What 64570 covers
This operation removes the implanted electrode array from the vagus nerve and the associated pulse generator. It is typically performed by a surgeon in a facility setting for a patient with an existing vagus nerve stimulation system, often used to treat epilepsy. Removal may involve dissection of the lead from the nerve and removal of the generator from its implant pocket.
Report the code when both the electrode array and pulse generator are removed; removal is distinct from revising or replacing the array. The operative report should identify the vagus nerve system and document the components taken out. 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 one session, the highest-valued procedure is paid in full and other procedures at 50%. For bilateral procedures, modifier 50 is paid at 150%. Assistant-at-surgery, co-surgeon, and team-surgery payment requires supporting documentation as applicable.
