CPT® Code 95709

Electroencephalogram (EEG), without video, review of data, technical description by EEG technologist, each increment of 12-26 hours; with intermittent monitoring and maintenance

The CPT® Code 95709 refers to an electroencephalogram (EEG) procedure that involves a long-term continuous recording of brain wave activity without video. This procedure is specifically designed to capture and analyze brain electrical activity over an extended period, ranging from 12 to 26 hours. The recording time is measured from the moment the actual EEG recording begins and continues for the duration of the recording session. The primary purpose of conducting a long-term EEG is to diagnose various neurological conditions, particularly seizure disorders. It helps in identifying the specific type and location of seizures, monitoring the effectiveness of ongoing treatment, and determining the potential for surgical intervention in cases of epilepsy. Additionally, long-term EEGs can be crucial for seriously ill patients, as they allow healthcare providers to screen for new or adverse neurological changes that may arise. The technical aspects of this procedure include the EEG technologist's responsibilities, which encompass uploading the data generated by the EEG equipment, reviewing the raw data, annotating and editing recognized events—both those generated by the patient and those detected by the machine. Furthermore, the technologist is responsible for storing or archiving the reviewed data for further analysis by a physician or qualified personnel. A comprehensive written report is also generated, documenting the technologist's review of the data and any technical interventions performed during the procedure. This code is specifically used when intermittent monitoring and maintenance are provided, ensuring that the quality of the EEG recording is overseen, with real-time data reviews conducted at least every two hours throughout the entire recording period.
