N657Remark Code (RARC)Active
N657 Remark Code - Appropriate Code Required
The N657 remark code indicates that the billed services did not use the correct procedure code. This remark serves as guidance for the biller to ensure that the appropriate code is submitted for the services provided, as per the payer's requirements.
How It Relates to the Denial
The N657 remark code typically accompanies adjustment reason codes related to incorrect coding or billing errors. This combination signals that the claim was adjusted due to improper coding, necessitating a review of the procedure codes used on the claim.
Common Scenarios
1A provider submitted a claim for a physical therapy session but used a general therapy code instead of a specific code for the type of therapy provided. The remittance shows the N657 remark code alongside an adjustment reason code for incorrect coding.
→ In this case, the N657 remark code suggests that the billing office needs to identify and submit the specific code that accurately represents the therapy service rendered.
2A claim for a diagnostic test was submitted with a code that was not recognized for the specific test performed. The payer returns the claim with an adjustment reason code for non-covered services, along with the N657 remark code.
→ The N657 remark code indicates that the test should have been billed with a code that is appropriate for the service rendered, implying that the biller must review coding guidelines for the diagnostic test.
3A claim for a surgical procedure was denied because an outdated code was used. The remittance includes an adjustment reason code for billing errors and the N657 remark code.
→ This suggests that the surgical procedure should be billed with the updated and appropriate code, and the billing office needs to verify the current coding requirements for that surgery.
What to Do
- Review the procedure codes submitted on the claim for accuracy.
- Identify the correct code that should have been used for the services provided.
- Resubmit the claim with the corrected code to avoid future denials.
What to Check
- The billing guidelines for the specific services to ensure compliance with coding rules.
- The original claim submission to confirm which codes were used and how they align with the services.
- Payer-specific coding policies or updates that may affect the appropriateness of the codes billed.
