N382 denial code
A remark code: the patient identifier is missing, incomplete, or invalid. The member ID on the claim failed the payer's check — wrong format, wrong digits, or nobody's number. It usually rides with CO-16 or PR-31 and tells you which field to fix.
RARC — Remark Code. A remark code adds detail to an adjustment. On a CO-16 it is the remark code that actually tells you what was missing.
Why you got it
- 1A mistyped member ID — a digit off, a dropped suffix, a leading letter missing.
- 2An old ID from before the payer reissued cards or migrated systems.
- 3The right ID for the wrong payer — the claim went somewhere this number means nothing.
How do I fix a N382 denial?
- Pull the card, re-run eligibility, and correct the identifier exactly as the payer's system has it — including any alpha prefix or member suffix the desk trimmed off.
- Resubmit as a corrected claim. This is a data fix; there is nothing to argue.
How to stop the next one
Card scans beat transcription. Every hand-keyed member ID is a chance to mint this remark, and the eligibility check that would catch it costs seconds at check-in.
Our diagnosis scrubber will not catch this one. N382 is driven by procedure codes, modifiers, or eligibility rather than by the diagnosis set — and procedure-side checking needs CPT codes, which aren’t included yet. We would rather tell you that than sell you a tool that quietly misses your most common denial.
If denials like this are a volume problem rather than a one-off, the denial management page explains how the paid workspace catches the coding causes on every claim, and the free ICD-10-CM lookup shows the coding notes behind any diagnosis code on the remittance.

- CO-16The claim is missing information the payer needs, or something on it is inconsistent.
- PR-31The payer cannot match the patient to a member.
- MA130Your claim is unprocessable: something on it is incomplete or invalid, and — this is the part that matters — it comes with no appeal rights, because in the payer's eyes no claim was ever properly filed.
