CPT® Code 93316

Transesophageal echocardiography (TEE) is a specialized imaging technique used to evaluate congenital cardiac anomalies. This procedure involves the use of a miniature high-frequency ultrasound transducer that is mounted on the tip of a flexible tube, known as a probe. The probe is carefully passed through the patient's mouth and advanced into the esophagus, where it is positioned behind the heart. This unique positioning allows the transducer to direct ultrasound waves directly into the heart, providing a clear and detailed view of its structures. The sound waves emitted by the transducer are reflected back to it, and these echoes are processed by a computer to create real-time images of the heart, which are displayed on a video screen. TEE is particularly beneficial for obtaining comprehensive evaluations of both the functional and anatomical aspects of the heart, including the left and right chambers, heart valves, pericardium, and major blood vessels such as the aorta and pulmonary vessels. The procedure allows for multiple views by manipulating the transducer within the esophagus, enhancing the quality of the assessment. Additionally, TEE employs selective M-mode recording, also referred to as T-M mode, which provides specific time-motion information from a stationary beam superimposed on the two-dimensional images. This M-mode is primarily utilized for precise cardiac measurements, such as assessing septal wall thickness and valve timing. It is important to note that CPT® Code 93316 is specifically designated for instances where only the placement of the transesophageal probe is performed, distinguishing it from other related codes that involve additional steps such as image acquisition and reporting of findings.
