CPT® Code 72126

Computed tomography (CT) of the cervical spine is a diagnostic imaging procedure that utilizes advanced X-ray technology to create detailed images of the cervical region of the spine. This procedure employs multiple, narrow X-ray beams that rotate around a single axis, capturing a series of two-dimensional (2D) images from various angles. The use of contrast material, typically an iodine-based dye, enhances the visibility of structures within the cervical spine, allowing for clearer and more precise imaging. The contrast material can be administered either intrathecally, which involves injecting it into the space surrounding the spinal cord at the C1-C2 level or another cervical level, or intravenously, depending on the clinical requirements. The CT scanner processes the collected data through sophisticated computer software, generating several thin, cross-sectional 2D slices of the cervical spine. These slices can be stacked to create three-dimensional (3D) models, providing a comprehensive view of the spine's anatomy. This imaging technique is particularly useful for diagnosing various conditions, including bone diseases, fractures, injuries, and congenital anomalies in the cervical spine, especially in pediatric patients. It is important to note that this procedure differs from CPT® Code 72125, which does not utilize contrast material, and from CPT® Code 72127, which involves imaging both with and without contrast material.
