregate structure. In-network coinsurance 10% member / 90% plan after deductible. OOPM individual in-network 7000.00, family 14000.00.

Accumulators before Claim 1:
- Member deductible YTD: 0.00
- Member OOPM YTD: 0.00
- Family deductible YTD: 4100.00
- Family OOPM YTD: 4100.00

Claim 1: in-network, allowed 5200.00.

Aggregate deductible: family must reach 6400 before coinsurance. Family deductible is at 4100, so 2300 remaining to satisfy.

Member cost share: member pays at allowed rate toward deductible until family deductible met. So member pays 2300.00 toward deductible, then remaining 5200 - 2300 = 2900 subject to 10% coinsurance = 290.00.

Member responsibility = 2300 + 290 = 2590.00.
Plan paid = 5200 - 2590 = 2610.00.

Deductible applied = 2300.00.
Copay = 0.00 (no copays).
Coinsurance = 290.00.

Ending member deductible: member deductible credited YTD was 0.00; member just credited 2300.00 toward deductible. But wait — the aggregate structure says "There is no individual deductible under this structure." The member deductible accumulator... Hmm. The task says "ending_member_deductible — member deductible accumulator after all claims." Under aggregate structure, deductible credits accumulate at family level. But the member accumulator was given as 0.00 and family 4100.00. The deductible credit from this claim is 2300.00. Does the member deductible accumulator increase by 2300.00?

The plan says "In-network and out-of-network deductible credits accumulate to a SINGLE member deductible balance." That refers to OON. Under aggregate structure there's no individual deductible threshold, but credits still accumulate per member presumably. The member deductible accumulator would be 0 + 2300 = 2300.00.

Ending member OOPM: member OOPM credited = 0 + 2590 (all member cost share counts toward OOP) = 2590.00.

Check OOPM not reached: 2590 < 7000. Fine.

Check: member_responsibility + plan_paid = 2590 + 2610 = 5200 ✓.

Rounding: 2900 * 0.10 = 290.00 exactly.

Output JSON.

Let me work through this carefully.

- Family OOP credited YTD: 4100.00

Claim 1: 2026-05-14, outpatient cardiac catheterisation, in-network, billed 9880.00, allowed 5200.00.

Aggregate deductible: family deductible is 6400.00. Family has 4100.00 credited. Remaining family deductible: 6400.00 - 4100.00 = 2300.00.

The claim's allowed amount is 5200.00. First 2300.00 goes to deductible (member pays). Then the remaining 5200.00 - 2300.00 = 2900.00 is subject to coinsurance at 10% member: 290.00 member, 2610.00 plan.

Member responsibility: 2300.00 + 290.00 = 2590.00
Plan paid: 2610.00
Check: 2590.00 + 2610.00 = 5200.00 ✓

Copay: 0.00
Deductible applied: 2300.00
Coinsurance amount: 290.00

Ending member deductible accumulator: The member's deductible credited YTD was 0.00; this claim adds 2300.00 to the member's deductible balance. Note: "In-network and out-of-network deductible credits accumulate to a SINGLE member deductible balance." Under aggregate structure, there's no individual deductible threshold, but the member deductible accumulator still tracks the member's own credits. So ending member deductible = 2300.00.

Ending member OOPM: member OOP was 0.00; member cost share on this claim = 2590.00. So ending member OOP = 2590.00.

Check OOPM: individual in-network OOPM 7000.00 — not reached. Family OOPM 14000.00 — family OOP is now 4100.00 + 2590.00 = 6690.00, not reached.

Rounding: all exact. 2300.00, 290.00, 2590.00, 2610.00.

Okay, I've been asked to adjudicate a single claim for a member under the Trinity HDHP 3200 plan. My process is to meticulously go through the plan document and the member's accumulators before applying the claim details.

