What 35671 covers

A vascular surgeon uses this procedure to route blood around an obstructed segment of the lower-extremity arterial circulation, connecting the popliteal artery to a tibial or peroneal artery with a conduit other than vein, often a prosthetic graft. It is used for limb revascularization when disease affects the arterial route to the lower leg or foot and the selected bypass begins at the popliteal artery and reaches one of these distal vessels. The operation is generally performed in a hospital operating room.

Select the code based on the bypass endpoints and conduit documented in the operative report. Documentation should identify the popliteal inflow site, the tibial or peroneal outflow vessel, and use of a non-vein conduit; an autogenous vein bypass is coded differently. The service has a 90-day global period, including the day-before preoperative visit and related postoperative care during that period. 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%. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

35671 billing questions

How does this differ from 35571?

Both codes describe a popliteal-origin bypass to a tibial or peroneal artery. Use 35671 for a conduit other than vein and 35571 for a vein conduit.

When would 35666 be used instead?

35666 describes a non-vein bypass beginning at the femoral artery and reaching an anterior tibial, posterior tibial, or peroneal artery. The documented bypass origin distinguishes it from 35671.

What operative details support 35671?

The operative report should identify the popliteal artery as the bypass inflow, the tibial or peroneal artery as the outflow, and the use of a non-vein conduit.

How is bilateral reporting handled?

When the procedure is performed bilaterally and reported with modifier 50, CMS pays it at 150%.

Can an assistant or co-surgeon be reported?

Assistant-at-surgery payment may be made. Co-surgeon payment requires supporting documentation; team surgery is not permitted.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
