CPT® Code 35471

The procedure described by CPT® Code 35471 refers to a percutaneous transluminal balloon angioplasty specifically targeting the renal or visceral arteries. This minimally invasive technique is utilized to treat arterial blockages that can impede blood flow to vital organs. During the procedure, the physician accesses the affected artery, typically through the femoral artery, which is located in the groin area. The process begins with the preparation of the skin and puncturing of the artery using a needle to gain access. A sheath is then inserted to facilitate the introduction of other instruments. A guidewire is carefully navigated through the sheath and into the occluded artery, allowing for the advancement of a catheter equipped with a balloon tip. Once positioned at the site of the blockage, the balloon is inflated, exerting pressure that compresses the plaque against the arterial wall, thereby widening the vessel and restoring blood flow. This inflation may be repeated multiple times to achieve optimal results. Following the angioplasty, the catheter is exchanged for a guidewire, and an angiography catheter is introduced to assess the success of the procedure. Contrast material is injected to visualize the artery, confirming its patency through imaging. After the angiography, the catheter is removed, and pressure is applied to the puncture site to prevent bleeding, followed by the application of a pressure dressing to ensure proper healing.
