What 35570 covers

This operation uses a vein conduit to bypass obstructive disease between a tibial artery and another tibial artery or the peroneal artery. A vascular surgeon typically performs it in an operating room for severe lower-extremity ischemia when revascularization must reach below the knee. The defining anatomy is tibial-level inflow and a tibial or peroneal outflow target, rather than femoral or popliteal inflow. The conduit is vein, commonly the patient’s own vein.

Select the code from the documented bypass origin, distal target, and conduit. The operative report should identify the arteries joined, the vein conduit, laterality, and bypass performed. CMS assigns 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 others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery services may be paid; co-surgeons require supporting documentation, and team surgery is not permitted.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

How to choose

35566Leg bypass
Both describe vein bypasses to tibial or peroneal arteries. Choose 35566 when the bypass begins at the femoral artery; choose 35570 when it begins at a tibial artery.
35571Arterial bypass
Both use vein for a distal bypass, but 35571 begins at the popliteal artery. Code 35570 requires tibial inflow.
35585Vein bypass
Code 35585 describes an in-situ vein bypass from the femoral artery to a tibial or peroneal target. Code 35570 describes a tibial-origin bypass.

35570 billing questions

How is 35570 distinguished from 35566 or 35571?

Use the bypass origin and target arteries. This code is for tibial-to-tibial or tibial-to-peroneal bypass; 35566 has femoral inflow, while 35571 has popliteal inflow.

Does this code describe an in-situ vein bypass?

No. Code 35570 describes a tibial-origin bypass using a vein conduit. Code 35585 describes an in-situ vein bypass from the femoral artery to a tibial or peroneal artery.

Can vein harvest be reported separately?

When an upper-extremity vein is harvested for a lower-extremity bypass, code 35500 may be reported as an add-on when its requirements are met. Document the harvest site and work performed.

What postoperative care is included?

The 90-day global period includes the day-before preoperative visit and related postoperative care during the 90 days after surgery.

How does CMS handle bilateral reporting and multiple procedures?

Bilateral reporting with modifier 50 is paid at 150%. In a same-session multiple-procedure setting, the highest-valued procedure is paid in full and other procedures at 50%.

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.
