Ask Dr. Z

Provider performs an above-the-knee to below-the-knee bypass with reverse saphenous vein graft. Would it be appropriate to report code 35571 since this bypass graft is from the popliteal artery, above the knee, to just above the AT artery takeoff?

"An arteriotomy was made in the distal popliteal artery just above the anterior tibial artery takeoff. The vein graft was then spatulated, and the distal anastomosis was created with a 6-0 Prolene suture, end-to-side. Prior to completion, all arteries were allowed to backbleed. The lumen was flushed with heparinized saline. The vein graft was flushed, and the anastomosis was hemostatic. The popliteal artery above the knee was then clamped. An arteriotomy was made and extended with Potts scissors. The vein graft was cut to appropriate size and spatulated. An end-to-side anastomosis was created with a 6-0 Prolene suture. Prior to completion, all arteries were allowed to backbleed and flush. The lumen was flushed with heparinized saline solution. I then completed the anastomosis and restored flow to the foot."
