N301 Remark Code - Missing Procedure Dates Explained

The N301 remark code indicates that the claim was adjusted due to missing, incomplete, or invalid procedure dates. This remark supplements the adjustment reason code provided in the remittance and clarifies that the procedure date is a specific issue affecting the claim's processing.

How It Relates to the Denial

The N301 remark code typically accompanies adjustment reason codes related to claim denials or reductions where the procedure date is a critical factor. This combination signals to the biller that the issue with the claim is directly tied to the dates associated with the procedures billed.

Common Scenarios

1A provider submitted a claim for a surgical procedure but did not include the date of service for the procedure. The payer returned the claim with an adjustment reason code indicating it was denied for this reason.
→ The appearance of the N301 remark code means the payer is specifically pointing out that the missing procedure date is the reason for the claim's denial, requiring correction before resubmission.
2A claim for a diagnostic test was submitted with an incorrect date that did not match the service record. The remittance response included a reason code for denial along with the N301 remark code.
→ The N301 remark indicates that the payer found the procedure date to be invalid, reinforcing that the date must be corrected to resolve the denial.
3A claim for a physical therapy session was submitted, but the procedure date was omitted. The remittance included a reason for denial along with the N301 remark code.
→ In this case, the N301 remark code highlights that the absence of the procedure date is the reason for the claim's adjustment, signaling the need for the date to be added for resubmission.

What to Do

  1. Review the submitted claim to ensure that the procedure date is included and accurately reflects the service provided.
  2. Correct any inaccuracies or omissions related to the procedure date before resubmitting the claim.
  3. If needed, consult the patient's medical records to verify the correct date of service for the procedures billed.

What to Check

  • The claim submission to ensure that the procedure date is clearly indicated and correct.
  • The patient's medical records for the accurate date of service associated with the procedure.
  • The payer's policy for additional requirements regarding procedure dates to avoid future issues.
