CPT® Code 76642

A real-time ultrasound of the breast, designated by CPT® Code 76642, is a diagnostic imaging procedure that focuses on a specific area of the breast, either the right or left side, and includes the axillary region when applicable. This procedure is particularly useful for evaluating breast abnormalities that may have been identified during a physical examination or through mammography. The ultrasound technique allows for the differentiation between solid masses and fluid-filled cysts, as well as the assessment of additional structural features of the abnormal area and the surrounding tissues. During the procedure, the patient is positioned supine, with the arm on the side being examined raised above the head to optimize access to the breast. Acoustic coupling gel is applied to ensure effective transmission of the ultrasound waves, and a transducer is placed firmly against the skin of the breast. The transducer emits ultrasonic wave pulses, which penetrate the breast tissue and are reflected back, creating images based on the echoes received. These images are crucial for evaluating any detected abnormalities, as they help in identifying specific characteristics that may lead to a definitive diagnosis. Unlike a complete unilateral ultrasound examination, which is covered under CPT® Code 76641 and involves a thorough evaluation of all four quadrants of the breast, CPT® Code 76642 is focused on a limited area of interest, allowing for a more targeted assessment. The physician is responsible for reviewing the obtained ultrasound images and providing a comprehensive written interpretation of the findings.
