    CPT 21720: Sternocleidomastoid Muscle Division for Torticollis

    Medicare pays $583 on average nationally for this procedure.

    CPT code 21720 describes open surgical division of the sternocleidomastoid muscle to treat congenital or acquired torticollis, a procedure performed to release neck muscle contracture that causes head tilt and abnormal neck posture; service type is surgical procedure (soft tissue release) and the typical site of service is an operating room or ambulatory surgery center where the surgeon performs the muscle division without application of a cast.

    Clinical & Coding Specifications

    Clinical Context

    A 6-year-old child presents to a pediatric otolaryngology clinic with persistent congenital muscular torticollis characterized by a fixed head tilt to the right, limited left neck rotation, and palpable tightness of the right sternocleidomastoid (SCM) muscle despite months of conservative therapy (physical therapy, stretching, and botulinum toxin where applicable). After multidisciplinary evaluation including physical exam and review of prior conservative management, the surgical plan is a selective open division (tenotomy or Z-plasty release) of the SCM to correct head posture and improve range of motion. The procedure is performed in an ambulatory surgery center under general anesthesia. The surgeon isolates and divides the affected SCM muscle without applying a postoperative cast. Intraoperative tasks include exposure of the SCM, division of the muscle (and possible fascial rearrangement), hemostasis, and layered wound closure; a small dressing is applied and the patient is observed in PACU for recovery and pain control before same-day discharge with instructions for postoperative physical therapy and wound care. Typical payors involved include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, BUCA, and Medicare depending on patient age and coverage type.
