N329 Remark Code: Missing Patient Birth Date

The N329 remark code indicates that the claim has a missing, incomplete, or invalid patient birth date. This code supplements a Claim Adjustment Reason Code that addresses the same issue, providing further clarification to the biller about the nature of the discrepancy.

How It Relates to the Denial

The N329 remark code typically accompanies adjustment reason codes that signal issues with patient information. When this code appears, it suggests that the claim is being denied or adjusted due to problems specifically related to the patient's birth date details.

Common Scenarios

1A provider submitted a claim for a routine office visit, but the remittance report includes N329 along with a reason code indicating a denial due to incomplete patient demographics.
→ The appearance of N329 means the payer found that the patient's birth date was either not provided or was incorrectly formatted, which needs to be corrected for the claim to be processed.
2A claim for a surgical procedure was returned with N329 shown alongside an adjustment reason code for incorrect patient data.
→ In this scenario, N329 indicates that the patient's birth date was missing or invalid, which must be rectified to resolve the denial associated with the claim.
3An emergency room visit was billed, but the remittance statement reflects N329 with a reason code related to patient information errors.
→ This remark code signifies that the payer could not verify the patient's identity due to an issue with the provided birth date, necessitating a review of the submitted information.

What to Do

  1. Review the patient record to confirm the birth date is accurately documented.
  2. Correct any discrepancies found in the patient birth date on the claim.
  3. Resubmit the claim with the updated patient birth date information.

What to Check

  • Verify the patient's birth date in the medical record.
  • Check the claim submission for the correct format of the birth date.
  • Consult the eligibility response to ensure the birth date matches the payer's records.
