CPT® Code 76775

A limited retroperitoneal ultrasound, identified by CPT® Code 76775, is a diagnostic imaging procedure that utilizes real-time ultrasound technology to visualize the retroperitoneal space, which includes structures such as the kidneys, aorta, and lymph nodes. During this procedure, the patient is positioned supine, allowing optimal access to the abdominal area. The application of acoustic coupling gel to the skin enhances the transmission of ultrasound waves, facilitating clearer imaging. A transducer is then placed firmly against the skin and moved across the abdomen to capture images of the retroperitoneal region. The ultrasound machine emits high-frequency sound waves that penetrate the body and reflect off internal structures, creating echoes that are converted into visual images. These images are crucial for identifying any abnormalities within the retroperitoneal area, as they can reveal characteristics that assist in forming a definitive diagnosis. After the examination, the physician reviews the captured images and provides a comprehensive written interpretation of the findings. It is important to note that CPT® Code 76775 is specifically designated for limited examinations, in contrast to CPT® Code 76770, which encompasses a complete retroperitoneal ultrasound that includes a broader assessment of the kidneys, abdominal aorta, common iliac artery origins, and inferior vena cava.
