N456 Remark Code - Incomplete/Invalid Physician Order
The N456 remark code indicates that the physician order associated with the claim is incomplete or invalid. This remark supplements a Claim Adjustment Reason Code, providing additional context for the denial or adjustment related to the physician's order.
How It Relates to the Denial
The N456 remark code typically accompanies reason codes that indicate a claim was denied or adjusted due to issues with the physician order. This combination signals that the payer found deficiencies in the order that need to be addressed before resubmission.
Common Scenarios
1A claim for a diagnostic test was submitted, but the remittance returned with a denial indicating the physician order was not properly completed.
→ In this scenario, the N456 remark code points to the need for a complete and valid physician order. The payer expects the biller to review the order for any missing or incorrect information.
2A claim for a surgical procedure was denied because the physician's order did not specify the correct procedure details.
→ The presence of the N456 remark code suggests that the physician order lacked necessary information. The payer is indicating that clarification or correction is required for the claim to be processed.
