What 27005 covers
An orthopedic surgeon makes an incision to reach and divide a hip-flexor tendon, reducing excessive tension or a fixed flexion contracture. The iliopsoas is a typical target. The procedure may be performed for contracture associated with neuromuscular conditions, including cerebral palsy, in an operating-room setting. The open approach distinguishes this service from a percutaneous release.
Report 27005 when the operative work is an open release of a hip flexor, not an adductor, abductor, or extensor tendon. The operative note should identify the treated tendon, side, open approach, and clinical reason for release. 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 the same session, the highest-valued procedure is paid in full and others at 50%. Bilateral reporting with modifier 50 is paid at 150%. An assistant at surgery may be paid; co-surgeons require supporting documentation, and team surgery is not permitted.
