Using an open incision or a percutaneous (small incision in the skin) approach, the provider places a balloon–tipped catheter into the lumen (interior) of an artery. He expands the balloon as many times and at as many points as necessary within the same artery to open up the artery and improve blood circulation. The procedure includes all imaging guidance and diagnostic imaging necessary to carry out the angioplasty and all radiological supervision and interpretation (RS&I); do not report this code for this procedure on the dialysis circuit or the lower extremity, intracranial, coronary, or pulmonary arteries.
