CPT® Code 76506

Echoencephalography, real time with image documentation (gray scale) (for determination of ventricular size, delineation of cerebral contents, and detection of fluid masses or other intracranial abnormalities), including A-mode encephalography as secondary component where indicated

Echoencephalography, as defined by CPT® Code 76506, is a specialized imaging technique utilized to assess the head and cranial cavity. This non-invasive procedure employs a transducer probe that is placed firmly against the scalp, allowing for the transmission of high-frequency sound waves. These sound waves are then converted into a gray scale image, which provides a visual representation of the skull, ventricles, and other cerebral structures. The primary purpose of echoencephalography is to identify abnormal masses, fluid collections, or other intracranial abnormalities. This imaging modality is particularly valuable in diagnosing and monitoring various conditions, including head injuries, intracranial hemorrhages, tumors, and structural anomalies of the brain. Additionally, the procedure may incorporate A-mode encephalography, which involves one-dimensional (1-D) ultrasonic measurements of the skull and/or brain, as a secondary component when indicated. In contrast, real-time ultrasonic measurement employs two-dimensional (2-D) scanning, allowing for the visualization of both the structure and motion over time, enhancing the diagnostic capabilities of the procedure.
