What 95812 covers
This service records electrical activity from the brain, typically through scalp electrodes, for 41–60 minutes. EEG technologists commonly obtain the recording in a hospital or outpatient neurodiagnostic laboratory, while a physician—often a neurologist—interprets the tracing and prepares a report. The study may help evaluate suspected seizures, episodic altered awareness, or encephalopathy when a longer recording is needed than a shorter routine EEG provides.
Select the code based on the EEG recording duration, not the time spent interpreting it: the documented recording must fall within 41–60 minutes. The record should support the duration and include the interpreted findings and report. CMS separately prices the professional interpretation component with modifier 26 and the technical component, including equipment and staff, with modifier TC. Reporting the code without either modifier represents the global service.
