CPT® Code 0716T

The CPT® Code 0716T refers to a procedure known as cardiac acoustic waveform recording, which involves the automated analysis and generation of a coronary artery disease (CAD) risk score. This innovative method utilizes advanced sensors to detect heart sounds and analyze them to assess a patient's risk of obstructive coronary artery disease. The procedure is performed by attaching sensors externally to the patient's chest, specifically positioned to capture sounds generated by blood flow turbulence in the coronary arteries during diastole. Diastole is the phase of the cardiac cycle when the heart muscle relaxes, allowing the heart chambers to fill with blood. The device employs an automated algorithm to process the recorded sounds and calculate the patient's risk of CAD. During the procedure, the patient lies supine, and an adhesive sensor is affixed to the chest, typically to the left of the sternum at the fourth intercostal space. The patient is instructed to hold their breath for eight seconds, repeating this four times, while the heart sounds are recorded. Following the completion of the recordings, the CAD risk score is generated immediately. This test is characterized by its non-invasive nature and absence of radiation exposure, making it a safe option for patients. It is particularly useful in clinical settings to help rule out obstructive coronary artery disease in individuals presenting with symptoms such as shortness of breath.
