Extended Electroencephalogram (EEG), Over One Hour

Oregon rates for HCPCS 95813

Sensors placed on the scalp record the brain's electrical activity continuously over a longer session than a routine brain wave test, typically lasting more than an hour. The extra recording time increases the chance of capturing abnormal patterns, such as seizure activity, that might not appear during a shorter test. It is noninvasive and doesn't involve sampling from inside the body.
