CPT 95719: Continuous EEG Interpretation for Spike and Seizure Detection

CPT code 95719 covers physician or qualified healthcare professional review and interpretation of continuous electroencephalography (EEG) recordings for spike and seizure detection when no video is obtained, reported for each increment greater than 12 hours up to 26 hours. This service is an important element of neurological monitoring for patients with suspected or known seizure disorders, status epilepticus, or other conditions requiring extended EEG surveillance. Nationally, accurate coding and documentation of prolonged EEG interpretation supports care coordination, clinical decision-making, and appropriate payment for extended monitoring.

Key payers included in the analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical context of prolonged EEG interpretation, typical sites of service, and the reporting interval specifics for 95719. The publication also outlines common modifiers encountered in claims (input provided) and notes where input data is incomplete: associated taxonomies, ICD-10 diagnoses, related codes, and service line data are not available in the input.

This piece is intended to inform billing, coding, and clinical teams about the clinical role and billing construct of CPT code 95719, and to provide clarity on how the code is described and used across typical payer settings.

Billing Code Overview

CPT code 95719 describes interpretation of recorded events and analysis of spike and seizure detection from a continuous electroencephalography (EEG) study where no video is obtained. The provider reviews the EEG recording, interprets findings, and prepares a report for each increment of greater than 12 hours up to 26 hours of EEG recording.

Service type: EEG interpretation and spike/seizure detection analysis over prolonged continuous recording
Typical site of service: Inpatient or outpatient settings where continuous EEG monitoring is performed (hospital EEG monitoring units, inpatient wards, or ambulatory EEG services)

Clinical Context

A 28-year-old patient admitted to an inpatient neurology unit is undergoing continuous electroencephalographic monitoring for evaluation of suspected nonconvulsive seizures after a witnessed generalized tonic-clonic seizure in the emergency department. The hospital technologist performs continuous scalp EEG recording without video for prolonged monitoring. A board-certified neurologist or qualified healthcare professional reviews the recorded EEG data off-line, analyzes spike activity and seizure-detection trends, interprets the findings, and prepares a formal report covering a continuous recording interval greater than 12 hours but not exceeding 26 hours. Typical workflow: order placed by neurology team -> EEG technologist initiates continuous EEG recording -> data stored on the monitoring system -> neurologist/QHCP reviews recorded events and spike/seizure detections (often in segments) -> interpretation and report generated in the electronic health record -> billing for 95719 per qualifying 12+ hour increment. Typical site of service is an inpatient hospital or observation unit; the service type is physician interpretation of prolonged continuous EEG monitoring without video (clinical neurophysiology consultative/interpretive service).

`26`	Professional component	Use when billing only the professional interpretation component separate from technical recording services.

Taxonomy Code	Specialty	Notes
2084P0800X	Neurology	Neurologists, especially clinical neurophysiologists, commonly interpret prolonged EEGs.
2084N0400X	Pediatric Neurology	Pediatric neurologists interpret prolonged EEGs in children when performed without video.
103T00000X	Nurse Practitioner	Neurology-focused NPs may review and co-sign monitoring under supervision depending on state rules.
207RH0000X	Clinical Neurophysiology	Specialists in clinical neurophysiology or EEG interpretation perform and report prolonged EEG studies.
207K00000X	Physician Assistant	PAs working in neurology may assist with monitoring workflows and documentation under supervising physician.

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 seizure activity.
`G40.901`	Epilepsy, unspecified, intractable, without status epilepticus	Used when seizures are refractory and prolonged EEG is needed for characterization.
`G41.9`	Status epilepticus, unspecified	Prolonged EEG monitoring helps detect ongoing nonconvulsive status epilepticus.
`R56.9`	Unspecified convulsions	Diagnostic monitoring after an unclassified convulsive event.
`F44.5`	Conversion disorder with seizures or convulsions	EEG interpretation used to distinguish epileptic from non-epileptic events.
`G31.84`	Mild cognitive impairment, so stated	Prolonged EEG may be used when transient events or seizure-related cognitive changes are suspected.
`I63.9`	Cerebral infarction, unspecified	Stroke patients can develop seizures; continuous EEG may be used for detection.
`R27.9`	Unspecified lack of coordination	When brief transient events are suspected to be seizures, prolonged EEG can assist diagnosis.

Related CPT Codes

CPT Code	Description	Relationship to This Procedure
`95716`	Continuous electroencephalography (EEG) recording; analysis and interpretation for up to 12 hours, without video	Performed for shorter monitoring intervals; `95716` is billed when total EEG recording is 12 hours or less before `95719` thresholds apply.
`95720`	Continuous electroencephalography (EEG) recording; analysis and interpretation for each additional increment of greater than 12 hours up to 26 hours (list separately in addition to primary)	Billed in sequence when monitoring exceeds the initial `95719` interval and additional qualifying increments are present.
`95816`	Electroencephalogram (EEG); long-term video monitoring, any duration, technical component only	Video-EEG counterparts that include video capture; contrasts with `95719` which specifies no video.
`95951`	Monitoring for seizure detection, continuous inpatient telemetry (EEG/ECG), analysis and interpretation, first 24 hours	Alternative monitoring codes used in some telemetry contexts; may be part of the broader seizure monitoring workflow.
`99223`	Initial hospital care, typically 70 minutes or more	An E/M code that may be reported if a significant separate inpatient evaluation is performed on the same day as the EEG interpretation; modifier `25` may be required.
