Coverage Criteria for EEG, VEEG and QEEG

Quantitative EEG (QEEG) - Covered Indications

QEEG is considered medically necessary when ALL of the following apply:

QEEG required conditions: a) Is used as an adjunct to and in combination with a traditional EEG; b) Is performed by a specialist trained in its use; c) Is used only for specified indications: (i) Epilepsy — when surface or long-term EEG is inconclusive; when ambulatory recording is needed to facilitate subsequent visual interpretation; for topographic voltage and dipole analysis in pre-surgical candidates with intractable epilepsy; (ii) Cerebrovascular disease, dementia, or encephalopathy when imaging and routine EEG are inconclusive; (iii) Operating room monitoring for early detection of acute intracranial complication during surgery; (iv) ICU monitoring for detection of nonconvulsive seizures in high-risk ICU patients.

Epilepsy sub-indications include inconclusive surface/long-term EEG, ambulatory recording to aid visual interpretation, and topographic/dipole analysis for pre-surgical candidates.

QEEG - Exclusions (Not Medically Necessary)

QEEG exclusions: QEEG is not medically necessary for conditions including, but not limited to: alcoholism; attention-deficit/hyperactivity disorders (ADD/ADHD); depression; drug/substance abuse; mild or moderate head injury; learning disability; schizophrenia; and any other condition or indication not explicitly listed as supported.

Exclusion list is non-exhaustive as stated in the policy.

General coverage for EEG/VEEG

Covered when documentation supports the specific EEG/VEEG service and relevant clinical indication codes:

Basic EEG/VEEG coverage logic: EEG/VEEG services (for example CPT codes 95700 and 95711-95726, and physician review/interpretation codes 95718-95726) are described with specific durations and monitoring levels; coverage requires documentation consistent with those code definitions (including duration of recording, monitoring intensity, and physician review/interpretation) and clinical indication codes that support medical necessity.

Detailed medical necessity criteria and code-specific documentation requirements are described elsewhere in the policy; providers should document duration, monitoring level, and clinical justification to match the selected CPT code.

Quantitative electroencephalography (QEEG) is not considered medically necessary when used to evaluate conditions such as alcoholism, attention-deficit/hyperactivity disorder (ADD/ADHD), depression, drug/substance abuse, mild or moderate head injury, learning disability, and schizophrenia. The policy explicitly lists these diagnoses as exclusions and states that QEEG is not medically necessary for these and other similar non-indicated conditions.

The policy designates topographic brain mapping (HCPCS S8040) and ambulatory EEG (without or with video monitoring/recording) as Not Covered. Providers should not bill for S8040 or ambulatory EEG services under this coverage statement.

Beyond the named exclusions, QEEG is considered not medically necessary for any other condition or indication not explicitly listed. The policy provides an illustrative, non‑exhaustive exclusion list (including substance use disorders, many psychiatric and developmental disorders, and certain concussion codes) to indicate that QEEG is not appropriate as a general diagnostic tool outside the specified clinical indications.

Use of EEG or VEEG is not supported when the primary justification is one of the ICD‑10 diagnoses enumerated as not supporting medical necessity. Examples include multiple substance‑abuse codes (e.g., F10.10‑F10.99), schizophrenia and other major psychiatric disorder codes (e.g., F20.x, F32.x), ADHD (F90.0‑F90.9), certain concussion codes without loss of consciousness, obstructive sleep apnea (G47.33), amyotrophic lateral sclerosis (G12.21), chronic fatigue and coma codes, and headache codes. Claims based primarily on these diagnoses may be denied as not meeting medical necessity for EEG/VEEG.

Provider Actions, Prior Authorization, and Documentation

Prior Authorization

Prior Authorization Required

Prior authorization is required for certain EEG and VEEG services. Submit a prior authorization request demonstrating medical necessity before performing extended or monitored EEG/VEEG when plan documents or the Priority Health Provider Manual indicate prior authorization is required.

Prior authorization required when indicated by plan or Provider Manual
Failure to obtain prior authorization may result in claim denial or delay

Prior Authorization

Prior Authorization for Extended/Advanced EEG/VEEG Services

Certain extended and advanced EEG/VEEG services (continuous monitoring, video with extended duration, physician review of long-term recordings) require prior authorization and appropriate documentation to justify CPT code selection and duration of monitoring.

CPT codes: 95700, 95711-95716, 95718, 95720, 95722, 95724 (see coding section)
Include requested monitoring duration (hours), level of monitoring (unmonitored, intermittent, continuous real-time), and setting (home, freestanding center, hospital)

Definitions and Key Terms

inv-25: Video electroencephalographic (VEEG) monitoring — definition and use

DefinitionVideo electroencephalographic (VEEG) monitoring is EEG enhanced by synchronized video recording to correlate electrophysiologic changes with observed behaviors over a prolonged period (typically several days)

Primary usesConfirm suspected seizure activity, detect and classify seizure types and focus, adjust antiseizure medications, and assist in pre-surgical planning

SettingsMay be performed in home, freestanding center, or hospital-based settings; certain higher-risk situations (medication withdrawal, preoperative invasive monitoring) should occur in hospital-based settings for safety

Relation to documentationCoverage requires documentation consistent with the selected CPT code (duration and monitoring level) and the clinical indication

inv-26: Quantitative EEG (QEEG) — definition and examples of analyses

Background and Rationale

Electroencephalography (EEG) records the brain’s electrical activity via scalp electrodes using standard placement systems; when combined with synchronized video, it is termed video EEG (VEEG). VEEG permits correlation of electrophysiologic events with observed behaviors over prolonged monitoring and is useful to confirm suspected seizures, classify seizure types, guide medication management, and support pre‑surgical evaluation. Continuous EEG/VEEG services are described by specific CPT codes that specify technician setup, monitoring level (unmonitored, intermittent, continuous real‑time), and duration (for example, 2–12 hours, 12–26 hours, >36 to 60 hours, >60 to 84 hours, and >84 hours), with physician review/interpretation codes defined for analysis and reporting.
