CPT® Code 74150

Computed tomography (CT) of the abdomen, as described by CPT® Code 74150, is a diagnostic imaging procedure that provides detailed visualization of the abdominal organs and tissues without the use of contrast material. This imaging technique employs multiple narrow X-ray beams that rotate around a single axis, capturing a series of two-dimensional (2D) images from various angles. The absence of contrast material means that the images are generated based solely on the natural density differences of the tissues within the abdomen. The data collected during the scan is processed by computer software to create thin, cross-sectional slices of the targeted area, which can be further compiled into three-dimensional (3D) models for enhanced visualization. During the procedure, the patient lies on a table that moves into the CT scanner, allowing for the acquisition of images of the abdomen. The physician interprets these images to identify potential causes of abdominal symptoms such as pain, swelling, or fever, and to investigate other conditions like appendicitis, kidney stones, tumors, abscesses, hernias, infections, or internal injuries. The findings from the CT scan are documented in a written report, which includes any noted abnormalities and the physician's interpretation of the results.