First, I need to thoroughly understand the plan document.
*   The **plan year** is January 1, 2026, to December 31, 2026. The claim date, May 14, 2026, falls squarely within this period.
*   Next, the **deductible**. For an individual in-network, it's $3,200.00, and for a family in-network, it's $6,400.00. The crucial detail here is that the deductible is **AGGREGATE**. This means the plan won't pay any coinsurance for *anyone* until the *total family credits* reach that $6,400.00 threshold. There's no way to meet an individual deductible independently.
*   The **Out-of-Pocket Maximum (OOPM)** for an individual in-network is $7,000.00, and for a family in-network, it's $14,000.00.
*   Regarding **cost share**, in-network, it's 10% member coinsurance and 90% plan coinsurance, and this only kicks in *after* the deductible is met. There are no copays on this plan.
*   **Preventive care** is usually covered at 100%, but this service, "Outpatient cardiac catheterisation," is definitely not preventive.
*   Finally, cost share calculations are based on the **allowed amount** for the service.

Now, I'll look at the **member accumulators *before* this claim**.
*   Member Deductible YTD is $0.00.
*   Member OOPM YTD is $0.00.
*   Family Deductible YTD is $4,100.00.
*   Family OOPM YTD is $4,100.00.

With all that information in hand, I can now **adjudicate this specific claim**.
*   The claim date is May 14, 2026.
*   The service is an outpatient cardiac catheterisation, rendered in-network.
*   The allowed amount for this service is $5,200.00.

Let's break down the adjudication step-by-step:
1.  **Is the service subject to cost share?** Yes, it's not preventive.
2.  **Does a copay apply?** No, the plan has no copays.
3.  **Apply the deductible:**
    *   Since it's an aggregate family deductible of $6,400.00, and $4,100.00 has already been accumulated by the family, there's $6,400.00 - $4,100.00 = $2,300.00 remaining to meet the family deductible.
    *   The allowed amount for this claim is $5,200.00.
    *   The first $2,300.00 of this allowed amount will be applied to the remaining family deductible. So, **$2,300.00 is applied to the deductible**. This amount is the member's responsibility at this stage.
4.  **Apply coinsurance:**
    *   After applying the deductible, there's a remaining portion of the allowed amount: $5,200.00 - $2,300.00 = $2,900.00.
    *   At this point, the family deductible is met ($4,100.00 + $2,300.00 = $6,400.00).
    *   Coinsurance applies to this remaining $2,900.00. The member's coinsurance responsibility is 10%.
    *   Therefore, the **coinsurance amount is $2,900.00 * 0.10 = $290.00**. This is also the member's responsibility.
5.  **Calculate Member Responsibility for this claim:**
    *   This is the sum of the deductible applied and the coinsurance amount: $2,300.00 + $290.00 = **$2,590.00**.
6.  **Calculate Plan Paid for this claim:**
    *   This is the total allowed amount minus the member's responsibility: $5,200.00 - $2,590.00 = **$2,610.00**.
    *   Alternatively, it's 90% of the amount after the deductible was met: $2,900.00 * 0.90 = $2,610.00. The math checks out.
7.  **Check against OOPM:**
    *   The member's OOPM is $7,000.00, and their YTD OOPM was $0.00. The total cost share for this claim, $2,590.00, is well within this limit, so the OOPM is not a factor in this specific calculation.

Finally, I need to **update the accumulators *after* this claim**.
*   **Member Deductible:** Even though it's an aggregate family deductible, the plan document states "In-network and out-of-network deductible credits accumulate to a SINGLE member deductible balance." So, the amount applied to the deductible from this member's claim was $2,300.00.
    *   Starting member deductible: $0.00
    *   Ending member deductible = $0.00 + $2,300.00 = **$2,300.00**.
*   **Member OOPM:** All member cost-sharing counts towards their OOPM.
    *   Starting member OOPM: $0.00
    *   Cost share for this claim: $2,590.00 ($2,300.00 deductible + $290.00 coinsurance)
    *   Ending member OOPM = $0.00 + $2,590.00 = **$2,590.00**.
*   **Family Deductible:**
    *   Starting family deductible: $4,100.00
    *   Deductible applied from this claim: $2,300.00
    *   Ending family deductible = $4,100.00 + $2,300.00 = $6,400.00. The family deductible is now fully met.
*   **Family OOPM:**
    *   Starting family OOPM: $4,100.00
    *   Cost share for this claim: $2,590.00
    *   Ending family OOPM = $4,100.00 + $2,590.00 = $6,690.00.

