CPT code 74150: CT abdomen, without contrast2026 Medicare rate & RVUs in California

Medicare pays $144.80–$181.23 for 74150 in the office in California, from Chico, CA to San Benito County, CA. Which amount applies depends on the service address.

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

What 74150 covers

This service uses computed tomography to produce cross-sectional images of the abdomen without contrast material. A radiologic technologist typically acquires the images in a hospital or imaging center, and a radiologist interprets them. It may be selected when the clinical question calls for noncontrast abdominal imaging, including evaluation for suspected urinary calculi. The documented study must cover the abdomen rather than both the abdomen and pelvis as a combined examination.

Report 74150 when the performed study is limited to the abdomen and uses no contrast; the imaging order and report should support the anatomy examined and contrast protocol. The professional component represents the physician’s interpretation, while the technical component represents the equipment and staff used to perform the scan. Bill without a component modifier for the global service, or use modifier 26 or TC for the respective component. CMS applies the diagnostic imaging multiple procedure reduction to both the technical and professional components.
