CPT® Code 35475

The procedure described by CPT® Code 35475 refers to transluminal balloon angioplasty performed percutaneously on the brachiocephalic trunk or its branches, with each vessel treated being billed separately. This minimally invasive technique is utilized to open narrowed or blocked arteries, specifically targeting the brachiocephalic artery, which is a major vessel supplying blood to the right arm and head. The process begins with the preparation of the skin over the access artery, typically the brachiocephalic artery, followed by puncturing the artery with a needle to insert a sheath. A guidewire is then navigated through the access point into the occluded area of the artery. A catheter equipped with a balloon tip is advanced over this guidewire to the site of the blockage. Once positioned, the balloon is inflated, compressing the plaque against the arterial wall to restore blood flow. This inflation may be repeated multiple times to achieve optimal results. After the angioplasty, the catheter is exchanged for a guidewire, and an angiography catheter is introduced to assess the success of the procedure through completion angiography, ensuring the artery is patent. Finally, the angiography catheter is removed, and pressure is applied to the puncture site to prevent bleeding, followed by the application of a pressure dressing. This comprehensive approach allows for effective treatment of arterial blockages in the brachiocephalic trunk or branches.
