N321 Remark Code - Missing Last Admission Period Explained
The N321 remark code indicates that there is a missing, incomplete, or invalid last admission period associated with the claim. This code supplements an adjustment already described by a Claim Adjustment Reason Code, providing additional detail on the nature of the issue affecting the claim's payment.
How It Relates to the Denial
The N321 remark code typically accompanies reason codes related to claim adjustments that involve admission or inpatient stay details. The combination signals that the payer needs more accurate information about the patient's last admission period to process the claim correctly.
