Common RARC pairings
RARCs (Remittance Advice Remark Codes) provide the specific reason detail alongside CARC 284 on the 835 electronic remittance. These are the RARCs seen most often with this CARC.
| RARC | Meaning |
|---|---|
| M62 | Missing/incomplete/invalid treatment authorization code. |
| MA130 | Your claim contains incomplete and/or invalid information, and no appeal rights are afforded because the claim is unprocessable. Please submit a new claim with the complete/correct information. |
| N517 | Resubmit a new claim with the requested information. |
| N752 | Missing/incomplete/invalid HIPPS Treatment Authorization Code (TAC). |
