Ask Dr. Z

With the new 2010 AV fistula codes I am not sure how to code a cath placement. Fistula was accessed with a needle, contrast imaging done (36147). Tapered narrowing approaching the arterial anastomosis. The arterial anastomosis itself is moderately narrowed. The entire juxtaanastomotic segment was irregular in contour with two discrete moderate foci of stenosis. Balloon cath was advanced over the wire. Angioplastied the inflow segment down to the radial artery in an overlapping fashion (35475 & 75962). Can I also charge for catheter placement in the radial artery 36140? Thanks for your help.
