CPT 95711: Unmonitored EEG with Video, 2–12 Hours

CPT code 95711 denotes an unmonitored electroencephalography (EEG) recording lasting between 2 and 12 hours, including video capture and a technical review and description by an EEG technologist. This extended ambulatory or hospital outpatient EEG fills a clinical role in evaluating intermittent or event-related neurologic symptoms that may not be captured in standard short EEGs. Nationally, utilization of extended EEG services affects neurology workflow, ambulatory monitoring capacity, and facility billing practices.

Key payers addressed in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise summary of what CPT code 95711 covers, typical sites of service, and the clinical context in which extended unmonitored EEG with video is employed. The publication outlines common billing modifiers and administrative considerations, benchmark topics, and any recent policy updates relevant to this service. It also situates the procedure within service lines for neurology and clinical neurophysiology, helping billing and compliance teams align documentation and coding with payer expectations.

This overview is intended for a national audience of clinicians, coding professionals, and revenue cycle staff seeking a clear, practical summary of CPT code 95711 and its operational and policy implications.

Billing Code Overview

CPT code 95711 describes an unmonitored electroencephalography (EEG) study lasting 2 to 12 hours. The service records the brain's electrical activity for an extended ambulatory or inpatient interval, includes a video recording, and requires review and a technical description by an EEG technologist.

Service Type: Extended, unmonitored EEG with video and technologist technical review

Typical Site of Service: Outpatient EEG laboratory or hospital outpatient department; may also be performed in an inpatient setting when ordered as an unmonitored extended recording

Clinical Context

A typical patient for 95711 is an adult or pediatric patient evaluated for intermittent or unexplained altered mental status, suspected seizure disorder, transient loss of consciousness, paroxysmal events, or monitoring of nocturnal events. In a common workflow the patient arrives to an outpatient EEG lab or hospital EEG unit where electrodes and a synchronized video camera are applied. The record is an unmonitored prolonged EEG lasting between 2 and 12 hours during which an EEG technologist performs periodic checks, documents technical events, and ensures video synchronization. No continuous physician monitoring or interpretation in real time is required during the acquisition. After completion, the technologist produces a technical description of the recording and the data are forwarded to a neurologist or epileptologist for formal interpretation and report. Typical sites of service include hospital outpatient EEG suites, ambulatory EEG centers, and outpatient neurology clinics with EEG capabilities. Common clinical scenarios include evaluation of new-onset paroxysmal events, assessment of suspected epilepsy or seizure recurrence, correlation of clinical events with EEG findings, and preoperative assessment when short-term ambulatory EEG is appropriate.

Coding Specifications

Modifier	Description	When to Use
`26`	Professional component	Use when a physician provides the interpretation/report separate from the technical recording.

Taxonomy Code	Specialty	Notes
`2084P0800X`	Neurology	Neurologists and epileptologists interpret EEG recordings and provide clinical reports.
`367H00000X`	Clinical Neurophysiology	Specialists in EEG and evoked potentials who often supervise and interpret prolonged EEGs.
`3356A0200X`	Electroencephalographic Technologist	EEG technologists perform electrode application, video-EEG acquisition, and technical descriptions.
`207RG0100X`	Pediatrics	Pediatric neurologists interpret EEGs for children when pediatric indications exist.

Related Diagnoses

ICD-10 Code	Description	Clinical Relevance
`G40.909`	Epilepsy, unspecified, not intractable, without status epilepticus	Common indication for prolonged EEG monitoring to detect epileptiform discharges and classify seizure type.
`G40.901`	Epilepsy, unspecified, intractable, without status epilepticus	Used when patients with refractory seizures require ambulatory/video-EEG correlation for management decisions.
`R56.9`	Unspecified convulsions	Frequent presenting symptom prompting prolonged EEG to determine if events are epileptic.
`G41.9`	Status epilepticus, unspecified	While `95711` is 2–12 hours and not for continuous urgent monitoring, it may be used to evaluate post-event EEG abnormalities in non-emergent settings.
`R55`	Syncope and collapse	Ambulatory EEG may be used when transient loss of consciousness events are suspected to be seizure-related rather than cardiac.
`F44.5`	Conversion disorder with seizures or convulsions	Prolonged video-EEG helps differentiate psychogenic non-epileptic seizures from epileptic seizures.
`G93.49`	Other encephalopathy	Altered mental status or episodic events in encephalopathy may prompt prolonged EEG recording to assess background and presence of epileptiform activity.

Related CPT Codes

CPT Code	Description	Relationship to This Procedure
`95951`	Video-electroencephalogram (V-EEG) monitoring for diagnostic purposes; extended monitoring for more than 48 hours up to 72 hours	Used when ambulatory or inpatient video-EEG monitoring is continued beyond the 12-hour maximum of `95711` and for prolonged diagnostic evaluation.
`95816`	Electroencephalogram (EEG); recording of eight to sixteen channels; awake and drowsy	Short routine EEG typically performed when a brief, standard study is sufficient prior to considering a prolonged ambulatory study like `95711`.
`95822`	Electroencephalogram (EEG); monitoring for seizure detection during sleep or wakefulness, routine with activation procedures	Used for routine monitored EEGs that differ from prolonged unmonitored ambulatory studies; may be ordered in conjunction or prior to `95711`.
`92651`	Audiometry, speech - pure tone, air only	Ancillary testing sometimes performed in comprehensive neurologic workups for syncope/dHIfferential assessment (example of other neurophysiologic tests commonly ordered alongside EEG assessments).
`97110`	Therapeutic exercises	Rehabilitation services that may follow neurologic diagnoses identified through EEG findings; represents downstream clinical workflow rather than the EEG itself.
