CPT® Code 27307

The procedure described by CPT® Code 27307 refers to a percutaneous tenotomy involving multiple tendons of the adductor or hamstring muscles. A tenotomy is a surgical procedure that involves the cutting of a tendon to relieve tension or to correct deformities. In this specific case, the focus is on the hamstring muscles, which are comprised of three distinct muscles: the biceps femoris, semitendinosus, and semimembranosus. These muscles play a crucial role in knee extension and thigh flexion. Additionally, the adductor muscles, including the gracilis, are involved in thigh flexion and adduction. The procedure is particularly beneficial for patients with conditions such as cerebral palsy, where it aims to improve gait and alleviate flexion deformities of the knee. The tenotomy is performed percutaneously, meaning it is done through small incisions, minimizing tissue damage and promoting quicker recovery. This code is specifically used when multiple tendons are divided in one leg, distinguishing it from related procedures that may involve fewer tendons.