The request is for the JSON output with specific fields related to the *final* claim's adjudication and the *ending* accumulators for the member.

Based on my analysis, the required outputs are:
*   `member_responsibility`: $2,590.00
*   `plan_paid`: $2,610.00
*   `deductible_applied`: $2,300.00
*   `copay_amount`: $0.00
*   `coinsurance_amount`: $290.00
*   `ending_member_deductible`: $2,300.00
*   `ending_member_oopm`: $2,590.00

All these figures need to be formatted to two decimal places. The logic holds up, especially regarding the aggregate deductible and its impact on cost sharing.

Here's a breakdown of my thought process in adjudicating this claim.

First, I need to understand the core task: I'm being asked to evaluate a single claim against a provided plan document and the member's existing accumulator balances. The goal is to determine how much the member is responsible for, how much the plan pays, and to update the member's year-to-date balances.

**My Plan Document Review:**

I'll start by thoroughly dissecting the plan document provided.
*   **Plan Type:** It's an HDHP. This is important because HDHPs often have specific rules around deductibles and out-of-pocket maximums.
*   **Plan Year:** The claim date, May 14, 2026, falls squarely within the 2026 plan year (January 1 to December 31). That's good; no tricky cross-year issues.
*   **Deductible (In-Network):**
    *   Individual: $3,200.00
    *   Family: $6,400.00
    *   **Crucially, it's an AGGREGATE family deductible.** This is the linchpin of the entire calculation for this specific claim. It means that the plan won't start paying any coinsurance until the *total family credits* reach the *family deductible amount*. The individual deductible is secondary here; until the family hits its $6,400, the plan doesn't move to cost-sharing beyond the deductible.
*   **Out-of-Pocket Maximum (OOPM) (In-Network):**
    *   Individual: $7,000.00
    *   Family: $14,000.00
    *   This will be a check at the end to ensure the member's total responsibility doesn't exceed these limits.
*   **Cost Share (In-Network):**
    *   Copay: None. Simple enough, no copay to worry about.
    *   Coinsurance: 10% member / 90% plan. This applies *after* the deductible is met.
*   **Preventive Care:** The plan pays 100% for preventive services. I need to check the service type. "Outpatient cardiac catheterisation" is clearly not preventive care, so this exception won't apply.
*   **Basis of Payment:** Allowed amount. This is what we work with – the contractual rate for the service.

**Current Member Accumulators (Before this Claim):**

These are my starting point for tracking progress towards the plan's financial limits.
*   Member Deductible (Individual): $0.00
*   Member OOPM (Individual): $0.00
*   Family Deductible: $4,100.00. This is a significant amount already accumulated towards the family's $6,400 deductible.
*   Family OOPM: $4,100.00. This tells me how much of the family's overall OOPM has been met.

**Now, let's Adjudicate Claim 1:**

*   **Date:** May 14, 2026
*   **Service:** Outpatient cardiac catheterisation, in-network
*   **Allowed Amount:** $5,200.00

**My Step-by-Step Calculation Process:**

1.  **Deductible Status Check:** My first priority is the deductible. The plan has an AGGREGATE family deductible of $6,400.00. I know from the accumulators that $4,100.00 has already been met.
    *   Therefore, the remaining family deductible is $6,400.00 - $4,100.00 = $2,300.00.
    *   The plan won't pay any coinsurance until this $2,300.00 is satisfied.

2.  **Applying the Claim to the Deductible:** The allowed amount for this claim is $5,200.00. I need to see how much of this goes towards the remaining family deductible.
    *   The first $2,300.00 of the allowed amount will be applied directly to meet the remaining family deductible.
    *   So, `deductible_applied` = $2,300.00.
    *   This action successfully satisfies the family deductible for the plan year.

3.  **Applying Coinsurance:** Now that the deductible is met, coinsurance applies to the *remaining* portion of the allowed amount.
    *   Remaining allowed amount for coinsurance = $5,200.00 (total allowed) - $2,300.00 (applied to deductible) = $2,900.00.
    *   The member's coinsurance responsibility is 10%.
    *   `coinsurance_amount` = $2,900.00 * 0.10 = $290.00.

