Transesophageal echocardiography for congenital cardiac anomalies; including probe placement, image acquisition, interpretation and report

Transesophageal echocardiography (TEE) is a specialized imaging procedure utilized to assess congenital cardiac anomalies. This technique involves the use of a miniature high-frequency ultrasound transducer that is mounted on the tip of a flexible tube, referred to as a probe. The probe is carefully passed through the patient's mouth and advanced into the esophagus, positioning the transducer behind the heart. This strategic placement allows for the effective transmission of ultrasound waves directly into the heart. As the sound waves bounce back to the transducer, they are converted by a computer into detailed images of the heart, which are displayed on a video screen. TEE is particularly advantageous as it provides real-time ultrasound scanning, enabling the visualization of both the heart's structure and its movement during the procedure. The procedure is designed to obtain multiple views by maneuvering the transducer within the esophagus, facilitating a thorough evaluation of the heart's left and right chambers, valves, pericardium, and other critical structures, including the aorta, pulmonary vessels, and vena cava. Additionally, TEE employs selective M-mode recording, also known as T-M mode, which offers specific time-motion information from a stationary beam that is superimposed on the two-dimensional image. In this mode, depth is represented along the vertical axis while time is depicted on the horizontal axis, making it particularly useful for precise cardiac measurements, such as septal wall thickness and valve timing. The use of CPT® Code 93315 is appropriate when the physician conducts probe placement, image acquisition, and provides a written report of the findings. In contrast, CPT® Code 93316 is designated for instances where only the transesophageal probe placement is performed, while CPT® Code 93317 is applicable when only image acquisition and a written report of findings are completed.
