"Transection of radial artery due to traumatic glass window injury. Decision made to perform an interposition bypass. A small incision was made in the proximal forearm; branch of the cephalic vein dissected free and harvested. The radial artery was spatulated, the cephalic vein was spatulated, and end-to-end anastomosis performed using 6-0 Prolene. The clamp was then moved onto the bypass. The distal radial artery was interrogated with a 2 Fogarty to ensure no thrombus, spatulated, and an end-to-end anastomosis was performed from the cephalic vein to the radial artery with 6-0 Prolene. Clamps released, suture was tied down, and hemostasis was achieved. A palpable radial pulse was present, and a Doppler signal was present in the superficial and deep palmar arches."  There is no code for radial-radial BPG. Would you use code 35523?
