{"slug":"claims-handling-determination-record","title":"The unfair-claims acts require a reasonable investigation and a reasonable explanation. When AI touches the determination, here is the claim file that proves both.","body":"## The obligation the claim file has to prove\n\nEvery US state regulates how insurers handle claims, nearly all through some adopted form of the NAIC's model unfair-claims-settlement-practices act. The prohibited practices read like a checklist of what a claim file must be able to disprove: **refusing to pay claims without conducting a reasonable investigation based upon all available information**; failing to affirm or deny coverage within a reasonable time; failing to provide a **reasonable explanation of the basis** in the policy, in relation to the facts, for a denial or compromise offer. Enforcement varies by state — some departments of insurance only, some a private right of action — but the two core duties are constant: investigate reasonably, and explain the denial from the policy and the facts.\n\nBad-faith litigation is where those duties get priced. When a denied claim goes to suit, the fight is almost never about what the policy says in the abstract. It is about the claim file: **what the adjuster knew, what the adjuster considered, and what the adjuster ignored**. Plaintiff's counsel deposes the adjuster on every entry and builds the case in the gaps — the medical record in the file but never mentioned in the denial letter, the coverage question resolved without a written why. The file is the evidence; an adjuster's unsupported memory of having considered something is worth what any interested party's memory is worth in litigation.\n\nNow put AI into that picture. Claims automation is the most heavily-scrutinised application of AI in insurance: state regulators have been adopting the NAIC's model bulletin on insurers' use of AI systems, several states have issued bulletins and regulations aimed specifically at algorithmic claim handling, and the highest-profile insurance litigation of recent years has been class actions alleging algorithmic wholesale denial without the individualized review the claims acts require. The regulatory posture is consistent: an insurer answers for its AI's claim decisions to the same standard as its human adjusters', and the burden of demonstrating a reasonable investigation does not shrink because software did the investigating.\n\nWhich produces the question this page answers: **when an AI touches a claim determination, what does the claim file look like, such that it survives the deposition?**\n\n## The determination record, mechanically\n\nThe **policy provisions** in play — the coverage grant, the relevant exclusions, the conditions — are pinned to a content hash. The version of the policy language the determination was made under is beyond dispute: not \"the 2024 form, we believe,\" but a hash any party can recompute. The **claim file** is the record, hashed the same way: the loss notice, the photographs, the estimates, the statements, each an identified evidence record.\n\nThree model seats, drawn from two model families, each receive the identical provisions and file, under a governing constitution that compels one output shape: the verdict; the provisions relied on; a provision-by-provision derivation — did each provision's condition trigger on this file, does that support or defeat payment, on which evidence records; the records that were **absent**; the strongest rejected alternative reading; and what evidence would flip the conclusion.\n\nA deterministic parser — ordinary software, not another model — projects each finding into canonical form. A finding that cites an exclusion the policy does not contain, omits a required field, or lacks its terminal decision line is **voided**: structurally invalid output can never support a determination:\n\n[[embed:source:s1]]\n\nThe surviving findings go to the derivation-agreement gate. The gate does not compare verdicts. It compares the canonical derivations. Only when independent seats agree provision by provision, trigger state by trigger state, evidence record by evidence record does the determination seal. The closest published analogue to a coverage provision applied to a claim file — a contractual service-credit clause applied to an evidence record by this exact panel, end to end — is here:\n\n[[embed:source:s8]]\n\nAnd the panel has a third outcome besides pay and deny. When the provisions, honestly applied, license **no action** on the record before it — the file does not yet establish the loss, or a condition precedent is unmet — that abstention seals as its own receipt rather than defaulting into a denial:\n\n[[embed:source:s4]]\n\nA system that can only approve or deny manufactures wrongful denials at the margin, forcing every under-documented claim into one of two boxes. The sealed NO_ACTION is the record of the system declining to do that.\n\n## The absence declaration: the fact bad-faith discovery fights over\n\nOne compelled field deserves its own section, because it is the field the entire bad-faith discovery apparatus exists to reconstruct: **what the claim file lacked at determination time**.\n\nIn litigation, \"what did the adjuster not have, and did they know they didn't have it\" is established through depositions, file-stamp forensics, and inference — years later, against an adjuster with every incentive to remember generously. The claims acts make the question load-bearing: an investigation is not reasonable if it ignored available information, and a denial is not reasonably explained if it silently assumed facts the file never contained.