Summary
This policy reissue clarifies the proper use of CPT Modifier 78 for unplanned returns to the operating or procedure room by the same physician or other qualified health care professional for a related procedure during the postoperative period. This is a reissue of existing policy (effective 03/05/2025), likely with clarifications or updates to modifier application guidelines. Billing teams must ensure claims for unplanned return procedures are correctly coded with Modifier 78 to avoid denials.
Action Required
By 03/05/2025: Billing team must review the complete policy text at the provided URL to identify specific coding requirements and any changes from the prior version. Update claim scrubbing rules in billing software to ensure Modifier 78 is applied correctly to unplanned return procedures. Coordinate with providers and clinical staff to document which procedures qualify as unplanned returns related to the initial procedure. Audit recent claims (last 30 days) coded with Modifier 78 to verify compliance with the reissued policy. Flag any discrepancies to providers for corrective action on future claims. Without proper Modifier 78 application, claims for legitimate unplanned return procedures may be denied or incorrectly processed.
