CPT® Code 27001

The procedure described by CPT® Code 27001 refers to an open tenotomy of the adductor muscle of the hip. The adductor muscle group is situated on the medial, or inner, side of the hip joint and plays a crucial role in the movement and stabilization of the hip. An adductor tenotomy is a surgical intervention that involves cutting the tendon of the adductor muscle to relieve conditions such as congenital hip dislocation or adduction contracture, which may occur in patients with spastic type cerebral palsy. This procedure is particularly indicated when there is a need to correct the positioning of the femoral head within the acetabulum, the socket of the hip joint. Unlike the percutaneous approach described in CPT® Code 27000, which involves a minimally invasive technique with a stab incision, the open tenotomy performed under CPT® Code 27001 requires a larger incision to directly access and expose the tendon. Following the incision, the adductor tendon is carefully incised, allowing for the repositioning of the femoral head into the acetabulum. After the procedure, the patient is typically placed in a hip spica cast to immobilize the hip joint and facilitate proper healing.
