CPT® Code 74170

Computed tomography (CT) of the abdomen is a diagnostic imaging procedure that utilizes advanced X-ray technology to create detailed images of the internal structures within the abdominal cavity. This procedure is particularly valuable for visualizing various tissues and organs, allowing healthcare professionals to assess conditions that may not be visible through standard imaging techniques. The process begins with the patient being positioned on a table that slides into the CT scanner, which is a large, doughnut-shaped machine. During the scan, multiple narrow X-ray beams rotate around the patient, capturing a series of two-dimensional (2D) images from different angles. These images are then processed by computer software to generate thin, cross-sectional slices of the abdomen, which can be stacked to create three-dimensional (3D) models for enhanced visualization. In the case of CPT® Code 74170, the procedure is performed in two phases: initially, a CT scan is conducted without the use of contrast material, followed by the administration of contrast agents to enhance the visibility of the abdominal structures. The contrast material, typically an iodine-based dye, is introduced to improve the differentiation of tissues and highlight abnormalities. This dual-phase approach allows for a comprehensive evaluation of the abdomen, aiding in the diagnosis of various conditions such as abdominal pain, swelling, fever, appendicitis, kidney stones, tumors, abscesses, hernias, infections, and internal injuries. After the imaging is complete, the physician carefully reviews the resulting images, identifies any abnormalities, and documents a detailed interpretation of the findings for further clinical decision-making.
