CPT code 95706 represents an extended electroencephalography (EEG) service lasting between 2 and 12 hours with intermittent monitoring and technologist review and documentation. This technical EEG service does not include video recording and is commonly used for intermediate-duration diagnostic evaluation of brain electrical activity. Nationally, extended EEG services are important for diagnosing seizure disorders, evaluating altered mental status, and guiding neurological care, particularly when routine short-term EEGs are insufficient.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find national benchmarks and payer coverage considerations, clinical context for when an intermediate-duration EEG is appropriate, and operational notes relevant to sites of service such as hospital EEG labs and ambulatory monitoring centers. The publication summarizes common billing modifiers and provides guidance on documentation elements required to support a technical EEG service with technologist interpretation.

This summary equips clinicians, billing professionals, and policy analysts with a concise reference to the clinical role and billing context of CPT code 95706, enabling alignment of clinical documentation and claims submission practices with payer requirements and facility workflows.
