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.
