Ask Dr. Z

I need help coding this report. The procedures were left heart catheterization, selective cornonary, saphenous vein and IM angiography, ventriculography, RAO view, aortography, AP view, right iliac angiogram, and primary stenting of vein graft to RCA with use of spider. Closure of access site using Mynx grip. Here is the part of the note that I don't know how to code: "Aortography was performed in the AP view, as patient was complaining of discomfort in his right leg. This shows significant stenosis of 60-70% in the right common iliac, which with the placement of the catheter was obstructing flow. Following this, selective right iliac angiogram was performed, and this iliac appeared to be diffusely diseased with 60-70% narrowing, but I felt I could get the procedure done and bring him back for elective intervention of his iliac vessel." I am new to cardiac coding, so I'm feeling very lost. The patient has Medicare.
