What 64610 covers
This service uses a neurolytic technique, such as chemical treatment or radiofrequency, to injure a targeted portion of the trigeminal nerve and reduce pain signaling. It is performed percutaneously by a clinician experienced in facial pain procedures, commonly in a procedural or facility setting. The target is selected from the patient's pain distribution and clinical findings; treatment may involve branches serving the midface or lower face.
Choose the code that matches the specific trigeminal target and procedure documented, rather than coding only from the diagnosis of facial pain or trigeminal neuralgia. The record should identify the treated nerve or branch, side, technique, and clinical rationale. The procedure has a 10-day global period, which includes related postoperative visits during that period. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard multiple procedure reduction. For bilateral treatment, modifier 50 is paid at 150%. Medicare does not pay an assistant at surgery for this procedure; co-surgeons and team surgery are not permitted.