4.  **Copay Check:** As noted earlier, there are no copays under this plan.
    *   `copay_amount` = $0.00.

5.  **Calculating Total Member Responsibility:** This is the sum of what the member owes from the deductible and coinsurance.
    *   `member_responsibility` = `deductible_applied` + `coinsurance_amount` + `copay_amount`
    *   `member_responsibility` = $2,300.00 + $290.00 + $0.00 = $2,590.00.

6.  **OOPM Check (Individual):** I need to ensure this member responsibility doesn't push the individual over their OOPM.
    *   The member's individual OOPM accumulator started at $0.00.
    *   The member's responsibility for this claim is $2,590.00.
    *   The new total for the member's OOPM accumulator would be $0.00 + $2,590.00 = $2,590.00.
    *   This is well below the individual OOPM of $7,000.00, so there's no OOPM adjustment needed. The member will pay the full $2,590.00.

7.  **Calculating Plan Paid:** This is simply the total allowed amount minus what the member is responsible for.
    *   `plan_paid` = $5,200.00 (allowed amount) - $2,590.00 (member responsibility) = $2,610.00.
    *   As a quick sanity check, this also matches the plan's 90% coinsurance portion: $2,900.00 * 0.90 = $2,610.00. Perfect.

8.  **Calculating Ending Accumulators:** This is where I update the year-to-date balances.
    *   **`ending_member_deductible`**: The member contributed $2,300.00 towards the deductible on this claim. Their individual deductible accumulator started at $0.00. So, the new balance is $0.00 + $2,300.00 = $2,300.00.
    *   **`ending_member_oopm`**: The member's total responsibility for this claim ($2,590.00) counts towards their OOPM. It started at $0.00. So, the new balance is $0.00 + $2,590.00 = $2,590.00.
    *   *(For my internal understanding, I'd also note the ending Family Deductible would be $4,100 + $2,300 = $6,400, and the ending Family OOPM would be $4,100 + $2,590 = $6,690. These aren't requested outputs but help confirm the overall picture.)*

**Final Review and Confirmation:**

I'll quickly scan the required outputs against my calculations:
*   `member_responsibility`: $2,590.00. Matches.
*   `plan_paid`: $2,610.00. Matches.
*   `deductible_applied`: $2,300.00. Matches.
*   `copay_amount`: $0.00. Matches.
*   `coinsurance_amount`: $290.00. Matches.
*   `ending_member_deductible`: $2,300.00. Matches.
*   `ending_member_oopm`: $2,590.00. Matches.

The critical part was correctly interpreting the AGGREGATE family deductible and ensuring the member's responsibility was correctly allocated to both the deductible and coinsurance components, then updating the individual accumulators. The logic holds up. I am ready to generate the JSON response.

Alright, let's break down this claim. My task is to adjudicate a single claim using the provided plan document and the member's current accumulator balances.

First, I need to understand the plan details. I see this is an HDHP, and the plan year runs from January 1st to December 31st, 2026. The crucial detail for the deductible here is that it's an **aggregate family deductible**. The individual deductible is $3200, but the family deductible is $6400. This means the *entire family* must hit that $6400 threshold before the plan starts covering coinsurance for *anyone* in the family. There's no individual deductible that counts separately from the family aggregate for purposes of coinsurance kicking in. The out-of-pocket maximum (OOPM) for an individual is $7000 and for a family is $14000. After the deductible is met, the cost-sharing is 10% for the member and 90% for the plan. There are no copays mentioned, which aligns with many HDHPs. Preventive care is covered at 100%, but this claim is for an "Outpatient cardiac catheterisation," which is definitely not preventive, so it will be subject to cost-sharing. Since this is an in-network claim, I don't need to worry about out-of-network rules for now, though I note that deductible credits do accumulate to a single balance, which is standard.

Now, let's look at the member's accumulators *before* this claim. The member's individual deductible YTD is $0.00, and their individual OOPM YTD is also $0.00. However, the *family* deductible YTD is $4100.00, and the *family* OOPM YTD is $4100.00. This means the family has already put $4100 towards their $6400 aggregate family deductible.

