How to use RARC N517
RARC N517 should be read with the CARC and group code on the same claim or service line. For BCBS denials, the remark often tells you whether the next move is a corrected claim, attachment response, COB update, authorization proof, or appeal packet.
Common paired CARCs
Recommended workflow
- Read the line-level CARC, group code, and every non-alert RARC attached to the denial line.
- Compare the denied line against the 837 claim image, clearinghouse acceptance, eligibility response, authorization record, and provider enrollment record.
- Fix the specific field that the RARC or EOB identifies. Do not resubmit a clone of the rejected claim.
- Use corrected-claim frequency and original claim number requirements from the applicable local Blue plan.
- Appeal only when the claim already contained the required information and the payer edit appears incorrect.
Evidence checklist
