About 27100: Abdominal muscle transfer to thigh

Reports an operation that relocates abdominal muscle to the thigh, typically to restore hip or thigh function affected by paralysis.

The surgeon mobilizes abdominal muscle and reroutes it to the thigh to provide a new source of muscle function, commonly as reconstructive treatment for a paralytic hip. The operative report should identify the donor muscle, its new attachment, the side treated, and the functional problem prompting the transfer. This is an uncommon facility-based operation rather than a routine office procedure.

Report 27100 when the abdominal muscle transfer itself is performed; distinguish it from transfers using spinal or iliopsoas muscle. The 90-day major-surgery global period includes the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Bilateral reporting with modifier 50 is paid at 150%. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
