Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 35556 covers

A vascular surgeon uses a vein conduit to route blood from the femoral artery to the popliteal artery, bypassing an obstructed segment. The operation is commonly performed in a hospital operating room for lower-extremity arterial occlusive disease when revascularization is needed. A harvested saphenous vein is a familiar conduit example. This code distinguishes a vein-graft bypass from a bypass using a non-vein graft and from an in-situ vein bypass.

Select the code based on the documented conduit, bypass endpoints, and operative technique. The report should identify the femoral inflow, popliteal outflow, vein graft, and bypass performed. CMS assigns major surgery a 90-day global period, including the day-before preoperative visit and related postoperative care through day 90. For multiple procedures in one 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 payment may be allowed; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
