N345Remark Code (RARC)Active
N345 Remark Code - Date Range Not Valid
The N345 remark code indicates that the date range provided on the claim does not align with the units submitted for the service. This suggests that the billed units may not correspond to the dates of service indicated, which can lead to payment discrepancies.
How It Relates to the Denial
The N345 remark code typically accompanies a claim adjustment reason code that indicates an adjustment due to billing errors related to date discrepancies. This combination signals that the payer is addressing issues specifically tied to the accuracy of the dates of service and the corresponding units billed.
Common Scenarios
1A provider bills for physical therapy services for 10 units over a date range of January 1 to January 10, but the payer returns a remittance with the N345 remark code.
→ In this case, the N345 remark suggests that the payer found the units billed do not match the expected service frequency for the specified date range.
2A hospital submits a claim for laboratory tests performed from February 1 to February 5, with 5 units billed, but receives the N345 remark code on the remittance advice.
→ Here, the N345 remark indicates that the number of units billed is inconsistent with the date range provided, prompting a review of the claim for accuracy.
3A surgery center submits a claim for 3 units of a procedure performed over a date range from March 1 to March 3, and the remittance shows the N345 remark code.
→ The N345 remark implies that the payer questions the validity of the units in relation to the service dates, suggesting a potential error in the claim submission.
