N631Remark Code (RARC)Active
N631 Remark Code - Medical Fee Schedule Explanation
The N631 remark code indicates that the billed procedure code is not found in the medical fee schedule. Instead, the payer has provided an allowance for a comparable service that is listed.
How It Relates to the Denial
Typically, the N631 remark code appears alongside a Claim Adjustment Reason Code that indicates a denial or reduction based on fee schedule criteria. This combination signals that while the specific code was not covered, a similar service was recognized for reimbursement.
Common Scenarios
1A provider billed for a specific procedure code not listed in the payer's fee schedule, such as a unique therapy service, and received an adjustment on the remittance advice.
→ The N631 remark code clarifies that although the billed code is not recognized, the payer has adjusted the claim based on a similar service that is covered.
2A claim for a new diagnostic code was submitted, but the remittance response indicated an adjustment with a reason code for non-coverage.
→ The appearance of the N631 remark code suggests that the payer does not recognize the specific diagnostic code but has compensated for a related code that is included in their fee schedule.
3A provider submitted a claim for a specialized surgical procedure not typically covered, resulting in a partial payment noted in the remittance.
→ The N631 remark code indicates that while the surgical procedure code was not listed, the payer allowed payment based on a comparable procedure that does have coverage.
What to Do
- Review the explanation of benefits (EOB) for the original claim adjustment reason code.
- Verify that the billed code is indeed not listed in the payer's medical fee schedule.
- Consider resubmitting the claim with a different, covered procedure code if appropriate.
What to Check
- The payer's medical fee schedule to confirm the status of the billed procedure code.
- The claim adjustment reason code that accompanies the N631 remark code for full context.
- Documentation supporting the medical necessity of the service provided, in case of further appeals.
