Article Detail - Portal Guide

The Noridian Medicare Portal (NMP) now provides Remittance Advice Remark Codes (RARC) and Reason Narratives to provide additional information on Medicare Part B unprocessable claim denials. The Remark Codes will be displayed on the Claim Status Line Details when a Claim Status Inquiry is performed. Users can then use the RARC codes to determine the reason for the denial and make the necessary adjustments to the claim.

Note: Medicare uses the Remark Codes published by X12.
