Computer Analysis of a Brain Wave Recording

South Dakota rates for HCPCS 95957

A specialized computer-based analysis of a previously recorded brain wave study (EEG), used to detect specific patterns associated with seizures, such as brief abnormal spikes in electrical activity. It is typically ordered when a standard reading of the recording needs a more detailed, targeted review for subtle seizure-related activity. This analysis does not involve a new recording session — it works with a recording that has already been captured.
