APS Regulatory Crosswalk

Companion to the Ascerta Provenance Standard, Healthcare Coverage Profile, Version 1.0

This document maps each requirement of the Profile to the regulatory obligation whose evidence it produces. It exists to answer one question a compliance officer will ask immediately: if we do this, what does it get us?

This is a mapping aid, not legal advice

Regulatory instruments are amended, and their application depends on line of business, state, and plan type. Effective dates and applicability should be confirmed with counsel against the current text of each instrument. Nothing here establishes that conformance to the Profile satisfies any legal obligation; it establishes what evidence conformance produces, which is a different and narrower claim.

Section 4 of this document lists obligations the Profile deliberately does not satisfy.

How to read this

Regulation in this area does three distinct things, and they are easy to conflate:

  • Constrains how a decision may be made — a licensed clinician must decide; the basis must be the individual's circumstances.
  • Constrains how fast, and what must be told to whom — decision timeframes, specific denial reasons, appeal rights.
  • Requires that all of the above be demonstrable on examination — records, documentation, governance.

APS produces evidence for the third category, about the first. It does not make a decision lawful; it makes a lawful decision provable, and an unlawful one detectable. The second category — timeliness, notice delivery, API transport — is largely outside the Profile, and Section 4 says so.

2.1

A qualified human must be accountable for an adverse determination

Obligation → APS requirement
Where it comes fromWhat it requires
CMS-4201-F (Medicare Advantage utilization management)Medical-necessity determinations must rest on the individual's circumstances; an algorithm may not be the sole basis; coverage criteria must be reviewed by a qualified committee
CA SB 1120 (Physicians Make Decisions Act)A licensed physician must make the medical-necessity determination; AI may not be the sole basis for a denial
TX SB 815Restricts AI as the sole basis for an adverse utilization-review determination
NAIC Model Bulletin on the Use of AI Systems by InsurersGovernance, documentation, and testing of AI systems, with records available to the regulator on examination
APS evidence
  • §5 — the accountable licensed reviewer is identified for every adverse determination, along with what they actually did: decided independently, confirmed the recommendation, or overrode it. An adverse determination with no accountable reviewer is non-conformant, which converts the obligation from a policy statement into a record that either exists or does not.
  • §5 — reviewer credential and specialty recorded beside the clinical issue, so a competence mismatch is visible on inspection rather than requiring a separate investigation.
  • §3.4 — the decider field states whether a model or deterministic code issued the determination. This is the direct, single-field answer to "did AI deny this claim?"
  • §6 — the full routing chain for every non-approval, so the path from the AI's output to the final human determination is reconstructable end to end.
2.2

The determination must rest on the individual's clinical circumstances

Where it comes fromWhat it requires
CMS-4201-FDeterminations based on the enrollee's medical condition and individual circumstances, not group or population data
CA SB 1120AI must base its output on the individual's clinical history and circumstances, not solely on a dataset of other patients
Colorado SB 21-169Insurers must be able to demonstrate that external consumer data and algorithms do not produce unfair discrimination
ACA §1557 patient care decision support provisionsReasonable efforts to identify and mitigate discrimination risk arising from decision support tools
APS evidence
  • §8 — the record must show which of the member's own clinical facts were before the system.
  • §3.1 — the evidence manifest, with a per-document presented_to_model flag. This is what makes §8 real: a fact on file that was never presented to the system was not before it, and no other part of the record distinguishes those two states.
  • §3.2 — the complete input surface, so any non-clinical content that entered the decision — a cost signal, a utilization target, a population statistic — is present in the record rather than inferred from the outcome.
  • §4.2 — extraction output with each fact pointed at its location in the source packet; facts not traceable to the packet are marked ungrounded.
2.3

An adverse determination must state a specific reason, and the record behind it must be producible

