What 35666 covers

A vascular surgeon creates a bypass from a femoral artery to an anterior tibial, posterior tibial, or peroneal artery using a graft other than vein. This distal revascularization is used to route blood around obstructive disease in the leg, commonly in limb-salvage surgery for severe peripheral arterial disease. The operation is generally performed in a hospital operating room; the operative report identifies the bypass origin, distal target, and graft material.

Choose this code when the documented inflow is femoral, the outflow is one of the specified tibial or peroneal arteries, and the conduit is not vein. The code has a 90-day global period, including 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 are subject to a 50% reduction. Bilateral reporting with modifier 50 is paid at 150%. An assistant at surgery may be paid; co-surgeons are paid only with 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.

35666 billing questions

When should 35666 be chosen instead of 35566?

Use 35666 for the specified femoral-to-tibial or peroneal bypass when the graft is other than vein. Use 35566 for the same route when a vein graft is used.

Which details should the operative report support?

Document the femoral inflow artery, the anterior tibial, posterior tibial, or peroneal outflow target, and the graft material. These details distinguish 35666 from bypass codes with another origin, destination, or conduit.

How is bilateral surgery reported?

For bilateral procedures, report modifier 50; CMS pays the procedure at 150%.

How does the multiple-procedure reduction affect 35666?

When other procedures are performed in the same session, the highest-valued procedure is paid in full and the other procedures are paid at 50%.

Can an assistant or co-surgeon be reported?

An assistant at surgery may be paid. Co-surgeons are paid only when supporting documentation is provided; team surgery is not permitted.

What postoperative care is included?

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

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.
