Official CARC description: “Patient cannot be identified as our insured.” Here’s what it actually means, why it fires, and how to get the claim paid.
PR-grouped twin of CO 31 — the payer additionally implies the patient can be billed. Don't statement anyone until identity work is done; it's nearly always fixable data.
Liability group: PR = Patient Responsibility — the amount can be billed to the patient (deductible, coinsurance, non-covered care) — but only after you verify the denial is correct. Mis-grouped PR denials are a common appeal win.

Coverage discovery tools before writing off or statementing
Correct and resubmit; keep original submission proof
No merits appeal — identity correction plus resubmission. Newborn retro-enrollment claims deserve a reprocessing request with the enrollment confirmation.
Fill in the denial facts — use placeholders, never real patient data (the letter keeps [PATIENT NAME]-style fields so you can merge real details privately). A payer-ready draft with an enclosure checklist comes back in ~20 seconds.