Where it comes fromWhat it requires
CMS-0057-F (Interoperability and Prior Authorization)Impacted payers must provide a specific reason for denial, and publicly report prior-authorization metrics
ERISA claims procedure regulation, 29 CFR 2560.503-1The specific reason for an adverse benefit determination, reference to the plan provision relied on, and — on request — access to all documents relevant to the claim
State external-review and appeals statutesThe record considered must be producible to the reviewing body
APS evidence
  • §3.4 — the stated basis with principal reasons for any adverse outcome, and any generated reasoning retained in full and untruncated.
  • §3.2 — the coverage rule's full text, hash-pinned to the version in force. A version identifier alone does not establish what the criterion said on the day; policies are revised, and an appeal turns on the wording that applied.
  • §9.3 — every artifact retrievable under a declared custody arrangement. This is the direct answer to the ERISA "relevant documents" obligation: the record is not merely provable, it is producible.
  • §3.1 — the manifest settles the recurring appeals dispute about whether a document was before the reviewer, arrived afterward, or was later amended.
2.4

AI systems must be governed, documented, and demonstrable on examination

Where it comes fromWhat it requires
NAIC Model Bulletin (adopted by a growing number of states)A written AI governance program; testing for validity and drift; oversight of third-party AI vendors; documentation available to the regulator
CMS-4201-FUtilization-management committee oversight of the criteria applied
State AI utilization-review statutesDisclosure of AI use in utilization review, and in several states, regulator access to the methodology
APS evidence
  • §7 — the assurance state carried on every decision: certificate and version, per-capability-line verdicts, applicable conditions and whether they were met, monitoring status, and the configuration fingerprint observed versus the one certified.
  • §7 — lapsed monitoring forces affected capability lines to be recorded as lapsed rather than certified, which is the evidentiary form of "governance must be ongoing."
  • §3.3 — the execution configuration, with every change to a routing threshold written as a dated, attributable ledger entry. This is the auditable form of vendor and configuration oversight.
  • §11.1 — coverage measured against determination volume from the source system, so the governance claim is quantified rather than asserted.
  • §4 — for a deployment using a third-party vendor, the pipeline chain records what that vendor's system did to the inputs, which is the substance of third-party oversight.
2.5

Records must be retained, protected, and their handling auditable

Where it comes fromWhat it requires
HIPAA Security Rule, 45 CFR §164.312(b)Audit controls: mechanisms recording and examining activity in systems containing ePHI
HIPAA Security Rule, 45 CFR §164.308Administrative safeguards, including information-system activity review
CMS record-retention requirements (Medicare Advantage and Medicaid managed care)Retention of records for the applicable period
HIPAA Privacy Rule, 45 CFR §164.502(b)Minimum necessary: disclose only what the purpose requires
HIPAA Privacy Rule, 45 CFR §164.528Accounting of disclosures: on request, tell an individual who received their information and why, going back six years
HIPAA Privacy Rule, 45 CFR §164.512Permitted disclosures without authorization — health oversight agencies, judicial and administrative proceedings, and disclosures required by law
APS evidence
  • §9.1 — signed, append-only, hash-chained ledger; corrections by appended linked record, never overwrite.
  • §9.5 — every disclosure recorded as a ledger event: what, to whom, when, under what authority, scoped and expiring. This is the audit-control obligation made verifiable rather than merely logged.
  • §9.6 — integrity verification operates on digests, so auditing AI involvement and human accountability does not require exposing protected health information.
  • §9.4 — retention for the required period, with an express preference against retaining readable clinical content beyond it.
  • §9.3 — the custody arrangement is declared, which is what makes a minimum-necessary posture auditable rather than asserted.
The disclosure log is an accounting-of-disclosures engine

§164.528 gives an individual the right to ask who received their information and why, going back six years. Most plans satisfy this by hand, slowly, from incomplete sources.

§9.5 records every disclosure — what, to whom, when, under what authority — as a signed ledger event. That is the accounting, produced as a by-product of making disclosures properly.

The same record answers a second question no manual process can: because the disclosure is timestamped in the same chain as the determination, the plan can show a record existed in that exact form before anyone requested it.

