HCPCS 74178

Computed tomography, abdomen and pelvis; without contrast material in one or both body regions, followed by contrast material(s) and further sections in one or both body regions

AI EXPLANATION: A CT scan of the abdomen and pelvis is an imaging test that uses rotating X-ray equipment and computer processing to create detailed cross-sectional pictures of the internal organs, blood vessels, and soft tissues throughout the midsection and lower torso. During this specific examination, images are captured both before and after a contrast agent is administered, which helps highlight specific structures and abnormalities more clearly on the final scans.