The claim itself is for an "Outpatient cardiac catheterisation" on May 14th, 2026. It's an in-network service. The billed charge was $9880.00, but the allowed amount (what the plan considers reasonable and customary) is $5200.00. This $5200.00 is the amount I need to work with.

So, the adjudication process for this claim goes like this:

1.  **Check the Service:** As established, this is a medical service, not preventive, so it's subject to the deductible and coinsurance.

2.  **Address the Deductible:** The plan has an aggregate family deductible of $6400. The family has already met $4100 of that. That leaves $6400 - $4100 = $2300 still needed to satisfy the family deductible. The allowed amount for this claim is $5200. The first $2300 of this allowed amount will be applied to satisfy the remaining family deductible. This $2300 is entirely the member's responsibility at this stage. So, I'll record `deductible_applied` as $2300.00.

3.  **Calculate Coinsurance:** After applying the $2300 to the deductible, there's a remaining portion of the allowed amount to consider for coinsurance: $5200 (allowed amount) - $2300 (applied to deductible) = $2900. The plan's coinsurance is 10% for the member and 90% for the plan.
    *   My coinsurance portion: 10% of $2900.00 = $290.00. I'll record `coinsurance_amount` as $290.00.
    *   The plan's coinsurance portion: 90% of $2900.00 = $2610.00. This is what the plan will pay. I'll record `plan_paid` as $2610.00.

4.  **Check for Copays:** The plan document clearly states there are no copays. So, `copay_amount` is $0.00.

5.  **Determine Member Responsibility:** The total member responsibility for this claim is the sum of the deductible applied and the member's coinsurance: $2300.00 (deductible) + $290.00 (coinsurance) = $2590.00. I'll record `member_responsibility` as $2590.00.

6.  **Verify Plan Paid:** The plan's payment is the coinsurance portion I calculated: $2610.00. This matches what I've got for `plan_paid`. A quick check: $2590.00 (member) + $2610.00 (plan) = $5200.00, which is indeed the allowed amount. Everything balances.

7.  **Check Against OOPM:** The member's individual OOPM is $7000, and they've accumulated $0.00 YTD. Their responsibility for this claim is $2590.00. This will increase their individual OOPM accumulator to $0.00 + $2590.00 = $2590.00. This is well within their individual $7000 OOPM, so the maximum is not reached by this claim.

8.  **Update Accumulators:** Now, I need to update the member's balances *after* this claim.
    *   **Ending Member Deductible:** The plan has an aggregate deductible, but the member's individual deductible accumulator starts at $0.00. This member contributed $2300.00 towards the family deductible on this claim. So, the `ending_member_deductible` becomes $0.00 + $2300.00 = $2300.00.
    *   **Ending Member OOPM:** The member's individual OOPM accumulator started at $0.00. Their responsibility for this claim is $2590.00. So, the `ending_member_oopm` becomes $0.00 + $2590.00 = $2590.00.

Therefore, for this specific claim, here are the adjudicated figures:

*   `member_responsibility`: $2590.00
*   `plan_paid`: $2610.00
*   `deductible_applied`: $2300.00
*   `copay_amount`: $0.00
*   `coinsurance_amount`: $290.00
*   `ending_member_deductible`: $2300.00
*   `ending_member_oopm`: $2590.00

Let me work through this carefully.

Plan: Trinity HDHP 3200
- Individual deductible (in-network): 3200.00
- Family deductible (in-network): 6400.00
- Structure: AGGREGATE — the plan pays no coinsurance for any member until total family credits reach the family deductible amount. No individual deductible.
- Coinsurance after deductible, in-network: 10% member / 90% plan
- OOPM individual (in-network): 7000.00
- OOPM family (in-network): 14000.00

Member accumulators before Claim 1:
- Member deductible credited YTD: 0.00
- Member OOP credited YTD: 0.00
- Family deductible credited YTD: 4100.00
- Family OOP credited YTD: 4100.00

Claim 1: 2026-05-14
- Service: Outpatient cardiac catheterization, in-network
- Network: In-network
- Billed charge: 9880.00
- Allowed amount: 5200.00

Since the family deductible is aggregate at 6400.00, and family deductible credited YTD is 4100.00, the family still needs 6400.00 - 4100.00 = 2300.00 before the plan starts paying coinsurance.

