Unrelated Procedure or Service by the Same Physician During the Postoperative Period:

The physician may need to indicate that the performance of a procedure or service during the postoperative period was unrelated to the original procedure. This circumstance may be reported by using the modifier ‘-79’. (For repeat procedures on the same day, see ‘-76’).

Usage
