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.
This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
