N433 Remark Code - Resubmit Claim with NPI
The N433 remark code instructs the biller to resubmit the claim using only the National Provider Identifier (NPI). This indicates that the original submission likely included other identifiers that are not acceptable for processing by the payer.
How It Relates to the Denial
N433 typically accompanies a Claim Adjustment Reason Code (CARC) that indicates a claim was denied or adjusted due to incorrect provider identification. The combination signals that the claim must be revised to meet the payer's requirements for provider identification.
Common Scenarios
1A claim for a consultation was submitted with both the NPI and a legacy provider number, and the remittance returned with a denial for incorrect provider identification.
→ The N433 remark indicates that the payer requires the claim to be resubmitted using only the NPI, as other identifiers may have caused the denial.
2An outpatient procedure claim was submitted with the provider's tax identification number (TIN) alongside the NPI, resulting in a partial payment and an adjustment notice.
→ The N433 remark suggests that the claim should be corrected and resubmitted with just the NPI to comply with the payer's submission guidelines.
3A claim was denied for a missed appointment fee due to incorrect provider information, and the remittance included the N433 remark.
→ The N433 remark means the biller must remove any identifiers other than the NPI before resubmitting the claim for reconsideration.
What to Do
- Resubmit the claim using only the National Provider Identifier (NPI).
- Remove any other identifiers, such as the TIN or legacy provider numbers, from the claim submission.
What to Check
- Verify that the NPI is correctly listed on the claim form.
- Check the original claim submission for any additional identifiers that may have been included.
- Review the accompanying Claim Adjustment Reason Code to understand the context of the adjustment.
