Peripheral nerve surgery
About 64736: Mental nerve transection or avulsion
Reports surgical interruption of the mental nerve, a sensory nerve serving the chin and lower lip, for a documented operative indication.
This procedure deliberately interrupts the mental nerve, a terminal sensory branch of the trigeminal nerve that supplies sensation to the chin and lower lip. It may be performed by an oral and maxillofacial surgeon or another surgeon treating a documented condition involving this nerve, generally in an operating room. The operative target is the mental nerve itself, not a nearby cheek, jaw, or tongue nerve.
Report the code when the operative record supports intentional division or avulsion of the mental nerve; document the side, nerve treated, indication, and technique. The service has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For bilateral surgery reported with modifier 50, CMS pays at 150%. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are paid at 50%. An assistant at surgery may be paid; co-surgeons and team surgery are not permitted.

64736 billing questions
How is this different from the cheek nerve procedure?
This code is for the mental nerve supplying the chin and lower lip. The cheek nerve code, 64734, targets the infraorbital nerve.
When would 64738 be more appropriate?
Use 64738 when the operative target is the jaw nerve rather than the mental nerve. The operative note should identify the specific nerve treated.
What documentation supports reporting this code?
Document the indication, the mental nerve as the operative target, the side, and the action performed. The record should distinguish intentional nerve interruption from work on a neighboring nerve.
How should bilateral mental nerve surgery be reported?
Report bilateral surgery with modifier 50. CMS pays the bilateral procedure at 150%.
Does the global period include related postoperative care?
Yes. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
