In simple words: This procedure addresses groin pain by surgically interrupting the obturator nerve in the hip/thigh region. The surgeon makes an incision to access the nerve and either cuts or removes a portion of it. Sometimes, the tendon of a nearby muscle (the adductor muscle) is also released.

This procedure involves severing or removing a part of the obturator nerve outside the pelvis. It is performed to alleviate groin pain caused by nerve damage or entrapment. The procedure may also include releasing the adductor tendon.

Example 1: A patient experiences chronic groin pain due to entrapment of the obturator nerve. Conservative treatments have failed, and the patient undergoes a transection of the obturator nerve (64763) to relieve the pain., A patient with a history of trauma to the hip presents with persistent groin pain and weakness in thigh adduction. Imaging reveals damage to the obturator nerve. An avulsion of the damaged portion of the obturator nerve (64763) is performed., A patient with spasticity in the adductor muscles undergoes an obturator neurotomy (64763) combined with an adductor tenotomy to improve range of motion and reduce pain.

Documentation should include details of the patient's symptoms, physical exam findings, imaging results (if applicable), prior conservative treatments, and medical necessity for the procedure. Operative reports should describe the surgical technique, including whether a transection or avulsion was performed and if an adductor tenotomy was also done.
