CPT code 74176: CT abdomen and pelvis, without contrast2026 Medicare rate & RVUs

Medicare pays $183.04 for 74176 nationally in the office. Local office rates run $163.97–$241.76.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 74176 covers

This noncontrast CT images both the abdomen and pelvis, usually from the lung bases through the pubic symphysis. A common use is a renal stone protocol for flank pain or hematuria. It may also be ordered when IV contrast is avoided because of severe kidney impairment or a prior contrast reaction, including evaluation for free air, hemorrhage, or bowel obstruction. Technologists acquire the images in emergency departments, hospital imaging departments, or freestanding centers; a radiologist interprets the study.

Report 74176 once when both regions are imaged without IV contrast, rather than billing separate abdomen and pelvis CT codes. Oral or rectal contrast alone does not change the study to a with-contrast CT. The global code includes image acquisition and interpretation; modifier 26 identifies interpretation alone, and modifier TC identifies the technical portion when separately billed under the physician fee schedule. CMS diagnostic imaging multiple-procedure reduction can affect both components when eligible imaging studies are furnished together; the professional reduction depends on the same physician interpreting the studies in the same session. Documentation should identify both regions, IV contrast status, the indication, and findings.
