CPT® Code 35450

Deleted

The procedure described by CPT® Code 35450 refers to an open transluminal balloon angioplasty performed on a renal or other visceral artery. This medical intervention is aimed at treating blockages or narrowing within these arteries, which can impede blood flow and lead to various health complications. During the procedure, the physician makes an incision in the skin over the access artery to expose it. A sheath is then inserted into the artery, allowing for the introduction of a guidewire. This guidewire is carefully navigated through the artery to the site of the blockage. A catheter equipped with a balloon tip is advanced over the guidewire to the occluded area. Once in position, the balloon is inflated, which compresses the plaque against the arterial wall, thereby widening the artery and restoring blood flow. The inflation of the balloon may be repeated multiple times to achieve optimal results. Following the angioplasty, an angiography catheter is used to inject contrast material and perform a completion angiography, ensuring that the artery is open and functioning properly. Finally, the access artery is repaired, and the skin incision is closed, completing the procedure.
