About 35510: Carotid-to-brachial arterial bypass

Reports open bypass from a carotid artery to a brachial artery to restore blood flow to an arm when native arterial circulation is inadequate.

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.

Arterial bypass

Axillary to brachial

No office rate

35522 describes an axillary-to-brachial bypass. The distal brachial endpoint is shared, but the inflow vessel differs from 35510.

35510 billing questions

How is 35510 distinguished from other upper-extremity bypass codes?

Use 35510 when the bypass runs from a carotid artery to a brachial artery. Select the code for the actual inflow and outflow vessels when either endpoint differs.

What operative details support reporting 35510?

Document the clinical indication, side, carotid inflow, brachial outflow, graft route and conduit, and the completed anastomoses.

Does the 90-day global period include postoperative care?

Yes. It includes the day-before preoperative visit and 90 days of related postoperative care.

How does Medicare handle bilateral reporting and multiple procedures?

Bilateral reporting with modifier 50 is paid at 150%. For multiple procedures in one session, the highest-valued procedure is paid in full and the others at 50%.

Can an assistant or co-surgeon be reported?

An assistant at surgery may be paid. Co-surgeon payment requires supporting documentation; team surgery is not permitted.

Is vein harvest included in 35510?

If a separate vein-harvest service is performed, evaluate 35500 and document the harvest. Do not assume separate payment without checking the applicable coding edits.
