Modifier 78: Unplanned return to operating room
CPT defines Modifier 78 as “an unplanned return to the operating/procedure room by the same physician following the initial process for a related procedure during the postoperative period.” When this process is related to the first and necessitates using an operating or procedure room, add modifier 78 to the related procedure.” That is care provided due to the original surgery, not due to the original condition. The idea is to use modifier 78 for a related procedure that wasn’t scheduled ahead of time. A biopsy is performed by a surgeon, for example. The wound becomes infected, necessitating a second procedure to remove the infection.
