An electroencephalogram (EEG) is a recording of electrical current potentials spontaneously from nerve cells in the brain onto the skull. Variations in wave characteristics correlate with neurological conditions and are used to diagnose conditions.
EEGs can be transmitted by telephone in which electrical brain activity is recorded and transmitted to an off-site center for interpretation and report or by radio or cable in the diagnosis of complex seizure variants which require inpatient monitoring, but do not require the patient to be in bed.
EEGs can be recorded by 24-hour ambulatory cassette. Twenty-four-hour ambulatory cassette-recorded EEGs offer the ability to record the EEG on a long-term, outpatient basis. Electrodes for at least 4 recording channels are secured on the patient. The cassette recorder is attached to the patient’s waist or on a shoulder harness. Recorded electrical activity is analyzed by playback through an audio amplifier system and video monitor.
Electroencephalographic video monitoring is the simultaneous recording of the EEG and video monitoring of patient behavior. This allows for the correlation of ictal and interictal electrical events with demonstrated or recorded seizure symptomology. This type of monitoring allows the patient’s face or entire body to be displayed on a video screen.
The objective of this review is to determine whether the use of EEG can improve the net health outcome of patients in a variety of neurological conditions and settings.
Transmission of the EEG by telephone, radio, or cable is considered medically necessary when the closest medical facilities are located in remote areas with untrained EEG interpreters for patients with the following indications:
· Altered consciousness, such as stuporous, semi-comatose, or comatose states;
· Atypical seizure variants in patients experiencing bizarre, distressing symptoms as seen with “spike and wave stupor” or other forms of seizure disorders;
· Head injury, where a subdural hematoma may be identified; or
· Differentiation of complicated migraine with epilepsy-like symptoms (e.g., auras, alterations in level of consciousness) from true seizure disorders.
Radio and cable telemetry of the EEG is considered medically necessary with prior approval for:
· EEG recording during provocation testing (e.g., withdrawal of anticonvulsant medications), which can be safely undertaken only in the immediate proximity of emergency medical personnel and technology; and
· EEG recording attempting to localize the seizure focus prior to surgery when ambulation is desirable (e.g., when seizures are triggered by specific environmental stimuli or daily events).
Telephone transmission of the EEG to determine electrocerebral silence, i.e., brain death, is considered investigational.
Twenty-four-hour ambulatory cassette-recorded EEGs are medically necessary with prior approval in the following circumstances:
· When used in conjunction with ambulatory electrocardiogram (ECG) recordings for seizures suspected to be of cardiogenic origin;
· When used in conjunction with electrooculogram (EOG) and electromyogram (EMG) recordings for suspected seizures of sleep disturbances;
· When used for quantification of seizures in patients who experience frequent absence seizures; and
· When used in documenting seizures that are precipitated by naturally occurring cyclic events or environmental stimuli that are not reproducible in the hospital or clinical setting.
Twenty-four-hour ambulatory cassette-recorded EEGs are considered investigational in the following circumstances:
· For the study of neonates or unattended, noncooperative patients;
· In localization of seizure focus/foci when the seizure symptoms and/or other EEG recordings indicate the presence of bilateral foci or rapid generalization; and
· For final evaluation of patients who are being considered as candidates for resective surgery.
Video/EEG monitoring is considered medically necessary with prior approval when used to confirm the diagnosis of cases of complex seizures where treatment is defined by the seizure type. EEG video monitoring is useful for patients where a diagnosis could not be made on the basis of a neurological examination, routine EEG reporting, and ambulatory cassette EEG monitoring.

A seizure is a transient episode of symptoms and/or signs due to abnormal excessive or synchronous neuronal activity in the brain. A seizure does not necessarily mean that a person has epilepsy unless criteria for a diagnosis of epilepsy are met. There are numerous conditions that can be associated with convulsive events that can resemble seizures/epilepsy, these should be carefully excluded (Epilepsy Foundation, 2018). Epilepsy is diagnosed when: at least two unprovoked (or reflex) seizures occur more than 24 hours apart, or one unprovoked (or reflex) seizure with a probability of further seizures occurring over the next ten years or a diagnosis of an epilepsy syndrome (Schachter, 2018).
Epilepsy is a disorder caused by the excessive and intense activity of certain neurons in the brain. The seizures caused by this activity can last for several minutes and, depending on the region of the brain affected, they can bring about fainting, involuntary and violent shaking, or brief episodes of unconsciousness. Epilepsy can have a genetic origin or result from brain damage, and for some individuals, its underlying cause may not be determined. The seizures that result from this abnormal neuron activity in the brain may be caused by neurological imbalances, or medical conditions (i.e., drug or alcohol withdrawal). Therefore, seizure type and precipitating causes should be identified to determine the best course of treatment.
