What 64866 covers

This operation redirects motor input to the face by connecting the facial nerve to the spinal accessory or hypoglossal nerve. It is used in selected cases of facial paralysis when the native facial nerve pathway cannot provide useful function. A surgeon with microsurgical nerve expertise, often in otolaryngology, facial plastic and reconstructive surgery, plastic surgery, or neurosurgery, performs the nerve coaptation, generally in an operating room.

Select this code when the operative report identifies the facial nerve and one of these specific donor nerves as the anastomosis partners. Documentation should establish the paralysis indication, relevant nerve anatomy and findings, and the procedure performed. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. 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 50% reduction. Modifier 50 is inappropriate for this service. An assistant at surgery may be paid; co-surgeons require supporting documentation, and team surgery is not permitted.
