CPT® Code 27098

The procedure described by CPT® Code 27098 involves the surgical transfer of the adductor muscles, specifically the adductor longus and brevis, to the ischium. These muscles are situated on the medial, or inner, side of the hip joint and play a crucial role in the movement and stabilization of the hip. The transfer is typically indicated for patients suffering from adduction contracture, which is a condition characterized by the tightening of the muscles that leads to an abnormal inward positioning of the hip. This condition can be particularly prevalent in individuals with spastic type cerebral palsy, where muscle spasticity can result in subluxation, or partial dislocation, of the hip joint. The surgical intervention aims to alleviate the contracture and improve hip function by repositioning the tendons of the adductor muscles. The procedure begins with a skin incision made in the medial aspect of the groin, allowing access to the adductor longus tendon, which is then exposed, divided, and transferred to the ischial tuberosity. The adductor brevis may also be addressed in a similar manner, ensuring comprehensive treatment of the affected musculature.
