CPT® Code 0637T

Computed tomography (CT) of the breast is a sophisticated imaging technique that utilizes advanced X-ray technology and computer processing to create detailed cross-sectional images of both breasts. This procedure is particularly valuable in the evaluation of breast tissue, allowing for the identification of abnormalities that may not be visible through traditional imaging methods. During the CT scan, the patient is carefully positioned on an examination table, and an initial scan is conducted to establish the appropriate starting position for the imaging process. As the table gradually moves through the CT scanner, a series of X-ray beams and detectors rotate around the area being examined, capturing data on the varying levels of radiation absorption by the breast tissue. This information is then processed by a specialized computer program, which generates two-dimensional (2D) cross-sectional images that are displayed on a monitor for analysis. When indicated, the procedure may also include three-dimensional (3D) rendering, which enhances the visualization of the breast structures. This advanced rendering can involve techniques such as shaded surface rendering, volumetric rendering, maximum intensity projections (MIPs), fusion imaging, and quantitative analysis, providing a comprehensive view of the breast anatomy. It is important to note that CPT® Code 0637T is specifically used when intravenous contrast material is administered prior to the CT scan, enhancing the visibility of certain tissues and potential abnormalities. In contrast, CPT® Code 0636T is designated for CT scans performed without intravenous contrast, while CPT® Code 0638T applies when a CT scan is initially conducted without contrast, followed by the administration of contrast for additional imaging. After the completion of the scan, the physician reviews the images, identifies any potential issues, and prepares a written interpretation of the findings for further evaluation and management.
