2025 CPT code 74160

Computed tomography of the abdomen with contrast material(s).

Use 74150 for a CT scan of the abdomen without contrast. Use 74170 for a CT of the abdomen where both non-contrast and contrast scans are done during the same session.

Modifiers such as 26 (professional component) and TC (technical component) may be applicable. Modifier 26 is used when only the professional interpretation of the study is being billed, while TC is used when only the technical component (performance of the scan) is being billed.

Medical necessity for this procedure must be established by the referring physician. The documentation should clearly demonstrate a clinical indication for the CT scan with contrast based on the patient's symptoms, signs, and medical history. The rationale for using contrast should also be documented, explaining how it will aid in the diagnosis or treatment planning.

While a radiology technician typically positions the patient and operates the CT scanner, a radiologist is responsible for reviewing and interpreting the resulting images, making a diagnosis, and communicating the findings to the referring physician.

In simple words: A specialized X-ray, called a CT scan, is taken of your belly.A dye, called contrast, is used to help the doctor see the organs and structures in your belly more clearly. This dye might be given to you to drink or through an IV in your arm. The scan creates detailed pictures that help the doctor diagnose problems.

This code represents a computed tomography (CT) scan of the abdomen performed with the administration of contrast material(s). The contrast enhances the visibility of specific organs and structures within the abdomen, aiding in the diagnosis of various conditions.The procedure typically involves oral and/or intravenous administration of a contrast agent, followed by cross-sectional imaging of the abdomen using a CT scanner. A radiologist then interprets the images.

Example 1: A patient presents with abdominal pain and suspected appendicitis. A CT scan of the abdomen with contrast is ordered to visualize the appendix and confirm the diagnosis., A patient with a history of kidney stones experiences recurrent flank pain. A CT abdomen with contrast is performed to evaluate for the presence and location of stones within the urinary tract., A patient involved in a motor vehicle accident presents with blunt abdominal trauma. A CT scan of the abdomen with contrast is ordered to assess for internal injuries and bleeding.

Documentation should include the reason for the CT scan, the type and route of contrast administration, relevant patient history (including allergies and prior reactions to contrast), and the radiologist's interpretation of the images, including any identified abnormalities.

** Information about the type of contrast material used (e.g., iodine-based, barium-based) and the specific areas of the abdomen imaged may also be included in the documentation. Be aware of potential complications of contrast administration, such as allergic reactions.
