CPT® Code 95812

An electroencephalogram (EEG) with extended monitoring, specifically CPT® Code 95812, refers to a diagnostic procedure that records the electrical activity of the brain for a duration of 41 to 60 minutes. This extended monitoring is crucial for accurately diagnosing various neurological conditions. The EEG is particularly useful in identifying seizure disorders, which are characterized by abnormal electrical activity in the brain. Additionally, it helps in determining the underlying causes of confusion, investigating episodes of unconsciousness, and evaluating head injuries. The procedure can also assist in identifying other brain-related conditions such as tumors, infections, degenerative diseases, or metabolic disturbances. Furthermore, EEGs are employed in the assessment of sleep disorders, providing insights into the brain's activity during different sleep stages. During the procedure, a trained EEG technician applies 16 or more electrodes to the patient's scalp using a conductive paste, ensuring optimal contact for accurate readings. These electrodes are connected to an amplifier and recording device, which captures the brain's electrical signals. The patient is instructed to remain still with their eyes closed while the machine records the brain's activity, which is then displayed as wavy lines on graph paper. To enhance the diagnostic yield, the patient may be asked to hyperventilate or undergo photic stimulation to potentially provoke seizure activity. After the recording session, a physician reviews the data and provides a comprehensive written interpretation of the results, which is essential for guiding further clinical decisions.
