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.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

95812 billing questions

When should 95812 be selected instead of 95813?

Use 95812 when the EEG recording lasts 41–60 minutes. A recording lasting 61–119 minutes falls in 95813.

Is the code selected by interpretation time?

No. The time distinction is based on the EEG recording duration; document the recording time in the study record.

How are the professional and technical portions reported?

Report modifier 26 for the professional interpretation or modifier TC for the technical service. Without either modifier, the code represents the global service.

How does 95812 differ from 95816?

95812 identifies an extended EEG by its 41–60-minute recording duration. 95816 describes an EEG performed in awake and drowsy states.

What documentation supports 95812?

Document the EEG recording duration, the study findings, and the interpreting physician’s report. The recorded duration should support the 41–60-minute range.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
