Denial Code 251

CARC 251: The attachment/other documentation that was received was incomplete or deficient. The necessary information is still needed to process the claim. Remark code required

This is a Claim Adjustment Reason Code (CARC). CARCs explain why a payer adjusted or denied a claim line and appear with a group code (CO, PR, OA, PI). Codes appear on the EOB / ERA after a claim is adjudicated.

Reference only — CARC/RARC are national code sets updated periodically. Verify against the current official list before acting on a denial or appeal.
