Official Description

Intravascular ultrasound (non-coronary vessel) during diagnostic evaluation and/or therapeutic intervention; initial vessel (List separately in addition to code for primary procedure)

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

Intravascular ultrasound (IVUS) is a specialized imaging technique used to visualize the interior of blood vessels, specifically non-coronary vessels, during diagnostic evaluations and therapeutic interventions. This procedure provides a detailed cross-sectional view of the vessel, allowing healthcare professionals to assess the various layers of the blood vessel wall, which include the outer covering known as the adventitia, the middle layer referred to as the media, the inner endothelial layer called the intima, and the lumen, which is the open channel through which blood flows. The use of IVUS is critical in enhancing the understanding of vascular conditions and guiding treatment decisions. During the procedure, a miniaturized transducer is mounted on an IVUS catheter, which is advanced over a guidewire to the specific site that requires evaluation. The ultrasound images captured during this process are then reviewed by the physician, who generates a comprehensive written report detailing the findings from the IVUS examination. It is important to note that CPT® Code 37250 is designated for the initial vessel evaluated using IVUS, while CPT® Code 37251 is used for each additional vessel assessed during the same session.

1. Indications

Intravascular ultrasound (IVUS) is indicated for use during diagnostic evaluations and therapeutic interventions involving non-coronary vessels. The procedure is typically performed to assess various vascular conditions, including but not limited to:

  • Assessment of Vascular Lesions Evaluation of the presence and characteristics of lesions within the blood vessel.
  • Guidance for Interventions Providing real-time imaging to assist in guiding therapeutic interventions such as stent placement or balloon angioplasty.
  • Evaluation of Vascular Anatomy Detailed visualization of the vascular anatomy to aid in the diagnosis and treatment planning for vascular diseases.

2. Procedure

The procedure for intravascular ultrasound (IVUS) involves several key steps that ensure accurate imaging and assessment of the non-coronary vessel:

  • Step 1: Preparation The patient is prepared for the procedure, which may include sedation and local anesthesia, depending on the specific clinical scenario and the physician's preference.
  • Step 2: Catheter Insertion A catheter is inserted into the vascular system, typically through a peripheral access point. This catheter is designed to accommodate the IVUS transducer.
  • Step 3: Guidewire Advancement A guidewire is advanced through the catheter to the target site within the non-coronary vessel. This guidewire serves as a pathway for the IVUS catheter.
  • Step 4: IVUS Catheter Advancement The IVUS catheter, equipped with a miniaturized transducer, is then advanced over the guidewire to the specific area of interest within the vessel.
  • Step 5: Image Acquisition Once positioned, the transducer emits ultrasound waves, which penetrate the vessel wall and reflect back, creating detailed images of the vessel's internal structure. These images are captured and displayed in real-time.
  • Step 6: Image Review The physician reviews the ultrasound images obtained during the procedure, assessing the vascular anatomy and any abnormalities present.
  • Step 7: Reporting A comprehensive written report is generated by the physician, summarizing the findings from the IVUS examination, which may be used for further diagnostic or therapeutic decision-making.

3. Post-Procedure

After the completion of the intravascular ultrasound procedure, the patient is monitored for any immediate complications related to the catheter insertion or the procedure itself. Depending on the patient's condition and the extent of the procedure, recovery may vary. Patients are typically advised to rest and may be observed for a short period to ensure stability. Follow-up care may include reviewing the IVUS report with the healthcare team to discuss findings and potential next steps in management or treatment based on the results of the ultrasound evaluation.
