CPT 95725: Long-duration EEG Review for Spike and Seizure Detection

CPT code 95725 represents the professional review, analysis, interpretation and reporting of recorded events for spike and seizure detection from a continuous electroencephalography (EEG) study lasting more than 84 hours without video. This code matters nationally because extended-duration EEG monitoring is a critical diagnostic tool for complex seizure disorders, status epilepticus assessment, and pre-surgical evaluation, and accurate coding affects clinical documentation and payment across major payers.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical service that CPT code 95725 represents, the typical care setting where the service occurs, and the operational implications for billing and reporting. The publication outlines national benchmarks and coverage context where available, highlights common modifiers associated with EEG services, and summarizes the clinical context in which extended EEG monitoring is used. Data not available in the input is noted where applicable. The content provides actionable clarity on coding terminology and service definition for clinicians, billing staff, and policy analysts working with prolonged EEG interpretation.

Billing Code Overview

CPT code 95725 describes a physician or qualified healthcare professional review and analysis of recorded events for spike and seizure detection from a continuous electroencephalography (EEG) study that continues greater than 84 hours without video recording. The provider interprets the EEG findings and prepares a formal report.

Service type: Long-duration continuous EEG interpretation and event review
Typical site of service: Inpatient or outpatient facility settings where extended EEG monitoring is performed (for example, hospital EEG monitoring units or specialized neurology clinics)

Clinical Context

A 28-year-old patient with a history of refractory focal epilepsy is admitted for extended electroencephalographic monitoring to characterize seizure frequency and morphology. Continuous scalp EEG electrodes are placed and recorded for over 84 hours without synchronized video capture to evaluate electrographic seizure events and interictal epileptiform discharges. A neurologist or other qualified health care professional reviews the continuous EEG recording, performs spike and seizure detection analysis, documents the timing and characteristics of electrographic events, and generates a formal interpretation and report. Typical workflow steps: patient admission and electrode application in an inpatient neurology unit or epilepsy monitoring unit, continuous EEG acquisition for >84 hours without video, periodic review of recorded data by the interpreting clinician, formal interpretation and report generation, and communication of findings to the treating team for medication or surgical planning.

CPT Code	Description	Relationship to This Procedure
`95726`	A physician or other qualified health care professional reviews recorded events and analyzes spike and seizure detection of a continuous EEG: complete study continues greater than 84 hours of EEG recording with synchronized video	Performed when prolonged EEG monitoring includes synchronized video; complements `95725` when video is obtained.
`95720`	Continuous EEG monitoring; review and interpretation of recorded events for less than 24 hours of recording	Performed for shorter-duration monitoring when clinical needs do not require >84 hours.
`95722`	Continuous EEG monitoring; review and interpretation of recorded events for 24-48 hours of recording	Used for intermediate-duration monitoring prior to escalation to >84-hour studies.
`95723`	Continuous EEG monitoring; review and interpretation of recorded events for 48-72 hours of recording	Used when clinical indication requires multi-day monitoring but not yet >84 hours.
`95951`	Video-electroencephalographic monitoring, with EEG and video, typically used for infants and neonates (limited)	Related when video-EEG monitoring is required for clinical correlation; not used for EEG-only studies.
