N350 Remark Code - Service Description Issues
The N350 remark code indicates that there is a missing, incomplete, or invalid description of service associated with a Not Otherwise Classified (NOC) code or an Unlisted/By Report procedure. This remark supplements an adjustment reason code by specifying that additional details about the service description are necessary for proper processing.
How It Relates to the Denial
The N350 remark typically accompanies adjustment reason codes that indicate a claim has been denied or reduced due to insufficient information. This combination signals that the payer requires a more detailed service description to proceed with the claim.
Common Scenarios
1A provider submits a claim for an unlisted surgical procedure but receives a denial with a reason code indicating insufficient documentation.
→ The N350 remark suggests that the payer needs a complete and accurate description of the procedure performed to evaluate the claim correctly.
2A claim for a Not Otherwise Classified (NOC) code is submitted, but the remittance shows a reduction in payment due to a lack of service detail.
→ The presence of the N350 remark indicates that the payer requires more information about the service to justify the reimbursement amount.
3A biller receives an 835 remittance for a complex procedure with a vague description submitted under an unlisted code, and the N350 remark appears.
→ This remark signals that the description provided was not adequate for the payer’s review process, necessitating a more thorough explanation.
What to Do
- Review the service description submitted with the claim to ensure it is complete and accurate.
- If necessary, provide a detailed narrative of the procedure performed under the unlisted or NOC code to the payer.
- Resubmit the claim with the corrected service description, ensuring compliance with payer requirements.
What to Check
- The claim documentation to confirm the accuracy of the service description provided.
- The payer's policy guidelines regarding the use of unlisted and NOC codes.
