CPT® Code 95721

Electroencephalogram (EEG), continuous recording, physician or other qualified health care professional review of recorded events, analysis of spike and seizure detection, interpretation, and summary report, complete study; greater than 36 hours, up to 60 hours of EEG recording, without video

The CPT® Code 95721 refers to a long-term electroencephalogram (EEG) that involves continuous recording of brain wave activity for a duration exceeding 36 hours, but not exceeding 60 hours. This procedure is crucial for capturing and analyzing the electrical activity of the brain, particularly in patients experiencing seizures or other neurological abnormalities. The EEG is performed by a physician or another qualified healthcare professional who reviews the recorded events, conducts an analysis for spike and seizure detection, and provides an interpretation along with a summary report of the findings. The absence of video monitoring distinguishes this code from others that include video electroencephalography (VEEG). The primary purpose of this extended EEG service is to diagnose specific types and locations of seizures, monitor ongoing treatment efficacy, differentiate seizure disorders from other neurological conditions, and evaluate the potential for surgical intervention in epilepsy cases. Additionally, long-term EEG monitoring can be beneficial for critically ill patients to identify any new adverse neurological changes. The professional component of this service encompasses a comprehensive review of the EEG data, culminating in a detailed written report that includes diagnostic interpretations and recommendations based on the recorded results.
