Common CARC pairings
RARC N227 appears with a Claim Adjustment Reason Code (CARC) on the 835 electronic remittance advice and gives more detail about the adjustment. These are the CARCs most often paired with RARC N227.
| CARC | Meaning |
|---|---|
| 50 | These are non-covered services because this is not deemed a 'medical necessity' by the payer. Usage: Refer to the 835 Healthcare Policy Identification Segment (loop 2110 Service Payment Information REF), if present. |
| 251 | The attachment/other documentation that was received was incomplete or deficient. The necessary information is still needed to process the claim. 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). |
