CPT® Code 35472

The CPT® Code 35472 refers to a specific medical procedure known as percutaneous transluminal balloon angioplasty of the aorta. This procedure is performed to treat occlusions or blockages in the aorta, which is the main artery supplying blood to the body. During the procedure, a physician accesses the aorta through the skin, typically using one of the femoral arteries located in the groin area. The process begins with the preparation of the skin and puncturing of the artery with a needle to gain access. A sheath is then inserted into the artery to facilitate the introduction of other instruments. A guidewire is advanced through the sheath into the aorta, allowing for the placement of a catheter equipped with a balloon tip. This balloon is positioned at the site of the blockage and inflated to compress the plaque against the arterial wall, thereby widening the artery and restoring blood flow. The balloon may be inflated multiple times to achieve optimal results. Following the angioplasty, an angiography catheter is used to inject contrast material and perform imaging to confirm that the artery is open and functioning properly. The procedure concludes with the application of pressure to the puncture site to prevent bleeding, followed by the placement of a pressure dressing. This detailed description highlights the technical aspects of the procedure while ensuring clarity for medical coders and healthcare professionals involved in the coding and billing process.
