CPT Code 74178: CT Abdomen and Pelvis With and Without Contrast

A CT abdomen with contrast is a diagnostic imaging test that uses contrast material, typically iodine-based, administered intravenously to enhance the visibility of abdominal organs and structures in detailed images. It helps detect and evaluate a wide range of conditions, including infections (like appendicitis or diverticulitis), inflammation (such as pancreatitis), tumors, vascular abnormalities (e.g., aneurysms), and other pathologies affecting organs like the liver, kidneys, pancreas, and intestines.

The CPT codes for CT abdomen and pelvis imaging depend on whether contrast material is used. CPT 74176 is used for CT scans of the abdomen and pelvis performed without contrast; 74177 applies when the scan is done with contrast; and 74178 is used when the scan includes both without and with contrast phases during the same session.

CPT code 74178 refers to a CT scan of the abdomen and pelvis performed both without and with contrast material, providing comprehensive imaging before and after contrast administration. In contrast, 74177 is a CT scan of the abdomen and pelvis performed with contrast material only, without pre-contrast images.
