What 15770 covers
This procedure uses a composite graft containing dermis, subcutaneous fat, and fascia to restore volume or reinforce deficient soft tissue. Plastic and reconstructive surgeons may use it when a defect or contour problem calls for this combination of tissues rather than a skin-only graft, a fat-only graft, or a flap. The operative record should identify the graft tissue, the recipient area, and the reconstructive purpose.
Report the code for the derma-fat-fascia graft service, with documentation supporting why this graft type was selected and describing the operative work. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in one session, the highest-valued procedure is paid in full and the others are subject to the standard 50% reduction. Modifier 50 is inappropriate for this code. Assistant-at-surgery payment may be allowed; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
