N300 Remark Code - Missing or Invalid Occurrence Dates
The N300 remark code indicates that there are missing, incomplete, or invalid occurrence span dates on the claim. This remark supplements a Claim Adjustment Reason Code, providing further detail about the specific issue with the dates submitted.
How It Relates to the Denial
The N300 remark code typically accompanies adjustment reason codes related to claim denials or reductions due to date discrepancies. The combination signals that the payer has identified an issue specifically with the occurrence span dates that needs to be addressed for correct processing.
Common Scenarios
1A provider submits a claim for a series of physical therapy sessions but receives a denial indicating that the occurrence span dates are missing.
→ The N300 remark code clarifies that the payer requires specific occurrence span dates to process the claim correctly. The biller must ensure that these dates are included and accurately reflect the service period.
2A claim for a surgical procedure is returned with an adjustment reason code saying 'dates of service not valid,' and N300 is included in the remittance advice.
→ With the N300 remark, it is clear that the occurrence span dates provided with the claim are either incomplete or invalid. The payer expects the biller to review and correct these dates.
3An outpatient claim for diagnostic testing is submitted, but the remittance shows a denial with N300, stating the occurrence span dates are invalid.
→ The presence of the N300 remark indicates that the payer found issues with the dates indicating when the services occurred. The biller needs to verify and correct the occurrence span dates for resubmission.
