N389 Remark Code - Duplicate Prescription Number
The N389 remark code indicates that a duplicate prescription number has been submitted for the claim. This suggests that the payer has identified that the prescription number listed on the claim matches a previously processed claim, resulting in a denial or adjustment based on this duplication.
How It Relates to the Denial
Typically, the N389 remark code accompanies a claim adjustment reason code that indicates a denial or adjustment due to duplicate claims. The combination signals to the biller that the submitted prescription information needs to be reviewed for accuracy and uniqueness.
Common Scenarios
1A pharmacy submits a claim for a medication refill, but the remittance shows an adjustment for a duplicate prescription number.
→ In this case, the N389 remark code indicates that the prescription number used for the refill matches one that has already been processed, prompting the need for verification of the prescription details.
2A provider bills for a patient’s medication, but the payer returns a remittance with an adjustment indicating the prescription number is a duplicate.
→ The presence of the N389 remark code means the payer sees the prescription number as already submitted for a previous claim, suggesting there may have been an error in submission.
3A claim for a new prescription is submitted, yet the remittance indicates a denial due to a duplicate prescription number.
→ Here, the N389 remark code alerts the biller that the prescription number conflicts with an earlier claim, indicating the need to check for correct and unique prescription entries.
What to Do
- Verify the prescription number submitted on the claim against previous submissions.
- Ensure that the prescription number is unique and not reused for different claims.
- If the prescription was indeed a duplicate, consider correcting the claim or discussing with the prescribing provider.
What to Check
- The claim submission records for the prescription number in question.
- The patient's medication history to confirm if the prescription has been previously filled.
- Any prior remittances that may detail the original claim associated with the duplicate prescription number.
