Official Description

Common carotid intima-media thickness (IMT) study for evaluation of atherosclerotic burden or coronary heart disease risk factor assessment

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 0126T refers to a non-invasive diagnostic procedure known as the common carotid intima-media thickness (IMT) study. This study is specifically designed to image the common carotid artery, which is a major blood vessel that supplies blood to the brain, neck, and face. The primary purpose of this procedure is to evaluate the atherosclerotic burden, which refers to the accumulation of fatty deposits, known as plaques, within the arterial walls. Additionally, it serves as a tool for assessing risk factors associated with coronary heart disease, a condition characterized by the narrowing of the coronary arteries due to plaque buildup. During the IMT study, ultrasound technology is utilized to capture detailed images of the intima-media thickness of the common carotid artery. These images are then analyzed using specialized computer software, which helps in documenting the presence and extent of any atherosclerotic plaque present in the vessel. An increase in the thickness of the intima-media is clinically significant, as it may indicate generalized atherosclerosis, which can include conditions such as coronary artery disease. This procedure is crucial for early detection and risk stratification in patients who may be at risk for cardiovascular events.

1. Indications

The common carotid intima-media thickness (IMT) study is indicated for the following conditions:

  • Atherosclerotic Burden Evaluation This procedure is performed to assess the extent of atherosclerosis in the common carotid artery, which can provide insights into the overall cardiovascular health of the patient.
  • Coronary Heart Disease Risk Factor Assessment The IMT study is utilized to evaluate risk factors associated with coronary heart disease, helping to identify patients who may be at increased risk for cardiovascular events.

2. Procedure

The common carotid intima-media thickness (IMT) study involves several key procedural steps that ensure accurate imaging and assessment of the carotid artery.

  • Step 1: Patient Preparation The patient is positioned comfortably, typically lying down, to allow for optimal access to the neck area. The skin over the common carotid artery is cleaned to ensure that the ultrasound transducer can make good contact and obtain clear images.
  • Step 2: Ultrasound Imaging A gel is applied to the skin to facilitate the transmission of sound waves. The ultrasound transducer is then placed on the skin over the common carotid artery. High-frequency sound waves are emitted, which bounce off the arterial walls and create images of the intima-media thickness.
  • Step 3: Image Acquisition The ultrasound technician captures multiple images of the common carotid artery from various angles. These images are essential for accurately measuring the thickness of the intima-media layer and identifying any atherosclerotic plaques present.
  • Step 4: Data Analysis The acquired images are processed using specialized computer software that analyzes the thickness of the intima-media. This software quantifies the measurements and documents the presence and extent of any atherosclerotic changes in the artery.

3. Post-Procedure

After the common carotid intima-media thickness (IMT) study is completed, the patient may resume normal activities immediately, as the procedure is non-invasive and does not require any recovery time. The results of the study are typically reviewed by a healthcare provider, who will discuss the findings with the patient. Depending on the results, further evaluation or management may be recommended to address any identified cardiovascular risks. It is important for patients to follow up with their healthcare provider to understand the implications of the IMT study results and to discuss any necessary lifestyle modifications or treatments.
