For Revenue Cycle & Denials Management
Payers review claims with AI. Strix governs the AI you field to respond.
As payers use AI to adjudicate, providers get more medical-record requests (ADRs) and AI-assisted denials than a revenue-cycle team can work by hand — so requests go unfilled and denials pile up. The only way to keep pace is to field AI on the response side: agents that assemble records, submit corrected claims, and file appeals. But an agent acting unsupervised on PHI and payer transactions is its own exposure. Strix evaluates each action at the instant it runs, blocks the ones that veer, and binds every response to an Ed25519-signed, timestamped record the payer can verify — turning 'we responded on time' from an assertion into proof.
Answers the question: “How can providers respond to AI-driven payer denials at scale without an unsupervised agent over-disclosing PHI or missing the proof?”
What the payer's automation does to your back office
AI lets payers generate ADRs and denials at machine speed while your team still responds at human speed. These are the failure modes that show up the moment a provider fields its own agent to close that gap — each one a real transaction, a PHI disclosure, or an unwinnable denial dispute.
Unfilled requests, then non-response denials — an ADR goes unworked past the deadline, or the agent responds but you cannot prove to the payer what you sent or when. The claim denies for 'records not received,' pure revenue leakage with no clinical dispute.
Over-disclosure — to 'be safe,' the agent attaches more of the chart than the ADR asked for. That is a minimum-necessary violation, and it hands the payer material to question claims it never asked about.
Wrong record — a retrieval error or an injected worklist note binds the response to the wrong patient or date of service. A wrong-patient packet is a reportable breach and denies the claim anyway.
Duplicate appeals — a retry or orchestration replay files the same appeal, or resubmits the same corrected claim, twice. The duplicate trips payer dedup and can stall the appeal clock.
Auto-fired attestations — the agent submits a high-dollar appeal asserting a clinical attestation of medical necessity that no clinician reviewed. Logs record it after the fact; by then it is already at the payer.
Does this happen on your stack?
Five questions about what your denial-and-ADR-response agent does the moment it acts on its own. The gaps you flag are exactly what the demo below shows being stopped — or admitted with proof.
When a payer denies a claim for 'records not received' months after your agent responded to the ADR, can you prove — to the payer — exactly what you sent and when?
If the agent 'plays it safe' and attaches more of the chart than the ADR asked for, does anything stop the over-disclosure before it reaches the payer?
If a retrieval error or an injected worklist note binds the response to the wrong patient or date of service, can it still be transmitted?
If the agent's run is retried, can it file the same appeal — or resubmit the same corrected claim — to the payer twice?
When the agent submits a high-dollar appeal that asserts a clinical attestation of medical necessity, is it held for a clinician — or does it just fire?
See it run — same agent, governed vs. ungoverned
The same AI response agent, run twice on an identical task. Pick a scenario: the left column is the agent with policy and guardrails only, the right is the same agent with Strix evaluating each action at the moment it executes. Synthetic patients and a mock payer only.
Respond to the payer's medical-record request (ADR) for claim CLM-44021 — send the operative note and pathology report before the 30-day deadline.
- Both runs assemble the requested records and transmit them as an X12 275 before the deadline.
- Months later the payer asserts the records were never received, and denies the claim for non-response.

