CPT Code 75574: Cardiac CT with Contrast and 3D Reconstruction

What is cardiac CT angiography with 3D rendering?

CPT code 75574 describes a computed tomography (CT) angiography of the heart, native coronary artery, and coronary artery bypass grafts using contrast material and 3D image post-processing. This advanced cardiac CT scan is primarily used to evaluate atherosclerotic heart disease, myocardial infarction, or congenital and structural issues of the heart and cardiac function.

This procedure is often performed when a physician suspects angina pectoris, unstable angina pectoris, stenosis, or complications involving a transplanted heart, aortic valve, or cardiac structure. Using a high-resolution CT scanner and advanced imaging technology, this test provides detailed visualization of the coronary arteries and grafts, allowing healthcare providers to accurately assess function and guide treatment.

When is cardiac CT angiography with 3D rendering (CPT 75574) ordered?

Cardiac CT angiography with 3D rendering is generally ordered to evaluate heart related conditions such as chest pain, suspected coronary artery disease (CAD), myocardial infarction, or complications involving coronary artery bypass grafts.

Physicians use this advanced imaging to determine the presence of stenosis, atherosclerosis, or graft insufficiency. It is also helpful in assessing structural heart abnormalities, cardiac function, and planning interventions for complex cases including transplanted hearts or aortic valve disease.

CPT code 75574 documentation requirements

To ensure coding accuracy and Medicare or commercial coverage, include the following in your report:

• Clinical indications (e.g., chest pain, chronic angina, suspected atherosclerosis)
• Specific cardiac CT protocol used to assess the native coronary artery and bypass grafts
• Type and volume of contrast material
• Confirmation that 3D reconstruction was performed
• Radiologist's interpretation, including findings for the heart, coronary arteries, and cardiac function
• Note any limitations due to patient condition, morphology, or motion artifacts

CPT code 75574 billing guidelines

To report CPT 75574 correctly, follow these billing and coding information rules:

• Report once per session, regardless of the number of grafts or vessels imaged.
• Use modifier -26 (professional component) or -TC (technical component) when billing separately.
• Use global billing when both components are provided by the same provider.
• Ensure the 3D rendering is performed and included in documentation (you don’t need to bill CPT 76377 separately).
• Do not report with CPT 71275 unless imaging was ordered and performed for a distinct non-cardiac reason.
• Pair with applicable ICD-10 codes (e.g., I25.10 for CAD, I20.9 for angina pectoris)

This service must be conducted using equipment with appropriate cardiac capabilities and interpreted by a credentialed provider.

Other relevant CPT codes

• 71275 – CTA of the chest (noncoronary), with contrast material(s) and may involve noncontrast images and image postprocessing
• 75572 - CTA, heart, with contrast material, for evaluation of cardiac structure and morphology (including 3D image postprocessing, assessment of cardiac function, and evaluation of venous structures, if performed)
• 75573 – CTA, heart, with contrast material, for evaluation of cardiac structure and morphology in the setting of congenital heart disease (including 3D image postprocessing, assessment of LV cardiac function, RV structure and function and evaluation of venous structures, if performed)
