N148 Remark Code: Missing Date of Last Menstrual Period
The N148 remark code indicates that the claim has a missing, incomplete, or invalid date of the last menstrual period. This code supplements a Claim Adjustment Reason Code, providing additional context for the adjustment made by the payer.
How It Relates to the Denial
The N148 remark typically accompanies adjustment reason codes related to maternity or gynecological services. The combination signals that the payer requires accurate date information to process claims correctly.
Common Scenarios
1A claim for a prenatal visit was submitted, but the payer returned it with an adjustment indicating a lack of necessary information.
→ The N148 remark suggests that the claim was denied due to the absence or inaccuracy of the date of the last menstrual period, which is essential for determining the patient's eligibility for the service.
2Billing for a gynecological exam included a date of last menstrual period, but the payer flagged the claim for review, resulting in an adjustment notice.
→ In this case, the N148 remark points to potential discrepancies in the date provided, indicating that the payer could not validate the information needed for proper claim adjudication.
3A claim for a delivery service was denied, and the remittance included an adjustment reason code along with the N148 remark.
→ The presence of the N148 remark indicates that the payer found the date of the last menstrual period to be missing or invalid, which is critical for processing the delivery claim correctly.
