Ask Dr. Z

Received a denial stating that code 35351 was documented in the record. Here is what was documented: "9 x 40 balloon angioplasty balloon was advanced into the common iliac artery and used to provide control. Distal external iliac artery was clamped distally. Longitudinal arteriotomy was made with a 12 blade and extended proximally distally with the Potts until adequate endpoints have been achieved. Thin endarterectomy plane was created and plaque was passed off. 5-0 Prolene and bovine pericardial patch was used to create left external iliac patch angioplasty. There was excellent distal external iliac pulse at this point after balloon control was withdrawn."