2.6

Disclosing to regulators, courts, and members

Where it comes fromWhat it requires
HIPAA §164.512(d)Disclosure to health oversight agencies — state insurance departments, CMS, OIG — is permitted without authorization
HIPAA §164.512(e)Disclosure in judicial and administrative proceedings, subject to specified assurances
HIPAA §164.502(b)Minimum necessary: only what the purpose requires
HIPAA §164.524The individual's right of access to their own record
State external-review statutesProduction of the record considered, to the independent review entity

These disclosures already happen daily. The question a regulator asks is not whether a plan may disclose but whether it can show what it disclosed, to whom, and that it disclosed no more than the purpose required.

APS evidence
  • §9.5 — disclosure is scoped to the determinations at issue and expires, which is the minimum necessary rule expressed as a control rather than a policy.
  • §9.5 — a standing export of the whole population is expressly not a disclosure. That distinction is the difference between a governed release and an unbounded copy.
  • §9.1 — because the disclosure event is appended to the same chain, the record of what was released cannot later be revised.
2.7

Public reporting on how coverage decisions are made

Where it comes fromWhat it requires
CMS-0057-FImpacted payers must publicly report prior-authorization metrics on their website, annually
CMS-4201-FMedicare Advantage internal coverage criteria must be publicly accessible
State AI utilization-review statutesDisclosure that AI is used in utilization review

The direction of travel is settled: plans are being required to say more, publicly, about how coverage decisions are made. What no instrument yet provides is a way for a plan to show that what it says is true.

APS evidence
  • §11.3 — a public attestation with a defined content set: profile and version, reporting period, coverage rate, chain verification status with its as-of time, certification per capability line, and custody arrangement.
  • §11.3 — the attestation must be independently verifiable against the ledger without access to clinical content, so the claim is checkable rather than asserted.
  • §11.3 — it must carry no protected health information, no per-determination data, and no approval or denial statistics. It attests to provenance posture, never to the merits of determinations, which is what makes it publishable at all.
  • §11.1 — the coverage rate is measured against determination volume from the source system, so a published figure cannot be inflated by counting only the records that were produced.
2.8

Configuration changes that shift outcomes must be detectable

No instrument names this obligation directly. It is included because it is where the others fail in practice, and because it is the first thing a plaintiff's expert or a market-conduct examiner will look for once they understand the architecture.

Where an approval threshold governs which cases reach a human, lowering it routes more cases to human review, where more can be denied — and the denial rate moves without any individual determination appearing to change.

APS evidence
  • §5 — the routing logic must be recorded and held tamper-evident.
  • §3.3 — threshold changes are written as dated, attributable ledger entries, so a retroactive or silent change is detectable.
  • §9.1 — append-only commitment means the historical threshold cannot be revised to match a later account of it.

What the Profile does not satisfy

Conformance does not make a determination correct or lawful

The Profile records what happened. A fully conformant record of an unlawful denial is a complete, tamper-evident record of an unlawful denial. That is useful — it is how the denial becomes contestable — but it is not compliance with the underlying standard of care.

Decision timeframes

CMS-0057-F expedited and standard turnaround requirements are operational obligations. The Profile timestamps determinations, which makes timeliness measurable, but meeting the deadline is not a provenance property.

Transport and API conformance

The FHIR Prior Authorization API, Patient Access, Provider Access, and Payer-to-Payer APIs are interface obligations. The Profile holds that the mode of transmission does not reduce what must be recorded (§6), but it does not implement or satisfy those interfaces.

Notice and appeal-rights delivery

Whether the member received a compliant adverse determination notice, with correct appeal-rights language, is outside the record.

Nondiscrimination outcomes

The Profile makes the inputs to each determination inspectable, which is a precondition for disparate-impact analysis. It does not itself perform that analysis, and conformance is not evidence that a deployment produces equitable outcomes.

Licensure and credentialing

The Profile records the reviewer's credential and specialty beside the clinical issue so a mismatch is visible. It does not verify the credential, and does not adjudicate whether it was adequate for the case — that judgment belongs to the plan and its regulator.

State-by-state applicability

Which instruments bind a given deployment depends on line of business, state of issue, and plan type. This document maps obligations to evidence; it does not determine which obligations apply.
