Ask Dr. Z

"With a NaviCross catheter and a stiff angled Glidewire, access was ultimately gained to the inferior vena cava, confirmed by injection in the inferior vena cava. The wire was then exchanged through the catheter for a Storq wire. The catheter was then withdrawn. A 7 mm percutaneous transluminal balloon angioplasty was performed to the level of the inferior vena cava, all the way to the level of the femoral vein, through the external iliac vein and common iliac veins via inflations to 10 atmospheres at 30 seconds x4. Venous balloon angioplasty was performed in order to expose more fibrin receptors in this chronic DVT setting for improved thrombolysis." I want to verify that the angioplasty cannot be coded. It was not done specifically for maceration, which is not allowed, but the reason for it does not seem justified for coding either.