\n\nIn this record format, the absence declaration is not reconstructed. It is **compelled at determination time**. Every seat must enumerate the records it did not receive that bear on the determination — the missing inspection report, the medical record referenced but not attached — before its finding is even eligible for the gate. The declaration sits inside the sealed receipt, hashed with everything else, dated to the moment of determination.\n\nThat field cuts both ways in a later dispute. The insurer can show, per determination, that the gaps in the file were identified, named, and either resolved or escalated — the documented reasonable investigation the statute demands. And a determination that proceeded despite a declared material absence is visibly defective on its own record, no deposition required. The record is not pro-carrier or pro-claimant. It is pro-file.\n\n## Unanimous is not enough\n\nThe strongest exhibit is the case every claims-compliance officer should sit with. Three seats returned the **same verdict**, citing the **same clauses** — and the gate still refused to conclude, because two had derived that verdict through different trigger states:\n\n[[embed:source:s2]]\n\nTranspose that into a claims file. Three reviewers concur; in any memo-based process, the file closes. Here the concurrence was inspected at the level of reasoning and found hollow — same answer, different theories of the policy — and the output was a **refusal, escalated to the named human adjuster**, with the divergent derivations preserved verbatim. Agreement that hides disagreement is precisely the false consensus bad-faith counsel takes apart on cross-examination. This gate takes it apart first, mechanically, and files the evidence.\n\nEscalation is not a failure state; it is the designed handoff. The machine record establishes what was determinable on the file, and everything else arrives at the adjuster's desk with the disagreement already articulated — which provisions, which trigger states, which records the seats read differently. When the panel does agree derivation-for-derivation, the other artifact results — the sealed authorisation, every seat firing the same provisions in the same states on the same records:\n\n[[embed:source:s3]]\n\n## Measured, not asserted\n\nA claims process owes the regulator numbers, not adjectives. The panel's calibration study ran 30 oracle-labelled cases — synthetic fixtures with determinate, known-correct outcomes — through the production gate. The strongest seat (glm-5.2) scored 30 of 30; the second (kimi) 29 of 30. The figure that matters most to a claims file: across all 30 sealed outcomes, **zero wrongful authorisations** — the divergence machinery caught the one seat error before it could authorise anything:\n\n[[embed:source:s6]]\n\nThose numbers come from synthetic determinate fixtures, and the limits of that are stated below. But note what kind of number they are: a **wrongful-determination rate under known ground truth**, per seat and for the gated system, re-runnable against the same hashed suite whenever a vendor swaps a checkpoint underneath you. That is evidence a market-conduct exam can use, and a different object from \"our accuracy is high.\"\n\n## When the policy is the problem\n\nA recurring finding in claims disputes is that the model — or the adjuster — was never the failure. The policy language was. The same machinery audits its own inputs: a governed seat, asked to critique a case file as a colleague, returned eight defects, the lead one an ambiguity in the rule set itself, which had silently caused every prior derivation divergence on that case:\n\n[[embed:source:s5]]\n\nFor a claims organisation this is the difference between filing a finding against the model and filing it against the form. Divergence that traces to ambiguous policy language is a drafting problem, and the record says so with a receipt — before the ambiguity gets construed against the drafter in court.\n\n## Two sides of the same record\n\nThis page is the claims-side of a pair. The carrier-side treatment — AI-performance risk as an underwritable exposure, with the measured per-seat rate table as the actuarial input — is the sibling article:\n\n[[embed:source:s7]]\n\nThe receipts are the same objects in both. A claims-automation vendor holding determination records of this shape has simultaneously built its compliance file and the evidence base an underwriter prices its E&O and AI-performance cover from — because both audiences ask the same question: at what rate is this system wrong, and what happens when it is?\n\n## What this is not\n\nStated as plainly as the rest, because a determination record that oversells itself is defective by its own standard:\n\n- **Not a claims system.** Nothing here adjusts claims, pays claims, or interfaces with any policy-administration or claims platform. It is a determination-record format, demonstrated on the live panel, with receipts.\n- **No state-DOI conformance analysis.** No mapping of this record to any specific state's unfair-claims-practices statute, bulletin, or regulation has been performed. The claims acts vary by state; treating this page as a compliance opinion for any jurisdiction would be an error.\n- **Coverage judgement on ambiguous language stays human.** Where policy language is genuinely ambiguous, the panel's designed output is divergence and escalation — the construction of ambiguous terms is the human adjuster's and ultimately a court's, and the format's contribution is to arrive at that desk with the ambiguity documented rather than buried.\n- **Synthetic fixtures only.** Every published number comes from synthetic, determinate test cases. No live claim, no real policyholder data, and no real policy form has been through this panel. The calibration table is a starting instrument, not an actuarial basis.\n\n## Submit a case\n\nSend one bounded determination question — a policy excerpt and the claim-file records bearing on it, synthetic is fine — to **build@miscsubjects.com**.
