N479 Remark Code - Missing Explanation of Benefits
The N479 remark code indicates that there is a missing Explanation of Benefits (EOB) related to Coordination of Benefits (COB) or Medicare Secondary Payer (MSP) situations. This remark supplements an adjustment already explained by a Claim Adjustment Reason Code, clarifying that the payer requires an EOB to process the claim correctly.
How It Relates to the Denial
The N479 remark typically accompanies adjustment reason codes that involve COB or MSP issues, signaling that the payer expects additional documentation to verify benefits coordination. It helps to clarify the need for an EOB to support the claim adjustment made.
Common Scenarios
1A provider submitted a claim for a patient who has both Medicare and a commercial insurance plan. The remittance shows an adjustment for a claim denial due to lack of primary payer information, accompanied by the N479 remark.
→ In this case, the N479 remark is indicating that the payer cannot proceed with the claim because the EOB from the primary payer (Medicare) is missing, which is needed for proper coordination of benefits.
2A claim was submitted for a service rendered to a patient with dual coverage. The remittance received includes a denial with an adjustment reason code and the N479 remark indicating missing documentation.
→ Here, the N479 remark highlights that the payer requires the EOB from the other insurance to determine the correct payment amount based on the coordination of benefits.
3A facility billed for a procedure for a Medicare beneficiary who also has Medicaid. The remittance returned indicates a payment adjustment with the N479 remark present.
→ This suggests that the payer is missing the Medicaid EOB, which is necessary to finalize the payment process according to the coordination of benefits rules.
What to Do
- Obtain the missing Explanation of Benefits from the primary payer.
- Ensure that the EOB is clearly marked with the necessary details regarding payment and coordination.
- Resubmit the claim with the EOB attached to support the adjustment.
What to Check
- The remittance advice for the accompanying reason code for context on the adjustment.
- The claim submission records to verify if the EOB was included initially.
- The primary payer's EOB to ensure it has been received and is complete.
