What 15620 covers
This code covers a staged operation that delays a flap’s blood supply or sections a previously created flap, with division and inset. The covered sites are the face, scalp, neck, axilla, genitalia, hands, and feet. Plastic and reconstructive surgeons commonly perform this work in an operating room as part of staged reconstruction, such as preparing local tissue for later movement or completing a flap stage.
Select the code by the flap’s anatomic site, distinguishing these locations from the trunk, arms or legs, and eyelids, nose, ears, or lips. The operative report should identify the flap and site and describe the delay or sectioning, division, and inset performed. This major surgery code has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Medicare does not pay an assistant at surgery for this code; co-surgeons and team surgery are not permitted.
