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

What 74170 covers

This examination combines unenhanced abdominal CT images with additional images after contrast administration. The unenhanced phase provides a baseline for comparison with contrast enhancement, which can help characterize findings such as an abdominal organ lesion. A radiologic technologist typically performs the scan in a hospital or outpatient imaging center, and a radiologist interprets the images.

Select this code when the documented study covers the abdomen and includes both phases; a single-phase examination belongs to a different code. The order and report should support why both phases were obtained and identify the anatomy imaged. The physician may report the interpretation with modifier 26, the imaging site may report equipment and staff with modifier TC, or the global service may be billed without a component modifier. CMS applies the diagnostic imaging multiple procedure reduction to both the technical and professional components when applicable.

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.
