N666 Remark Code - E/M Coverage Limitation Explained
The N666 remark code indicates that only one evaluation and management (E/M) code at a specific service level is covered during the course of care. This means that the payer is informing you that multiple claims for E/M services at the same level are not eligible for reimbursement within the course of treatment.
How It Relates to the Denial
The N666 remark code typically accompanies a Claim Adjustment Reason Code that indicates a denial or adjustment for multiple E/M services billed for the same patient encounter. Together, these codes signal that the payer has limited coverage for E/M services during a defined care period.
Common Scenarios
1A provider submits claims for two separate E/M visits for a patient on the same day, both coded as level 3 services. The remittance shows an adjustment for one of the visits.
→ The N666 remark code clarifies that the payer will only cover one E/M service at that level for the patient's course of care, leading to the denial of the second claim.
2A clinic bills for three E/M codes over the course of a week for a patient receiving ongoing treatment. The remittance shows adjustments for two of the codes.
→ The appearance of the N666 remark code indicates that the payer restricts coverage to one E/M service at the same level during this treatment period, explaining the adjustments.
3A physician's office bills for an E/M service and later submits a follow-up E/M service for the same issue within a short timeframe. The remittance reflects an adjustment with the N666 remark.
→ The N666 remark code signifies that the payer only allows one E/M service at that level for the ongoing issue, leading to the adjustment of the follow-up claim.
What to Do
- Review the billed E/M codes to confirm they are at the same service level.
- Consider resubmitting only the covered E/M service if applicable, based on the payer's policy on multiple visits.
- Communicate with the provider about the limitation imposed by the payer for E/M services during the course of care.
What to Check
- The claim adjustment reason code accompanying the N666 remark for specific details on the adjustment.
- The documentation supporting the necessity of multiple E/M services submitted on the claim.
- The payer's policy on coverage limitations for E/M services during a course of care.
