What 64655 covers
This surgery addresses a lead in an implanted baroreflex activation therapy (BAT) system, which stimulates baroreceptors near the carotid sinus. The surgeon revises the existing lead or replaces it; this is lead work, not pulse-generator revision or removal. The system is used for baroreflex activation therapy, including treatment of hypertension. The procedure is performed in an operating room by a surgeon experienced with the implanted system and its lead placement.
Report 64655 when the operative work is revision or replacement of the BAT system lead. The operative report should identify the system component treated, describe the lead work performed, and support the medical reason for the procedure. 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 others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery, co-surgeon, and team-surgery payment each require supporting documentation; assistant payment also requires medical necessity documentation.
