About 64584: Hypoglossal stimulator system removal
Reports surgical removal of an implanted hypoglossal nerve stimulation array and pulse generator, commonly performed when an obstructive sleep apnea device must be explanted.
This operation removes the implanted hypoglossal nerve stimulation system, including its electrode array and pulse generator. It is typically performed by an otolaryngologist or another surgeon experienced in sleep-related airway procedures, usually in an operating room. The system is used to stimulate the hypoglossal nerve during sleep for selected patients with obstructive sleep apnea; removal may be needed when the device must be explanted rather than revised or replaced.
Report 64584 when the procedure removes the hypoglossal array and pulse generator, not for initial implantation or revision/replacement. The operative report should identify the hypoglossal system and document the components removed. CMS assigns a 90-day global period, including 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% reduction. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery, co-surgeon, and team-surgery payment require the applicable supporting documentation.
