Right external into common iliac stent placement
provider performed stent placement in the external iliac artery. He covered that stent using a larger stent with a balloon to force dilation. There was significant dissection near the second deployed stent, so he deployed another stent in the internal iliac artery. After the stenting was done he advanced a mulltipurpose catheter into the common iliac artery and performed an angiograph to make sure there was no flow limitations. All of this was does percutaneously. I believe 37205 and 37206 are appropriate for the stent placements, but what do I use for the angiograph.
