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.
