N500 Remark Code - Incomplete Medical Legal Report

The N500 remark code indicates that the medical legal report submitted with the claim is incomplete or invalid. This remark supplements an adjustment already detailed by a Claim Adjustment Reason Code, providing additional context for the denial or reduction of payment.

How It Relates to the Denial

The N500 remark typically accompanies adjustment reason codes related to insufficient documentation or failure to meet required legal reporting standards. The combination signals that the claim cannot be processed further until the necessary documentation is corrected or provided.

Common Scenarios

1A claim was submitted for a patient’s surgical procedure, but the payment was reduced due to missing components in the medical legal report.
→ The N500 remark informs the biller that the payer found the medical legal report lacking in required details, indicating that the documentation must be reviewed and completed.
2A provider submitted a claim for a psychological evaluation, but received a denial with an adjustment reason code indicating invalid documentation and the N500 remark.
→ The N500 remark suggests that the medical legal report accompanying the claim did not meet the payer’s criteria, prompting the need for the provider to address the report's deficiencies.
3A physical therapy claim was denied with a reason code pointing to insufficient documentation, and the N500 was included in the remittance advice.
→ The N500 remark signals that the medical legal report was either not submitted or was deemed insufficient, which needs to be corrected for resubmission.

What to Do

  1. Review the medical legal report for completeness and accuracy.
  2. Gather any missing information that is required for the report.
  3. Resubmit the claim with the corrected medical legal report attached.

What to Check

  • The medical legal report submitted with the claim.
  • The claim adjustment reason code that accompanies the N500 remark.
  • Documentation guidelines provided by the payer regarding medical legal reports.
