"5 French angled glide catheter was advanced over this wire into the distal radial artery. Fistulogram with radiological supervision and interpretation was then performed. This revealed near occlusive stenosis at the arteriovenous anastomosis and proximal outflow. 4 mm x 40 mm Mustang balloon was brought to the arteriovenous anastomosis, and balloon angioplasty was performed of the segment. The 4 mm x 40 mm balloon was also used to perform balloon angioplasty of the proximal outflow. Fistulogram was performed, which revealed significant improvement of the severe arteriovenous anastomotic stenosis. The 6 mm x 40 mm balloon was then brought into the proximal venous outflow, and balloon angioplasty was performed." 

Would you report codes 36215, 75710, and 36902 since the catheter was advanced to the distal radial artery? I reported code 36902 only. Can you give more explanation to what is considered arterial inflow in the dialysis circuit? Isn't this beyond perianastomotic segment for 36215 and 75710 to be used?
