What 64734 covers
This service involves intentionally dividing or avulsing the infraorbital nerve, a sensory nerve that supplies the cheek and upper lip. A surgeon may perform it for selected patients with persistent infraorbital neuralgia or painful nerve injury when sacrificing the nerve is part of the treatment plan. It is generally performed in an operative setting by a surgeon such as an oral and maxillofacial, plastic, or otolaryngologic surgeon.
Report the code when the operative record identifies the infraorbital nerve and documents its transection or avulsion, the treated side, and the clinical reason for the procedure. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. For bilateral surgery, modifier 50 is paid at 150%. Assistant-at-surgery payment requires documentation of medical necessity; co-surgeons and team surgery are not permitted.
