CPT® Code 75573

Computed tomography, heart, with contrast material, for evaluation of cardiac structure and morphology in the setting of congenital heart disease (including 3D image postprocessing, assessment of left ventricular [LV] cardiac function, right ventricular [RV] structure and function and evaluation of vascular structures, if performed)

Computed tomography (CT) of the heart is a sophisticated imaging technique that utilizes multiple, narrow X-ray beams directed around a single rotational axis to capture a series of two-dimensional (2D) images of the heart and surrounding structures from various angles. This specific procedure, identified by CPT® Code 75573, is particularly focused on evaluating cardiac structure and morphology in patients with congenital heart disease. The process begins with the acquisition of non-contrast images, which may be necessary for initial assessment. Following this, a contrast material is injected through a previously established intravenous line, enhancing the visibility of the heart and major vessels in the subsequent images. The use of contrast material is crucial as it improves the differentiation of structures within the heart and vascular system, allowing for a more detailed evaluation. Once the images are obtained, a specialized computer software program processes the data to reconstruct three-dimensional (3D) images of the heart and great vessels. This advanced imaging capability enables the physician to produce thin, cross-sectional slices of the heart, facilitating a comprehensive assessment of both the left ventricular (LV) and right ventricular (RV) structures and functions. The evaluation may also extend to related vascular structures, providing a holistic view of the cardiovascular anatomy. After the imaging is completed, the physician reviews the findings and generates a dictated report that summarizes the results of the evaluation, which is essential for guiding further clinical management and treatment decisions in patients with congenital heart disease.
