Computed tomography (CT) of the heart with contrast material, evaluating cardiac structure and morphology in congenital heart disease, including 3D post-processing, assessment of left ventricular function, right ventricular structure and function, and vascular structures (if performed).
Modifiers 26 (professional component) and TC (technical component) may be appended as appropriate.
Medical necessity for this procedure is established when clinical findings (e.g., physical exam, electrocardiogram) suggest the presence of a congenital heart defect or when follow-up imaging is required after a prior cardiac procedure. The detailed imaging provided by this procedure is crucial for diagnosis and management.
The radiologist is responsible for administering the contrast material, operating the CT scanner, acquiring the images, performing 3D post-processing (if indicated), interpreting the images, and generating a report.
In simple words: This test uses a CT scan and special dye to take detailed pictures of the heart to check for birth defects.The pictures are processed to show the heart's function and structure in 3D, helping doctors find any problems.
This CPT code (75573) encompasses a computed tomography (CT) scan of the heart using contrast material.The examination is specifically indicated for evaluating cardiac structure and morphology in patients with congenital heart disease. The procedure includes three-dimensional (3D) image post-processing, assessment of left ventricular (LV) cardiac function, evaluation of right ventricular (RV) structure and function, and assessment of vascular structures, if performed.The contrast administration is intravascular.
Example 1: A newborn infant presents with a suspected congenital heart defect.A CT scan with contrast is performed to evaluate the anatomy and function of the heart chambers and great vessels., A young adult is referred for evaluation of a murmur.A cardiac CT with contrast is used to assess for structural abnormalities like atrial septal defect or ventricular septal defect., A patient with a history of repaired Tetralogy of Fallot undergoes follow-up imaging with cardiac CT to assess for the presence of any residual abnormalities or complications.
* Physician's order specifying the need for cardiac CT with contrast.* Patient's medical history, including any known congenital heart conditions or prior cardiac procedures.* Images from the CT scan.* Radiologist's report including measurements of cardiac chambers, ejection fraction, and any identified abnormalities.
** This procedure is typically performed with intravenous contrast material.The choice of contrast agent is at the discretion of the radiologist, taking into account patient factors such as allergies and renal function.Pre-procedural instructions to the patient may include fasting or other preparation guidelines.
