CPT® Code 27110

The procedure described by CPT® Code 27110 involves the surgical transfer of the iliopsoas muscle to the greater trochanter of the femur. This operation is typically indicated for patients suffering from congenital hip dislocation or paralysis affecting the hip adductor muscles. The iliopsoas muscle, which plays a crucial role in hip flexion and stabilization, is accessed through an anterolateral incision made over its insertion point on the lesser trochanter. During the procedure, the iliopsoas is carefully divided at its insertion, allowing for the creation of a notch in the wing of the ilium, situated between the anterior superior and anterior inferior iliac spines. This notch facilitates the passage of the iliopsoas muscle through the ilium and subsequently through a split in the gluteus medius and minimus muscles. Once properly positioned, the iliopsoas is secured to the greater trochanter or femoral neck, depending on the specific surgical approach. It is important to note that CPT® Code 27110 is specifically used when the iliopsoas is transferred to the greater trochanter, while CPT® Code 27111 is designated for transfers to the femoral neck.
