CARC Lookup
The Claim Adjustment Reason Code (CARC) Lookup allows Trading Partners to view descriptions of CARC codes that are valid for the submission of Encounter Data. The CARC code is submitted on the ASC X12 837 in the CAS02 segment of Loop ID 2320 or Loop ID 2430. The lookup allows you to enter the CARC code and will return a description of the code.
The Claim Adjustment Reason Codes are maintained by X12 formerly known as ASC X12 EDI (Accredited Standards Committee X12, Electronic Data Interchange).
