CPT® Code 93352

Add-On Code

Use of echocardiographic contrast agent during stress echocardiography (List separately in addition to code for primary procedure)

The CPT® Code 93352 refers to the use of an echocardiographic contrast agent during a stress echocardiography procedure. This code is specifically designated as an add-on code, meaning it is reported in conjunction with a primary procedure code for stress echocardiography. The use of a contrast agent enhances the visualization of cardiac structures and dynamics, allowing for a more detailed assessment of the heart's function during stress testing. The contrast agent is administered intravenously and is titrated to achieve optimal left ventricular opacification, which is crucial for accurate imaging. This procedure typically involves a baseline echocardiogram at rest, followed by a stress component where the patient's heart is subjected to increased workload, either through exercise or pharmacological means. The echocardiographic images are captured in real-time, providing valuable insights into the heart's performance under stress conditions. The integration of contrast agents in this context is essential for identifying abnormalities in cardiac structure and function that may not be as easily discernible without their use.
