N451 Remark Code - Missing Admission Summary Report
The N451 remark code indicates that an Admission Summary Report is missing from the documentation submitted with a claim. This remark supplements a Claim Adjustment Reason Code and signals that the payer requires this specific report to process the claim accurately.
How It Relates to the Denial
The N451 remark typically accompanies adjustment reason codes related to documentation deficiencies. It indicates that the claim has been adjusted due to the absence of essential information needed for review.
Common Scenarios
1A hospital submits a claim for an inpatient stay but receives a remittance that includes a Claim Adjustment Reason Code for lack of documentation.
→ The N451 remark points out that the claim cannot be processed further because the required Admission Summary Report was not included.
2A patient is billed for a surgical procedure following an inpatient admission, but the remittance shows an adjustment due to missing documentation.
→ The presence of N451 indicates that the payer is specifically looking for the Admission Summary Report to support the claim.
3A facility submits claims for multiple admissions but receives a denial indicating missing documentation for one specific admission.
→ The N451 remark suggests that the Admission Summary Report for that particular admission is required for the claim to be reconsidered.
What to Do

What to Check