Same agent · same task · same payer. The only difference is whether each action is re-evaluated at the moment it executes. Evidence IDs and signatures shown are illustrative, hand-authored captures of the record shape; production records are Ed25519-signed and verify against the public JWKS with @strixgov/verifier.
What Strix does on every response action
Strix wraps the actions a denial-and-ADR-response agent can take — assemble a packet, transmit a 275, submit an 837 correction, file an appeal. Each one is evaluated at the moment of execution against the intent that was actually approved, and bound to a signed record. The demo above runs the identical agent twice so the difference is visible side by side.
| Capability | How Strix delivers it |
|---|---|
| PROVE — timely response | Every admitted response is bound to an Ed25519-signed record carrying the documents sent, the claim, and the submission timestamp. When the payer later claims non-response, the signed receipt is the answer — verifiable against the public JWKS, not your internal log. |
| BLOCK — over-disclosure | The records about to be transmitted are compared to what the ADR requested. Anything beyond the request is blocked as OUT_OF_SCOPE before any PHI leaves — minimum-necessary enforced at execution, not audited afterward. |
| BLOCK — wrong record | The packet's patient and date-of-service binding is checked against the ADR being answered. A wrong-patient or wrong-DOS response is blocked as SCOPE_MISMATCH before it reaches the payer — closing the breach path. |
| BLOCK — duplicate appeal | Appeal and corrected-claim authority is single-use. A retried or replayed submission is blocked as REPLAY — exactly one appeal or correction goes out, even under an orchestration retry storm. |
| INTERCEPT — clinical attestation | High-dollar appeals and clinical attestations do not auto-execute. They are routed for a coder or physician to approve first, issued as a single-use, time-bound token. The action runs once, then the authority is spent. |
| VERIFY — by the payer, not by us | Every governed action — admitted or blocked — produces a signed record an auditor or the payer checks themselves against the public JWKS with a standard verifier. The verdict comes from the cryptography, not from a Strix dashboard. |
Proof, not promises
Every claim Strix makes is backed by an artifact you can independently verify.

Same agent, governed vs. ungoverned
The side-by-side demo above replays the same response agent across the five failure modes — once with policy and guardrails only, once governed by Strix. Synthetic patients and a mock payer only; it never touches a live payer, clearinghouse, or EHR.
Proof of timely response
The strongest artifact for a denials team: an Ed25519-signed, timestamped record of exactly which documents answered which ADR, before the deadline. It is the record that wins the downstream non-response dispute — and the payer verifies it without trusting you.
JWKS endpoint
The public half of the signing key, served at the canonical RFC 7517 path. A payer or auditor resolves any record's key ID here and checks the signature without contacting Strix.

The same command a payer's or your compliance reviewer would run. Open-source, npm-installable, standard Ed25519 + JWKS primitives — zero Strix dependencies in the verification path.
npx @strixgov/verifier@latest <evidenceId>Frequently asked questions
Does Strix make my agent respond faster or beat the deadline for me?+
No — and we are careful not to claim that. Strix does not move records or speed up your retrieval; it governs the action your agent takes and signs a record of it. What it changes about the deadline is the proof: when an admitted response is bound to a signed, timestamped receipt, a later 'records not received' denial becomes answerable instead of being your word against the payer's. Throughput is still your integration's job; defensibility is what Strix adds.
Does the demo touch a real payer, clearinghouse, or any PHI?+
No. The demo runs against synthetic patients and an in-process mock payer that we own. There is no production target in the code, and it never connects to a live payer, clearinghouse, or EHR. The X12 275 / 837 transactions are real in structure but carry no protected health information.
Is this a different product from the prior-auth governance?+
No. It is the same execution-control layer applied to the back end of the revenue cycle instead of the front. The prior-auth pages govern the agent that submits a 278; this one governs the agent that responds to ADRs, files corrected claims, and appeals denials. The primitives — capability registry, three-state decisions (allow / deny / intercept), single-use tokens, and signed evidence — are identical.
Where does the patient and claim data live?+
In your environment. Strix governs the action — the capability, the actor, the intent, and the context — and produces a signed evidence record of the decision. The records the agent assembles stay in your systems. Tenant data is isolated at the database with row-level security; cross-tenant reads return nothing.
How would the payer or my compliance team verify a record?+
They run the external verifier against the evidence ID and get a cryptographic verdict — verified or not — without going through a Strix UI. The verifier fetches the public key from the JWKS endpoint and checks the Ed25519 signature over the canonical payload. The point of the design is that they check it themselves; they do not take our word for it.
Can we pilot this on one of our own response workflows?+
Yes — that is the design-partner offer. We scope a pilot on a single ADR-response, corrected-claim, or appeals workflow you already run, set it up white-glove, and time-box it to a few weeks to answer one question: did it prevent a real mistake — or produce the proof that won a real denial — in your environment. Use Book a Demo to start.
