Official Description

Transluminal balloon angioplasty, percutaneous; aortic

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

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.

1. Indications

The procedure described by CPT® Code 35472 is indicated for patients experiencing occlusions or significant blockages in the aorta. These conditions may lead to reduced blood flow and can result in various complications. The following are specific indications for performing this procedure:

  • Aortic Occlusion The presence of a blockage in the aorta that impedes blood flow, potentially leading to ischemia or other serious cardiovascular issues.
  • Peripheral Artery Disease A condition characterized by narrowed arteries, which can affect blood circulation to the limbs and organs, necessitating intervention to restore adequate blood flow.
  • Symptoms of Ischemia Patients may present with symptoms such as claudication, pain, or discomfort in the limbs due to insufficient blood supply, prompting the need for angioplasty.

2. Procedure

The procedure for CPT® Code 35472 involves several critical steps to ensure successful angioplasty of the aorta. Each step is essential for achieving the desired outcome of restoring blood flow through the affected artery:

  • Step 1: Preparation and Access The procedure begins with the preparation of the skin over the access artery, typically one of the femoral arteries. The area is cleaned and sterilized to minimize the risk of infection. A needle is then used to puncture the artery, allowing for access to the vascular system.
  • Step 2: Sheath Insertion Following the arterial puncture, a sheath is inserted into the artery. This sheath serves as a conduit for the introduction of other instruments necessary for the procedure, ensuring a stable access point.
  • Step 3: Guidewire Placement A guidewire is then inserted through the sheath and advanced into the aorta. This guidewire is crucial as it provides a pathway for the subsequent catheter and balloon to reach the site of the occlusion.
  • Step 4: Catheter Advancement A catheter with a balloon tip is advanced over the guidewire to the location of the blockage in the aorta. This step requires careful navigation to ensure that the catheter reaches the precise area needing treatment.
  • Step 5: Balloon Inflation Once the catheter is in place, the balloon at its tip is inflated. This inflation compresses the plaque against the arterial wall, widening the artery and restoring blood flow. The balloon may be inflated multiple times to achieve the best possible results.
  • Step 6: Angiography After the balloon angioplasty, the angioplasty catheter is exchanged for a guidewire, and an angiography catheter is advanced over the guidewire. The guidewire is then withdrawn, and contrast material is injected through the angiography catheter. This imaging step is performed to confirm that the artery is patent and that blood flow has been successfully restored.
  • Step 7: Closure Following the angiography, the angiography catheter is withdrawn. Pressure is applied to the arterial puncture site to control any bleeding, and a pressure dressing is applied to secure the site and promote healing.

3. Post-Procedure

After the completion of the angioplasty procedure, several post-procedure care steps are essential to ensure patient safety and recovery. The physician will monitor the patient for any signs of complications, such as bleeding or infection at the puncture site. Patients are typically advised to rest and may be instructed to limit physical activity for a specified period to allow for proper healing. Follow-up appointments may be scheduled to assess the success of the procedure and to monitor the patient's recovery. Additionally, patients may receive instructions regarding medication management, including antiplatelet therapy, to prevent future occlusions. Overall, careful post-procedure management is crucial for optimizing patient outcomes following aortic balloon angioplasty.
