What 35510 covers
Code 35510 describes an open operation that routes blood from a carotid artery to a brachial artery through a bypass graft. Vascular surgeons typically perform it in a hospital operating room for selected patients with serious arm ischemia when the usual proximal arterial inflow is unsuitable. The operative report should identify the inflow and outflow arteries, side, graft route and conduit, and the reason for the reconstruction.
Select this code when the bypass connects the carotid and brachial arteries; a bypass between different named vessels belongs to the code matching those sites. The 90-day global period includes 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 at 50%. Bilateral reporting with modifier 50 is paid at 150%. An assistant at surgery may be paid; co-surgeons require supporting documentation, and team surgery is not permitted.

How to choose
- 35512Arterial bypass

- 35522Arterial bypass
- 35522 describes an axillary-to-brachial bypass. The distal brachial endpoint is shared, but the inflow vessel differs from 35510.
- 35501Carotid bypass
- 35501 describes a carotid bypass with a different distal target. Use 35510 only when the brachial artery is the outflow vessel.
