2025 CPT code 95705
(Active) Effective Date: N/A Revision Date: N/A Neurology - Electroencephalography (EEG) Medicine Services and Procedures > Neurology and Neuromuscular Procedures Feed
Unmonitored EEG, without video, 2-12 hours; technical description by EEG technologist.
Modifiers may apply depending on the circumstances.Refer to the CPT guidelines for specific modifier use rules.
Medical necessity is established by the presence of symptoms or conditions necessitating the evaluation of brain electrical activity, such as suspected epilepsy, altered mental status, and other neurological disorders.Appropriate clinical documentation should support this.
EEG technologist is responsible for setup, takedown (if performed), patient education, performing and documenting review of the EEG data to assure the integrity and quality of the recording, and creating a technical description. The physician or other qualified health care professional is responsible for interpretation and report generation.
In simple words: This code covers a brainwave test (EEG) that lasts 2 to 12 hours without video. A technician sets up the equipment, explains the procedure, and reviews the results, creating a summary report. The technician does not actively monitor the test while it runs.
This CPT code encompasses the technical component of an unmonitored long-term electroencephalography (EEG) recording without video, lasting between 2 and 12 hours.It includes EEG setup, takedown (if performed), patient/caregiver education, data review by an EEG technologist, and creation of a technical description summarizing the findings.The recording is unmonitored, meaning there is no real-time monitoring by an EEG technologist during the entire recording period. Diagnostic EEG recording is an essential component. A minimum of eight EEG channels must be utilized.
Example 1: A patient presents with suspected epilepsy.A 6-hour unmonitored EEG without video is ordered to assess for seizure activity. Code 95705 is reported for the technical component of this study., A patient admitted to the ICU is experiencing altered mental status. A 12-hour unmonitored EEG without video is used for monitoring and detection of seizure activity. Code 95705 is reported for the technical component., A patient with a history of seizures undergoes a 2-hour unmonitored EEG (without video) to assess for seizure activity before initiation of a new medication. Code 95705 is reported for the technical component.

** This code should only be reported when the criteria for unmonitored EEG are met, otherwise appropriate monitoring codes (95706, 95707, etc.) should be used instead.The professional interpretation component should be billed separately with the appropriate code(s) from 95717-95726.Always verify payer-specific guidelines and coding policies.
