CPT code 75574 designates a diagnostic cardiac computed tomography (CT) study performed with intravascular contrast to evaluate the heart, coronary arteries, and coronary artery bypass grafts. The code also encompasses concurrent imaging of cardiac structures, evaluation of cardiac function, and assessment of venous anatomy when performed as part of the same encounter. This service is central to noninvasive coronary assessment and pre- or post-operative graft evaluation, supporting clinical decision-making for suspected coronary artery disease and structural heart conditions.

Key payers in the national coverage landscape include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Coverage policies across these payers typically address clinical indications, prior authorization requirements, and documentation standards for cardiac CT angiography and related cardiac imaging services.
