CPT® Code 27035

The procedure described by CPT® Code 27035 involves the denervation of the hip joint, specifically targeting the intrapelvic or extrapelvic intra-articular branches of the sciatic, femoral, or obturator nerves. The sciatic nerve originates from the sacral plexus, exiting the pelvis through the greater sciatic foramen and extending down the thigh along the posterior compartment. In contrast, the femoral and obturator nerves arise from the lumbar plexus, with the femoral nerve entering the thigh beneath the inguinal ligament and the obturator nerve traversing the pelvis to enter the thigh through the obturator canal. These nerves can become entrapped between the fascia, leading to significant pain and restricted range of motion in the hip joint. The denervation procedure aims to alleviate this pain by disrupting the nerve pathways that contribute to the discomfort. The approach can be intrapelvic, involving an incision in the lower abdomen to access the nerves, or extrapelvic, where an incision is made over the hip to directly access the affected nerves. In both cases, the procedure involves either dividing the nerve or destroying a portion of it to relieve symptoms associated with nerve entrapment.
