Denial Code MA43

RARC MA43: Missing/invalid patient status

This is a Remittance Advice Remark Code (RARC, MA-series) — a remark that supplements a CARC on the remittance advice (ERA/EOB) to add detail. 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.
