About 64583: Hypoglossal stimulator system revision or replacement
Revision or replacement of an implanted hypoglossal nerve stimulation array and pulse generator, generally performed to address a problem with an existing system.
This operating-room service revises or replaces an implanted hypoglossal nerve stimulation array and pulse generator. It is typically performed by an otolaryngologist or another surgeon experienced with hypoglossal nerve stimulation for obstructive sleep apnea. The work concerns an existing system, rather than the initial implantation used to treat a patient with sleep-disordered breathing.
Report 64583 when the operative work revises or replaces the hypoglossal array and pulse generator; document the existing device, the reason for the procedure, and the components addressed. The code has a 90-day global period, which includes the day-before preoperative visit and related postoperative care during that period. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery, co-surgeon, and team-surgery payment requires supporting documentation; an assistant also requires documentation of medical necessity.
