Official Description

Transcatheter placement of an intravascular stent(s) (except coronary, carotid, vertebral, iliac, and lower extremity arteries), percutaneous; each additional vessel (List separately in addition to code for primary procedure)

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 37206 refers to the transcatheter placement of an intravascular stent in an additional vessel during a percutaneous procedure. This code is specifically designated for use when a stent is placed in a vessel that is not classified as coronary, carotid, vertebral, iliac, or lower extremity arteries. An intravascular stent is a small, mesh-like tube that is inserted into a narrowed or blocked blood vessel to help maintain its patency and improve blood flow. The procedure involves the use of a catheter, which is a thin, flexible tube that is inserted into the vascular system to reach the site of the blockage or narrowing. Once the catheter is positioned correctly, the stent is deployed through the catheter and expanded to fit the vessel wall, thereby providing structural support and preventing re-narrowing. This code is utilized in conjunction with a primary procedure code that describes the initial stenting operation, and it is important to note that this is an add-on code, meaning it is billed in addition to the primary procedure code for the first vessel treated. Fluoroscopy or ultrasound may be employed during the procedure to guide the placement of the stent, ensuring accurate positioning and deployment. The use of this code indicates that multiple vessels may be treated in a single session, enhancing the overall effectiveness of the intervention while adhering to the specified exclusions for certain vascular territories.

1. Indications

The CPT® Code 37206 is indicated for use in cases where there is a need for the placement of an intravascular stent in an additional vessel during a percutaneous procedure. The following conditions may warrant the use of this code:

  • Stenosis - A narrowing of the blood vessel that restricts blood flow.
  • Occlusion - A blockage in the blood vessel that impedes circulation.
  • Peripheral artery disease - A condition that affects blood flow to the limbs, necessitating intervention in vessels outside the coronary, carotid, vertebral, iliac, or lower extremity arteries.

2. Procedure

The procedure associated with CPT® Code 37206 involves several key steps that ensure the successful placement of an intravascular stent in an additional vessel. Each step is critical to achieving the desired outcome of restoring blood flow.

  • Step 1: Catheter Insertion - The procedure begins with the insertion of a catheter into the vascular system. This is typically done through a small incision in the skin, allowing access to a major blood vessel. The catheter is carefully advanced through the vascular system to reach the site of the stenosis or occlusion.
  • Step 2: Positioning the Catheter - Once the catheter is in place, it is navigated to the specific location within the vessel that requires stenting. This may involve the use of imaging techniques such as fluoroscopy or ultrasound to ensure accurate positioning and to visualize the anatomy of the blood vessel.
  • Step 3: Stent Deployment - After the catheter is correctly positioned, the stent is introduced through the catheter. The stent is typically mounted on a balloon catheter, which is inflated to expand the stent against the vessel wall. This action secures the stent in place, providing structural support to the vessel and improving blood flow.
  • Step 4: Catheter Removal - Following the successful deployment of the stent, the catheter is carefully withdrawn from the vessel. The site of insertion may be closed with a bandage or other closure device, depending on the specific technique used.

3. Post-Procedure

After the procedure associated with CPT® Code 37206, patients may require monitoring for any potential complications, such as bleeding or infection at the catheter insertion site. Recovery typically involves a short observation period in a healthcare facility, where vital signs are monitored, and the patient is assessed for any immediate post-procedural issues. Patients may be advised to avoid strenuous activities for a specified period to allow for proper healing. Follow-up appointments may be scheduled to evaluate the effectiveness of the stent placement and to ensure that blood flow has been adequately restored. Additionally, patients may be prescribed medications to prevent blood clots and to manage any underlying conditions that contributed to the need for stenting.
