What 95822 covers

Code 95822 describes an electroencephalogram recorded while the patient is asleep or comatose, rather than an awake-and-asleep routine EEG. Scalp electrodes and EEG equipment capture cerebral electrical activity; an EEG technologist generally performs the recording, and a physician with EEG expertise interprets it. Hospital and outpatient neurodiagnostic services may use this code when the documented recording is limited to sleep or coma, including evaluations of seizures or abnormal brain function.

Choose the code based on the recording state, not just the reason for testing. An EEG that includes awake and asleep phases is reported with 95819; an awake-and-drowsy study is reported with 95816. Documentation should support the patient's state during the recording and the EEG services performed. CMS recognizes a professional component for interpretation and a technical component for equipment and staff: report modifier 26 for the professional component, modifier TC for the technical component, or neither for 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.

95822 billing questions

How does 95822 differ from 95819?

95822 is for an EEG recorded during sleep or coma only. Use 95819 when the study includes both awake and asleep recording.

How does 95822 differ from 95816?

95822 describes sleep-only or coma-only recording. Code 95816 is for an EEG that includes awake and drowsy recording.

Can the professional and technical portions be billed separately?

Yes. Modifier 26 identifies the interpretation, and modifier TC identifies the equipment and staff; billing without either modifier represents the global service.

Is the code selected by recording duration?

The distinguishing feature of 95822 is that recording is limited to sleep or coma. Codes 95812 and 95813 identify EEGs by recording duration.

What should the record support?

Document that the EEG was recorded during sleep or coma, along with the recording performed and the physician's interpretation.

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.
