Summary
This policy reissue (effective 03/05/2025) clarifies the proper use of Modifier 78 for unplanned returns to the operating/procedure room by the same or other qualified provider for a related procedure during the postoperative period. Billing teams must ensure accurate modifier application to avoid claim denials and ensure appropriate reimbursement for legitimate unplanned return procedures.
Action Required
By 03/05/2025: Billing team must review and update modifier 78 coding guidelines in billing software and provider training materials. Ensure all coders understand when Modifier 78 applies (unplanned returns during postoperative period for related procedures). Audit recent claims (past 30-60 days) for modifier 78 usage to verify compliance with updated policy. Communicate with providers and surgical staff to clarify which procedures qualify for modifier 78 billing. Update claim submission templates and coder worksheets to include modifier 78 decision logic. Failure to apply modifier 78 correctly may result in claim denials or improper reimbursement.
