N328 Remark Code - Oxygen Saturation Test Date Issue
The N328 remark code indicates that the claim has missing, incomplete, or invalid information regarding the date of the Oxygen Saturation Test. This code supplements a Claim Adjustment Reason Code, providing additional context for the adjustment related to the claim.
How It Relates to the Denial
The N328 code typically accompanies adjustment reason codes that highlight issues with claim details, particularly those reflecting insufficient or incorrect documentation. This combination signals to the biller that the date for the Oxygen Saturation Test needs attention to resolve the claim issue.
Common Scenarios
1A claim was submitted for a patient’s pulmonary function tests that included an Oxygen Saturation Test, but the remittance returned with an adjustment indicating missing information.
→ The N328 remark suggests that the date for the Oxygen Saturation Test was not provided or was incorrectly entered, which is causing the adjustment on the claim.
2A provider's office submitted a claim for a comprehensive metabolic panel that included an Oxygen Saturation Test, but the denial highlighted an invalid date for the test.
→ In this case, the N328 remark points to an issue with the date submitted for the Oxygen Saturation Test, indicating that the claim cannot be processed without correcting this detail.
