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

What 35646 covers

A vascular surgeon uses a conduit other than vein, typically a synthetic graft, to route blood from the aorta to the femoral artery in each groin. This operation is commonly performed in an operating room for extensive aortoiliac occlusive disease causing significant lower-extremity ischemia. The graft’s two limbs provide anatomic outflow to both sides; the operative report should identify the aortic inflow, both femoral targets, and conduit material.

Report this code when the bypass runs from the aorta to both femoral arteries using a non-vein conduit. Documentation should establish the indication, graft route and material, and the two distal anastomoses. CMS assigns a 90-day global period, including 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% reduction. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
