CPT® Code 93319

Add-On Code

3D echocardiographic imaging and postprocessing during transesophageal echocardiography, or during transthoracic echocardiography for congenital cardiac anomalies, for the assessment of cardiac structure(s) (eg, cardiac chambers and valves, left atrial appendage, interatrial septum, interventricular septum) and function, when performed (List separately in addition to code for echocardiographic imaging)

3D echocardiography (3DE) is a sophisticated imaging technique that provides detailed visualization of the heart's structures and functions. This procedure is particularly valuable in the management of congenital cardiac anomalies, as it allows for a comprehensive assessment of various cardiac components, including the cardiac chambers, valves, left atrial appendage, interatrial septum, and interventricular septum. The technology employs specialized transducers that can be either small, high-frequency types suitable for pediatric patients or larger versions for adults. These transducers are designed to capture real-time three-dimensional images of the heart while it is in motion, enhancing the clinician's ability to evaluate cardiac morphology and function. The 3DE system utilizes advanced computer post-processing techniques to analyze the acquired datasets, providing critical information that aids in pre-surgical planning and guides interventional catheter placements. The transducers used in 3DE feature a matrix array of thousands of piezoelectric crystals, which are arranged in a grid pattern. This configuration allows for independent activation, focusing, and steering of the ultrasound beam across multiple planes, thereby covering the entire three-dimensional volume necessary for a thorough evaluation. The ultrasound waves emitted by the transducers penetrate the heart, and the reflected sound waves are captured and converted into real-time images displayed on a video monitor. It is important to report CPT® code 93319 separately in addition to the primary echocardiography imaging code when this procedure is performed.