Claim 1 allowed amount: 5200.00

The member needs to pay the remaining family deductible first:
- Remaining family deductible: 6400.00 - 4100.00 = 2300.00
- This 2300.00 comes from this claim's allowed amount and goes to deductible.

After deductible is satisfied:
- Remaining allowed amount: 5200.00 - 2300.00 = 2900.00
- Coinsurance: 10% member = 290.00, 90% plan = 2610.00

Member responsibility: 2300.00 (deductible) + 290.00 (coinsurance) = 2590.00
Plan paid: 2610.00

Let me check OOPM:
- Member OOP before: 0.00
- Member OOP after: 0.00 + 2590.00 = 2590.00
- Individual OOPM is 7000.00, so not yet reached.

Wait, but the member deductible accumulator is 0.00 before the claim. The family deductible is aggregate, so the member's deductible contribution is tracked separately but the family threshold is what matters.

After Claim 1:
- Member deductible credited: 0.00 + 2300.00 = 2300.00
- Family deductible credited: 4100.00 + 2300.00 = 6400.00 (family deductible now satisfied)
- Member OOP credited: 0.00 + 2590.00 = 2590.00
- Family OOP credited: 4100.00 + 2590.00 = 6690.00

Wait, but the question asks for "ending_member_deductible" and "ending_member_oopm". 

For ending_member_deductible: This is the member's deductible accumulator. The member contributed 2300.00 to deductible from this claim. But actually, in an aggregate family deductible, does the member have an individual deductible accumulator? The plan says "There is no individual deductible under this structure." 

Hmm, but the accumulators show "Member deductible credited year to date ... 0.00". So there is a member-level tracking. Let me think about what "ending_member_deductible" means.

In an aggregate family deductible, the family deductible is what matters for when coinsurance kicks in. But the member still accumulates their own deductible credits. The member deductible accumulator would be the amount this member has paid toward the family deductible.

Before Claim 1: Member deductible = 0.00
After Claim 1: Member deductible = 0.00 + 2300.00 = 2300.00

For ending_member_oopm:
Before Claim 1: Member OOP = 0.00
After Claim 1: Member OOP = 0.00 + 2590.00 = 2590.00

Now let me verify: member_responsibility + plan_paid = 2590.00 + 2610.00 = 5200.00 = allowed amount. ✓

Let me also check if the member has hit their individual OOPM. The individual OOPM is 7000.00. Member OOP is 2590.00, so not yet.

But wait — should I consider the family OOPM? The family OOPM is 14000.00 and family OOP before was 4100.00. After this claim: 4100.00 + 2590.00 = 6690.00. Not yet reached.

So:
- member_responsibility: 2590.00
- plan_paid: 2610.00
- deductible_applied: 2300.00
- copay_amount: 0.00
- coinsurance_amount: 290.00
- ending_member_deductible: 2300.00
- ending_member_oopm: 2590.00

Actually, let me reconsider the ending_member_deductible. The plan says "There is no individual deductible under this structure." So what does "ending_member_deductible" mean in this context?

The accumulator field "Member deductible credited year to date" was 0.00 before. This tracks the member's contributions toward the family deductible. After this claim, the member contributed 2300.00 toward the family deductible. So ending_member_deductible = 2300.00.

This seems right. The member's deductible accumulator tracks their personal contributions, even though the threshold is measured at the family level.

Let me double-check the OOPM. The individual OOPM is 7000.00. Does the family OOPM matter? With an aggregate family OOPM of 14000.00, typically the family OOPM works similarly — the family as a whole needs to reach 14000.00 before the plan pays 100% for everyone. But individual members could hit the individual OOPM of 7000.00 on their own.

Actually, re-reading: "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." This suggests it's per-member. The individual OOPM is 7000.00. The member's OOP is 2590.00, so they haven't hit it.

But wait, does the family OOP being at 4100.00 matter? No, for an individual member, what matters is their own OOP accumulator reaching the individual OOPM, OR the family OOP reaching the family OOPM. Since neither is reached, the plan doesn't pay 100% yet.

