Official Description

Transluminal balloon angioplasty, central dialysis segment, performed through dialysis circuit, including all imaging and radiological supervision and interpretation required to perform the angioplasty (List separately in addition to code for primary procedure)

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

Transluminal balloon angioplasty, as described by CPT® Code 36907, is a medical procedure aimed at restoring adequate blood flow through a narrowed or obstructed central venous dialysis segment. This segment may include critical veins such as the axillary vein, subclavian vein, innominate vein, or vena cava. The procedure is particularly relevant for patients experiencing hemodialysis-related central venous occlusive disease (CVOD), which can manifest through symptoms such as elevated urea recirculation, increased venous dialysis pressure, and arm edema. The access point for this procedure is typically through an arteriovenous (AV) graft or fistula, which is punctured with a needle to facilitate the introduction of a guidewire. Following this, a vascular sheath is placed, allowing for the insertion of a catheter that enables angiography to visualize the affected central venous segments. If stenosis, or narrowing, is detected, a balloon-tipped catheter is utilized to perform the angioplasty. This involves inflating the balloon with a radiopaque contrast agent under fluoroscopic guidance to ensure proper visualization and effectiveness. After the procedure, if residual stenosis is identified, a stent may be deployed to maintain vessel patency. The entire process includes necessary imaging and radiological supervision, ensuring that the procedure is conducted safely and effectively.

1. Indications

Transluminal balloon angioplasty (CPT® Code 36907) is indicated for patients presenting with symptoms associated with hemodialysis-related central venous occlusive disease (CVOD). The specific indications for this procedure include:

  • Elevated Urea Recirculation - This condition indicates that the blood is not being adequately filtered during dialysis, leading to increased levels of urea in the bloodstream.
  • Elevated Venous Dialysis Pressure - High venous pressure during dialysis can suggest obstruction in the central venous system, necessitating intervention to restore normal flow.
  • Arm Edema - Swelling in the arm can occur due to impaired venous return, often a result of central venous stenosis, which may require angioplasty to alleviate.

2. Procedure

The procedure for transluminal balloon angioplasty involves several critical steps to ensure successful restoration of blood flow through the central venous dialysis segment. The steps are as follows:

  • Accessing the AV Graft/Fistula - The procedure begins with the puncture of the AV graft or fistula using a needle. This access point is essential for introducing the necessary instruments for the angioplasty.
  • Guidewire Insertion - A guidewire is threaded through the needle into the vascular system, providing a pathway for subsequent devices.
  • Vascular Sheath Placement - The needle is exchanged for a vascular sheath, which allows for the safe passage of a catheter into the central venous segment.
  • Angiography - A catheter is placed over the guidewire, and angiography is performed to visualize the central venous segments. This imaging step is crucial for identifying any stenosis.
  • Balloon Angioplasty - Once stenosis is confirmed, a balloon-tipped catheter is inserted over the guidewire and positioned at the site of narrowing. The balloon is then inflated with dilute radiopaque contrast under fluoroscopic guidance to expand the vessel.
  • Balloon Deflation and Catheter Removal - After the prescribed inflation time, the balloon is deflated, and the catheter is removed, allowing for assessment of the vessel.
  • Repeat Angiography - A vascular catheter with a working channel is threaded over the guidewire, and angiography is repeated to evaluate for any resistant or residual stenosis.
  • Stent Placement (if necessary) - If residual stenosis is detected, a fine mesh or wire stent is delivered to the stenotic area through the working channel of the vascular catheter. The stent expands to apply pressure on the vessel walls, keeping the segment open.
  • Final Steps - After stent placement, the catheter is removed, and a purse string suture may be placed to control any bleeding before the vascular sheath is finally removed.

3. Post-Procedure

Post-procedure care following transluminal balloon angioplasty includes monitoring for any complications such as bleeding or infection at the access site. Patients may also require follow-up imaging to ensure the effectiveness of the angioplasty and stent placement. It is essential to assess the patency of the central venous segment and monitor for any recurrence of symptoms associated with CVOD. Additionally, healthcare providers should provide instructions regarding activity restrictions and signs of complications that patients should report.
