Ask Dr. Z

The patient came in for AV graft(36830) along with basilic vein graft after a diminished distal brachial pulse. Would there be a separate code for the vein patch angioplasty?

"Following initial construction of a brachial–axillary left upper arm AV graft, there was a complete loss of left radial pulse and Doppler signal, as well as a diminished pulse in the distal brachial artery. Due to significant concern for ischemic steal, I elected to revise the graft with more proximal looped inflow. The arterial anastomosis was taken down and the brachial artery was repaired with a patch of neighboring basilic vein. New inflow was constructed onto the axillary artery adjacent to our venous outflow anastomosis and a second graft segment was tunneled in the more medial upper arm. The 2 grafts were anastomosed to 1 another, creating a looped upper arm axillary–axillary AV graft. Upon completion, there was a palpable thrill in the graft, an ongoing faintly palpable radial pulse, and a multiphasic radial Doppler signal."