Actually, I need to think about this more carefully. With aggregate family OOPM, does the family OOPM of 14000.00 mean that once the family's total OOP reaches 14000.00, all members get 100% coverage? And individual members hit the individual OOPM at 7000.00?

The plan document says:
- Individual (in-network) OOPM: 7000.00
- Family (in-network) OOPM: 14000.00

And: "Once a member reaches the out-of-pocket maximum the plan pays 100%..."

So a member reaches the OOPM when either their individual OOP reaches 7000.00 OR the family OOP reaches 14000.00. Since neither is reached (member OOP = 2590.00, family OOP = 6690.00), the plan doesn't pay 100%.

Everything checks out. Let me finalize.

We have an HDHP with aggregate family deductible. Family deductible credited YTD 4100.00 before claim 1. Family deductible is 6400.00. Structure is aggregate: plan pays no coinsurance for any member until total family credits reach the family deductible amount. There is no individual deductible under this structure.

Claim 1: in-network outpatient cardiac catheterization. Allowed amount 5200.00. Not preventive (cardiac catheterization). Subject to deductible then coinsurance.

We need to compute member responsibility, plan paid, deductible applied, copay, coinsurance, ending member deductible accumulator, ending member OOPM accumulator.

Key question: what is "member deductible credited year to date" vs "family deductible credited year to date". The plan has aggregate family deductible. The member's own deductible credits? It says member deductible credited YTD 0.00, family deductible credited YTD 4100.00. Under aggregate, family amount must be satisfied in full before plan pays. Family accumulator is 4100.00. Need to reach 6400.00.

Claim allowed 5200.00. Remaining to family deductible: 6400.00 - 4100.00 = 2300.00. So first 2300.00 goes to deductible. That satisfies family deductible. After deductible, remaining allowed = 5200.00 - 2300.00 = 2900.00 subject to coinsurance 10% member / 90% plan. Member coinsurance = 290.00. Plan pays = 2610.00. Member responsibility = deductible portion 2300.00 + coinsurance 290.00 = 2590.00. No copay.

Now accumulators after claim: Family deductible credited becomes 6400.00 (satisfied). Member deductible credited? Since family is aggregate, member deductible credited... The prompt gives "Member deductible credited year to date 0.00" and "Family deductible credited year to date 4100.00". Required field "ending_member_deductible" — member deductible accumulator after all claims. Hmm. What does this mean? Under aggregate, there is no individual deductible. But they gave member deductible credited YTD 0.00. The deductible applied portion is 2300.00. Should ending_member_deductible be 0.00 + 2300.00 = 2300.00? Or should it reflect the family deductible? Let's think carefully.

The required fields include "ending_member_deductible" and "ending_member_oopm". The accumulators given include "Member deductible credited year to date" and "Member out-of-pocket credited year to date" and family versions. So likely ending_member_deductible should update the member deductible accumulator by adding deductible applied to member's deductible credited. Starting member deductible 0.00, deductible applied 2300.00, ending = 2300.00. But under aggregate family deductible, what matters is family. Still, member has contributed 2300.00 toward family deductible. The field likely wants the member's deductible accumulator after claim = 2300.00.

Ending member OOPM: Starting member OOPM credited 0.00. Member responsibility for this claim = 2590.00. Does deductible and coinsurance both count toward OOPM? Yes, deductible and coinsurance count toward OOPM. So member OOPM after = 2590.00. But wait, family OOPM credited is 4100.00. Member OOPM credited is 0.00. The member's own OOPM accumulator starts at 0.00. After claim, member OOPM = 2590.00.

Check OOPM limit: individual in-network OOPM 7000. Not reached. Family OOPM 14000, family OOPM credited 4100.00 + 2590.00 = 6690.00. Not reached.

Let's double-check: Is the member responsible for the full 2300 deductible + 290 coinsurance = 2590. Plan pays 2610. Total = 5200. Good.

