Remittance Advice Remark Code

Acronym: RARC

Remittance Advice Remark Codes (RARCs) are used to provide additional explanation for an adjustment already described by a Claim Adjustment Reason Code (CARC) or to convey information about remittance processing. Each RARC identifies a specific message as shown in the Remittance Advice Remark Code List. There are two types of RARCs, supplemental and informational. The majority of the RARCs are supplemental; these are generally referred to as RARCs without further distinction. Supplemental RARCs provide additional explanation for an adjustment already described by a CARC. The second type of RARC is informational; these RARCs are all prefaced with Alert: and are often referred to as Alerts. Alerts are used to convey information about remittance processing and are never related to a specific adjustment or CARC.
