What 21705 covers

This open operation removes sternocleidomastoid muscle tissue to release persistent restriction, most commonly in a patient with congenital muscular torticollis. The surgeon works through the neck to resect the involved muscle; the operative report should identify the muscle treated and describe the excision. The service is generally performed in an operating room rather than an office setting.

Select this code when the documented procedure is muscle resection, not simply division or release, and distinguish it from repair or reconstruction of a congenital muscle abnormality. The operative note should support the indication, side, extent of resection, and work performed. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For bilateral reporting with modifier 50, payment is at 150%. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and others at 50%. An assistant at surgery may be paid; co-surgeons and team surgery are not permitted.
