What 75574 covers
This service uses CT and intravenous contrast to create angiographic images of the heart, with image processing that supports review of the coronary arteries and cardiac structures. It is commonly performed in an outpatient imaging department or hospital by CT technologists, with interpretation by a radiologist or cardiologist. Clinicians may use coronary CTA when evaluating suspected coronary artery disease, including in patients with chest discomfort who need an anatomic assessment of coronary vessels.
Select the code for the contrast-enhanced cardiac angiographic study, rather than a noncontrast calcium score or a CT focused on structural heart detail. The record should support the clinical indication, contrast-enhanced acquisition, image processing, and the interpreting professional’s findings. The service may be billed globally, or split into professional interpretation with modifier 26 and technical services with modifier TC. When multiple diagnostic imaging procedures are billed, the CMS multiple procedure reduction applies to both the technical and professional components.

How to choose
- 75571Calcium scoring
- Use 75571 for noncontrast coronary calcium measurement. Use 75574 when the service is contrast-enhanced CT angiography of the heart.
- 75572Cardiac CT
- 75572 focuses on cardiac structural detail by CT. 75574 is the angiographic study used to evaluate coronary vessels.
- 75580CT-derived FFR
- 75580 describes computational analysis derived from coronary CTA data; it does not report the CTA acquisition itself. Report 75574 for the angiographic study.
- 75561Cardiac MRI
- 75561 is cardiac MRI with contrast, while 75574 uses CT angiography. Choose based on the imaging method actually performed.
75574 billing questions
How is this different from 75571?
75574 is contrast-enhanced CT angiography used to visualize coronary vessels and cardiac anatomy. 75571 is a noncontrast CT used to measure coronary artery calcium.
Is 3D image processing separately reported?
The image processing is included in 75574. Do not separately report a 3D rendering code for the processing included in this service.
Can the professional and technical services be billed separately?
Yes. Report modifier 26 for the professional interpretation or TC for the technical service; without either modifier, the code represents the global service.
Does the multiple procedure reduction affect both components?
Yes. When the diagnostic imaging multiple procedure reduction applies, it affects both the technical and professional components.
When might 75580 be reported with this study?
75580 may be reported for qualifying noninvasive computational analysis of coronary CT angiography data. It is an add-on service, not a replacement for the CTA acquisition reported with 75574.
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.
