Summary
This policy reissue clarifies the correct use of CPT Modifier 79 for billing unrelated procedures or services performed by the same physician during a patient's postoperative period. The reissue (effective 03/05/2025) provides updated guidance on when Modifier 79 should be appended to distinguish an unrelated service from the global surgical package, ensuring proper claim adjudication and reimbursement.
Action Required
By March 5, 2025: Billing and coding team must review and implement the updated Modifier 79 guidance in their coding practices and billing system edits. Providers should be notified of the reissued policy requirements through staff meetings or email communication. Update internal coding guidelines and training materials to reflect the current policy. Ensure claims are coded according to the new policy to avoid denials or delays in payment for unrelated postoperative procedures.
