CPT® Code 27005

The procedure described by CPT® Code 27005 refers to an open tenotomy of the hip flexor(s), which is classified as a separate procedure. A tenotomy is a surgical procedure that involves cutting a tendon to relieve tension or correct deformities. In this case, the focus is on the hip flexors, particularly the iliopsoas muscle, which is often implicated in severe flexion deformities. These deformities can arise from conditions such as spastic paraplegia or spastic cerebral palsy, where muscle tightness leads to an inability to fully extend the hip. The procedure begins with an evaluation of the flexion deformity, identifying the specific contractures that need to be addressed. The surgical approach involves making an incision over the iliopsoas tendon to expose it adequately. A complete tenotomy is then performed at the lesser trochanter, which is a bony prominence on the femur where the iliopsoas tendon attaches. In some cases, additional procedures may be necessary, such as releasing the hamstring tendons to address knee flexion deformities. This may involve incisions on the biceps femoris, semitendinosus, and/or semimembranosus tendons at the hip. After the surgical intervention, the operative incisions are meticulously closed in layers to promote healing, and casts or braces may be applied as needed to support recovery and maintain proper alignment.
