74177 CPT Code: CT Abdomen & Pelvis With Contrast

Last Updated: January 7, 2026

In the past, billing for a CT of the abdomen and a CT of the pelvis required two separate codes. Now, they are permanently bundled into combination codes. CPT 74177 represents a CT of the Abdomen and Pelvis with contrast.

The Combination Codes

If you scan both the abdomen and pelvis during the same session, you must use the combo codes:

  • 74176: Without contrast.
  • 74177: With contrast.
  • 74178: Without contrast, followed by with contrast.

Billing a standalone abdomen CT (74160) and a standalone pelvis CT (72193) on the same day will trigger an NCCI unbundling denial.

Medical Necessity

Verify Medical Necessity

Don't risk a denial. See if your ICD-10 code is on the approved Medicare LCD list.

This code is heavily utilized for appendicitis, diverticulitis, and oncology staging. Ensure your ICD-10 code (e.g., R10.9 ↗ - Unspecified abdominal pain) justifies scanning both anatomical regions.

NCCI Edits

Oral contrast alone does not qualify a scan as "with contrast." The contrast must be administered intravenously (IV) or intra-articularly to use the "with contrast" codes.
