CPT® Code 95824

An electroencephalogram (EEG) is a diagnostic procedure that measures the electrical activity of the brain. In the context of CPT® Code 95824, the EEG is specifically utilized to evaluate suspected cerebral death in a comatose patient. This procedure is critical in determining the presence or absence of brain activity, which is essential for making informed decisions regarding the patient's prognosis and potential end-of-life considerations. During the EEG, a trained technician applies a series of sixteen to eighteen electrodes to the patient's scalp, using a conductive sticky paste to ensure optimal contact. These electrodes are connected to an amplifier and a recording device, which captures the brain's electrical signals. The recording process transforms these signals into visual representations, typically displayed as wavy lines on graph paper. The duration of the EEG for patients suspected of cerebral death is a minimum of 30 minutes, allowing sufficient time to assess any electrical brain activity. Following the procedure, a physician reviews the recorded data and provides a comprehensive written interpretation of the findings, which is crucial for clinical decision-making regarding the patient's condition.
