CPT® Code 73200

Computed tomography (CT) of the upper extremity is a diagnostic imaging procedure that provides detailed visualization of the tissues and bone structure of the arm. This technique employs multiple, narrow X-ray beams that are directed around a single rotational axis, capturing a series of two-dimensional (2D) images from various angles. The absence of contrast material in CPT® Code 73200 means that the images are obtained without the use of any enhancing agents, allowing for the assessment of the arm's internal structures based solely on the natural contrast of the tissues. The data collected during the scan is processed by computer software, which generates several images of thin, cross-sectional slices of the targeted area. These 2D slices can be stacked to create three-dimensional models of the arm, offering a comprehensive view of its anatomy. During the procedure, the patient is positioned on a table that slides into the CT scanner, where the imaging takes place. The physician subsequently reviews the CT scan to identify any abnormalities, such as tumors, abscesses, or masses, and evaluates the bones for degenerative conditions, fractures, or injuries resulting from trauma. Additionally, the scan aids in determining the underlying causes of pain or swelling in the upper extremity.
