Requests for Additional Codes

60.4 - Requests for Additional Codes (Rev. 3288, Issued: 07-02-15, Effective: 08-03-15, Implementation: 08-03-15) The CMS has a national responsibility for maintenance of the remittance advice remark codes and the Claim Adjustment Status Code Maintenance Committee maintains the claim adjustment reason codes. Requests for new or modification or deactivation of RARCs and CARCs should be sent to a mail box set up by CMS: Remittance_Advice.CMS.HHS.GOV. The MACs should send their requests to this mail box for any change in CARC, RARC or any code combination. Requests for codes must include the suggested wording for the new or revised message, and an explanation of how the message will be used and why it is needed or a justification for the request. To provide a summary of changes introduced in the previous 4 months, a code update instruction in the form of a CR is issued. These CRs will establish the deadline for Medicare shared system and MAC changes to complete the reason and/or remark code updates that had not already been implemented as part of a previous Medicare policy change instruction.
