Ask Dr. Z

"Thirty minutes prior to the procedure, I placed 2 mg of tissue plasminogen activator into the graft. This was allowed to dell. We then accessed the graft initially near the arterial limb, but I could not be sure if I was in. Therefore, I went further distally and accessed antegrade towards the venous limb. We were able to successfully place a 6 French sheath. I was able to aspirate thrombus. Imaging revealed a high grade stenosis at the saphenofemoral junction and the previously stented area. We then treated the outflow with a 7 x 40 mm balloon. An arterial sheath was placed in the opposite direction near the same area, and a wire was able to be advanced up into the left external iliac artery through the common femoral artery. We then treated the first segment of the arterial limb of the graft with a 7 x 40 mm Dorado balloon. Finding stenosis at saphenofemeral junction, proximal portion of venous outflow and first segment of the AV graft near the arterial anastomosis." I reported this with codes 36870, 372220, 35476, 75978, 36147, and 36148.  Am I correct?
