CPT code 95708 represents an unmonitored electroencephalography (EEG) study of 12 to 26 hours duration used to assess brain electrical activity when extended recording is needed but continuous video correlation is not performed. Nationally, prolonged EEG monitoring supports diagnosis and management of seizure disorders, unexplained altered mental status, and other paroxysmal neurological events, making accurate coding and billing important for clinical documentation and payment consistency. Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the clinical service captured by the code, typical sites of service, common modifiers and billing considerations, and an overview of where 95708 fits among related EEG services. The publication also outlines typical billing practices and expected documentation elements needed to support claims. Data not available in the input is noted where applicable, and no state-specific rules are addressed; the content is framed for a national audience.