Now, does the family deductible being aggregate mean the member deductible accumulator is irrelevant? The plan says "There is no individual deductible under this structure." So "ending_member_deductible" might be null? But the required keys say number. The prompt says use 0.00 for component that does not apply. But ending_member_deductible is an accumulator, not a component. We need to provide a number. Since they gave member deductible credited YTD 0.00, and the claim applies 2300.00 deductible, I think ending_member_deductible = 2300.00.

However, some might interpret that under aggregate, the family deductible is what matters, and "ending_member_deductible" should remain 0.00 because there's no individual deductible. But that seems odd given they provided member deductible accumulator and ask for ending member deductible. Let's examine the wording: "MEMBER ACCUMULATORS as of the moment before Claim 1: Member deductible credited year to date ... 0.00, Member out-of-pocket credited year to date 0.00, Family deductible credited year to date ... 4100.00, Family out-of-pocket credited year to date 4100.00". So they track both member and family accumulators. The member deductible accumulator tracks how much this member has paid toward deductible. Under aggregate, the plan pays based on family accumulator, but the member accumulator still tracks contributions. The ending member deductible should be 2300.00.

Let's ensure rounding: all values to two decimals.

- member_responsibility: 2590.00
- plan_paid: 2610.00
- deductible_applied: 2300.00
- copay_amount: 0.00
- coinsurance_amount: 290.00
- ending_member_deductible: 2300.00
- ending_member_oopm: 2590.00

Double-check coinsurance: remaining after deductible = 5200 - 2300 = 2900. 10% member = 290.00. Plan 90% = 2610.00. Good.

One nuance: The family OOPM credited 4100.00. Does the member's OOPM include other family members' spending? No, member OOPM is per member. But under family OOPM, once family reaches 14000, all members protected. But member OOPM individual 7000. Starting member OOPM 0.00.

Also, does the deductible portion count toward OOPM? Yes, typically deductible counts toward OOPM. Plan document: "OOPM: ceiling on member cost share." Deductible is member cost share. So yes.

Thereforefinal answer.

Let me work through this carefully.

Plan: Trinity HDHP 3200, aggregate family deductible of 6400.00. No individual deductible under aggregate structure.

Family deductible credited YTD before Claim 1: 4100.00
Family deductible threshold: 6400.00
Remaining family deductible: 6400.00 - 4100.00 = 2300.00

Claim 1: In-network, allowed amount 5200.00, no copays, 10% coinsurance after deductible.

Since aggregate, the family deductible must be satisfied before plan pays coinsurance. Family has 4100.00 credited, needs 6400.00. Remaining = 2300.00.

Member deductible accumulator before claim: 0.00. Under aggregate structure, there's no individual deductible; the member deductible balance is measured against... Actually, the plan says in-network and out-of-network deductible credits accumulate to a SINGLE member deductible balance. The threshold for in-network is... well, under aggregate, the plan pays no coinsurance until total family credits reach family deductible.

So for this claim:
- Apply 2300.00 of the 5200.00 allowed amount to the remaining family deductible.
- Member pays 2300.00 as deductible.
- Remaining allowed amount: 5200.00 - 2300.00 = 2900.00
- Coinsurance at 10% member: 2900.00 * 0.10 = 290.00
- Plan pays: 2900.00 * 0.90 = 2610.00

Member responsibility: 2300.00 + 290.00 = 2590.00
Plan paid: 2610.00
Deductible applied: 2300.00
Copay: 0.00
Coinsurance: 290.00

Now accumulators after Claim 1:
Member deductible credited: 2300.00 (this member's own credits)
Family deductible credited: 4100.00 + 2300.00 = 6400.00 (family deductible satisfied)
Member OOPM credited: 0.00 + 2590.00 = 2590.00
Family OOPM credited: 4100.00 + 2590.00 = 6690.00

Ending member deductible: 2300.00
Ending member OOPM: 2590.00

Wait — the member deductible accumulator. The plan says "no individual deductible under this structure." But the accumulators track "member deductible credited year to date" which starts at 0.00. Under aggregate, this member's deductible credits are 2300.00 (what they personally contributed toward the family deductible). So ending member deductible = 2300.00.

Let me verify member_responsibility + plan_paid = allowed amount: 2590.00 + 2610.00 = 5200.00 ✓
