CPT® Code 72133

Computed tomography (CT) of the lumbar spine is a diagnostic imaging procedure that utilizes advanced X-ray technology to create detailed images of the lower back region. This procedure involves the use of multiple, narrow X-ray beams that rotate around a single axis, capturing a series of two-dimensional images from various angles. The resulting images provide a comprehensive view of the lumbar spine, allowing for the assessment of its structure and any potential abnormalities. In this specific procedure, referred to by CPT® Code 72133, the imaging is performed initially without the use of contrast material, followed by the administration of contrast agents to enhance the visibility of the spinal structures. The contrast material, typically an iodine-based dye, helps to delineate the anatomy more clearly, making it easier for healthcare professionals to identify issues such as bone diseases, fractures, injuries, or congenital defects in the spine, particularly in pediatric patients. The CT scanner captures thin, cross-sectional slices of the lumbar spine, which can be digitally reconstructed into three-dimensional models for further analysis. This comprehensive imaging technique is crucial for accurate diagnosis and treatment planning in patients presenting with lumbar spine-related symptoms.
