Vascular surgery

About 35601: Common-to-internal carotid bypass graft

Open bypass from the common carotid artery to the same-side internal carotid artery restores flow around a segment requiring vascular reconstruction.

This open arterial reconstruction creates a graft route from the common carotid artery to the internal carotid artery on the same side. It restores blood flow past a segment that cannot carry blood adequately or must be bypassed during vascular reconstruction. Vascular surgeons typically perform the operation in an operating room. The operative report should identify the inflow artery, outflow artery, graft, and completed route.

Report 35601 when the documented bypass runs from the common carotid to the ipsilateral internal carotid; select the code by the anatomic endpoints, not the diagnosis alone. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. In a same-session multiple-procedure claim, the highest-valued procedure is paid in full and other procedures at 50%. Bilateral performance with modifier 50 is paid at 150%. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