The diagnosis of epilepsy can be complicated, and it is not unusual to have a misdiagnosis. Diagnosing epileptic seizures is made by analyzing the patient’s clinical history, laboratory results, and an electroencephalogram (EEG). An EEG is an important diagnostic test in assessing a patient with potential epilepsy. It can support the diagnosis of epilepsy and also assist in classifying the underlying epileptic syndrome. An EEG measures the electrical activity of the brain (i.e., brainwaves) using recording equipment attached to the scalp by electrodes. The EEG is used in the evaluation of brain disorders, and most commonly used to show the type and location of the activity in the brain during a seizure. It may also be used to evaluate problems associated with brain function such as confusion and long-term difficulties with thinking or memory.
An EEG is obtained to document the presence and frequency of abnormal neuron activity. In most cases, a routine EEG can identify brain activity specific to seizures. The EEG can provide support for the diagnosis of epilepsy and also assists in classifying the underlying epileptic syndrome. However, there are several reasons why in some cases a routine EEG alone cannot be used to make or refute a specific diagnosis of epilepsy (Moeller, et al., 2018):
• Most EEG patterns can be caused by a wide variety of different neurologic diseases.
• Many diseases can cause more than one type of EEG pattern.
• Intermittent EEG changes, including interictal epileptiform discharges, can be infrequent and may not appear during the relatively brief period of routine EEG recording.
• The EEG can be abnormal in some persons with no other evidence of disease.
• Not all cases of brain disease are associated with an EEG abnormality, particularly if the pathology is small, chronic, or located deep in the brain.
For some individuals diagnosed with epilepsy, the EEG may remain normal. Spike discharges may not be captured on an EEG because their occurrence is rare or their site of origin is very small or within an occult area of the cortex. Spike activity can also be affected by antiepileptic medication (Blume, 2005; Aminoff, 2003). A normal patient may also show unusual brain activity on an EEG and be incorrectly diagnosed. When a definitive diagnosis cannot be made from a clinical examination and a resting EEG, additional testing may be necessary (e.g., ambulatory EEG, video EEG). A prolonged 24-hour ambulatory EEG in the outpatient/home setting may be used to differentiate between the presence of epileptic, non-epileptic or psychogenic seizure disorders. The focus of this Coverage Policy is ambulatory EEG.
Ambulatory Electroencephalography (EEG)
Ambulatory or 24-hour EEG monitoring is performed by a recorder that continuously records brain wave patterns during a patient's routine daily activities and sleep up to 72 hours. An ambulatory EEG can be done with or without video recording. The monitoring equipment includes an electrode set, preamplifiers, and a recorder. The electrodes attach to the scalp, and the leads are connected to a recorder, usually worn on a belt. Ambulatory EEG allows patients to be evaluated in their natural environments, with exposure to potential stressors and other seizure triggers.
Prolonged continuous ambulatory EEG recording throughout one or more complete natural sleep/wake cycles increases the likelihood of documenting an ictal episode. The most helpful finding on EEG is interictal epileptiform discharges (IEDs). Identification of interictal epileptiform discharges, which are EEG patterns believed to be associated with a relatively high risk for having seizures, have been reported as occurring in 95% of epilepsy patients within 48 hours of monitoring (Tatum, et al., 2018; Seneviratne, et al., 2013; Faulkner, et al., 2012). Routine EEG has low sensitivity in epilepsy ranging from 25%–56%, with a specificity of 78%–98% (Smith, 2005). Serial routine EEGs, studies performed a short time after an epileptic seizure as well as sleepdeprived EEG studies increase the overall diagnostic yield. However, those methods are usually considered inferior to long-term EEG monitoring, where the duration of recording is measured in hours or days (Keezer, et al., 2016).
Ambulatory EEG recordings can be utilized in the evaluation and differential diagnosis of non-epileptic seizures if these episodes are unable to be diagnosed by conventional studies. There are two categories of non-epileptic seizures: pathophysiological events and non-epileptic psychopathological/psychiatric events. Pathophysiological events include: autonomic disorders, cardiac arrhythmias, drug toxicity, metabolic disorders, migraines, orthostatic hypotension, sleep disorders, valvular heart disease, vasovagal syncope and vestibular disorders. Non-epileptic psychopathological/psychiatric events include: anxiety, depression, panic attacks, psychogenic seizures and psychosis (Mesraoua, 2012).
Syncope, for example, shares some clinical characteristics with seizures which may lead to diagnostic confusion. Seizures and syncope may also coexist in a given individual. In general, a syncopal episode or temporary loss of consciousness may be considered unrelated to epilepsy if any of the following features are present:
• prodromal symptoms that on other occasions have been abolished by sitting or lying down
• sweating before the episode
• prolonged standing that appeared to precipitate the temporary loss of consciousness
• pallor during the episode
Sleep and sleep stage have a significant impact on the incidence and frequency of both seizures and epileptiform discharges that occur in between seizures. Generally, non-rapid eye movement (NREM) sleep facilitates interictal epileptiform discharges (IED) and seizures, while rapid eye movement (REM) sleep tends to inhibit seizures. Prolonged outpatient ambulatory, inpatient video-EEG recordings, or overnight video-EEG polysomnography, are of higher yield in detecting IEDs and capturing seizures in the sleep-related focal epilepsies (St Louis et al., 2018).
