Common CARC pairings
RARCs like N389 ride alongside CARCs on the 835 electronic remittance advice. These are the CARC denials RARC N389 is most often paired with.
| CARC | Meaning |
|---|---|
| 16 | Claim/service lacks information or has submission/billing error(s). Usage: Do not use this code for claims attachment(s)/other documentation. At least one Remark Code must be provided (may be comprised of either the NCPDP Reject Reason Code, or Remittance Advice Remark Code that is not an ALERT.) Refer to the 835 Healthcare Policy Identification Segment (loop 2110 Service Payment Information REF), if present. |

| 175 | Prescription is incomplete. |
