Ask Dr. Z

Left upper extremity fistulogram. The stenosis in the graft venous anastomosis was crossed with the wire. Angioplasty of the stenosis in the graft venous anastomosis was performed using 8x40 mm Balloon; then sheath was redirected towards the arterial inflow. Balloon angioplasty of the arterial anastomosis with a 6x40 mm balloon. (Same Access) do I bill both 36902 and 36907?

What if the physician uses a second access to access arterial anastomosis, any other access code to bill for second access?
