Vascular surgery

About 35571: Popliteal-to-distal vein bypass

Reports a vein-graft bypass from the popliteal artery to a tibial, peroneal, or other distal artery to restore lower-extremity blood flow.

A vascular surgeon uses a vein graft to route blood from the popliteal artery around an obstructed segment to a tibial, peroneal, or other distal artery. The operation is used for lower-extremity arterial occlusive disease when revascularization to a distal target is needed, such as in a patient with limb-threatening ischemia. It is typically performed in a hospital operating room.

Report the bypass when the operative record supports a popliteal inflow artery, a distal arterial outflow target, and a vein-graft technique. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. Bilateral reporting 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.

35571 billing questions

How is this code distinguished from 35566?

This code describes a bypass originating at the popliteal artery. Code 35566 describes a bypass originating at the femoral artery and extending to a tibial, peroneal, or related distal target.

When is 35587 a better fit?

Use 35587 when the procedure is an in-situ vein bypass from the popliteal artery to a tibial, peroneal, or other distal vessel. This code describes a vein-graft bypass that is not reported as an in-situ bypass.

What operative details support reporting this code?

The operative report should identify the popliteal inflow, the distal outflow artery, and the vein-graft bypass technique. It should also describe the bypass performed and the treated arterial disease.

How is bilateral surgery handled?

CMS lists bilateral reporting with modifier 50 at 150%. The global period is 90 days, including the day-before preoperative visit and related postoperative care.

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.
