CPT® Code 64732

Transection or avulsion of the supraorbital nerve, as described by CPT® Code 64732, refers to a surgical procedure that involves the severing and/or removal of a portion of the supraorbital nerve. This procedure is primarily performed to alleviate chronic pain conditions. The supraorbital nerve is a significant branch of the frontal nerve, which is responsible for sensory innervation to specific areas of the forehead and upper eyelid. It exits the skull through the supraorbital foramen or groove, providing palpebral filaments that supply the upper eyelid and further divides into medial and lateral branches that innervate the scalp. The surgical approach typically involves making an incision over the eyebrow, followed by careful dissection of the soft tissues to expose the supraorbital nerve as it exits the foramen. The nerve is then isolated, and various techniques may be employed to transect or avulse it, which may include the use of a rongeur to enhance visibility and access. This procedure is indicated for patients suffering from conditions that warrant the interruption of nerve function to manage pain effectively.
