Extended EEG Monitoring (12-26 Hours)

Illinois rates for HCPCS 95719

Electrodes attached to the scalp continuously record the brain's electrical activity over a defined multi-hour block, roughly 12 to 26 hours, often to capture and characterize seizures that don't occur predictably during a short office visit. A specialized team reviews the full recording afterward to help diagnose or classify a seizure or other neurological condition.
