CPT® Code 78761

Testicular imaging with vascular flow, as defined by CPT® Code 78761, is a diagnostic procedure that utilizes scintigraphy in conjunction with a radiolabeled isotope tracer to assess the vascular perfusion of the testis. This imaging technique is particularly valuable in identifying conditions such as spermatic cord torsion, which is a surgical emergency, as well as epididymitis and orchitis, which are inflammatory conditions of the epididymis and testis, respectively. The procedure begins with the establishment of an intravenous line, through which the radiolabeled isotope tracer is injected into the patient's circulatory system. Following the injection, the patient is positioned on a procedure table, and a gamma camera is strategically placed to capture images of the scrotal area. The imaging process involves obtaining flow studies that document the blood supply to the testis, which can be visualized in cinematic mode, followed by the acquisition of static images that detail the testis, spermatic cords, and surrounding structures. The emitted radioactive energy from the tracer is transformed into visual images, which are then interpreted by the physician, who subsequently generates a comprehensive written report detailing the findings of the study.