Literature Review: The diagnostic accuracy of ambulatory EEG has not been well studied. Authors have reported through several retrospective studies with patient populations ranging from 46–344, the value of adding ambulatory EEG to standard EEG recording data in confirming the presence or absence of epileptic conditions. In a prospective study (n=72) by Keezer et al. (2016), the sensitivity of ambulatory EEG was reported to be 2.23 times greater than that of routine EEG (p<0.0001). Ambulatory EEG results have been reported to change clinical management in up to 51% of patients. The median duration of recording was 1.4 days (Faulkner, et al., 2012). Prolonged ambulatory EEG has been found to have a higher probability of recording an epileptic event relative to sleep-deprived EEG (15.2% versus 0%, respectively; p=0.01) (Liporace, et al., 1998).The published peer-reviewed medical literature contains some evidence primarily in the form of case series to support the use of ambulatory EEG. While the supporting evidence is not robust, the use of ambulatory EEG monitoring has become a standard of care within the armamentarium of diagnostic evaluations of epilepsy versus a nonepileptic syndrome for a subset of individuals.
N/A
Evidence reviews assess whether a medical test is clinically useful. A useful test provides information to make a clinical management decision that improves the net health outcome. That is, the balance of benefits and harms is better when the test is used to manage the condition than when another test or no test is used to manage the condition.
The first step in assessing a medical test is to formulate the clinical context and purpose of the test. The test must be technically reliable, clinically valid, and clinically useful for that purpose. Evidence reviews assess the evidence on whether a test is clinically valid and clinically useful. Technical reliability is outside the scope of these reviews, and credible information on technical reliability is available from other sources.

Population Reference No. 2
Ambulatory or 24-hour electroencephalographic (EEG) monitoring is accomplished by a cassette recorder that continuously records brain wave patterns during sleep and 24 hours of a patient's routine daily activities. The monitoring equipment consists of preamplifiers, an electrode set, and a cassette recorder. The electrodes attach to the scalp, and their leads are connected to a recorder.
Ambulatory EEG monitoring is a diagnostic procedure for patients in whom a seizure diathesis is suspected but not defined by history, physical or resting EEG.Ambulatory EEG should always be preceded by a resting EEG.
Twenty-four hour ambulatory cassette-recorded EEGs are medically necessary with prior approval in the following circumstances:
· When used in conjunction with ambulatory electrocardiogram (ECG) recordings for seizures suspected to be of cardiogenic origin;
· When used in conjunction with electrooculogram (EOG) and electromyogram (EMG) recordings for suspected seizures of sleep disturbances;
· When used for quantification of seizures in patients who experience frequent absence seizures; and
· When used in documenting seizures that are precipitated by naturally occurring cyclic events or environmental stimuli that are not reproducible in the hospital or clinic setting.
Twenty-four hour ambulatory cassette-recorded EEGs are considered investigational in the following circumstances:
· For the study of neonates or unattended, noncooperative patients;
· In localization of seizure focus/foci when the seizure symptoms and/or other EEG recordings indicate the presence of bilateral foci or rapid generalization; and
· For final evaluation of patients who are being considered as candidates for resective surgery.

Population Reference No. 3
Video/EEG monitoring is considered medically necessary with prior approval when used to confirm the diagnosis of cases of complex seizures where treatment is defined by the seizure type. EEG video monitoring is useful for patients where a diagnosis could not be made on the basis of a neurological examination, routine EEG reporting, and ambulatory cassette EEG monitoring.
The majority of the body of evidence published in the peer-reviewed literature consists of retrospective and prospective cohort studies, retrospective studies, and, retrospective reviews. Sample size ranged from 29 to >400 and the mean age ranged from 35 to 52 years. Indications for referral included seizures requiring diagnostic clarification and presurgical evaluation. The duration of seizures across a lifetime was noted in 3 studies, with median/mean values of approximately 15 years with wide ranges. One study included patients that had a new-onset seizure. The studies reported that VEEG altered the diagnosis for some patients. The studies reported changes in antiepileptic drugs (AEDs) as a result of VEEG. The available evidence shows that video electroencephalogram (VEEG) monitoring can provide valuable information to guide the diagnosis and treatment of patients who report seizures when a standard electroencephalogram (EEG) has not provided a clear diagnosis and in patients with refractory epilepsy. Studies have shown that VEEG changed the diagnosis from epileptic seizures to psychogenic non-epileptic seizures (PNES), and the vice versa. In addition, some of the studies reported elimination or reductions in medication after diagnostic changes.

American Board of Internal Medicine’s (ABIM) Foundation Choosing Wisely® Initiative (2017): The American Academy of Neurology (AAN) (2013) recommended that EEG not be performed for headaches. According to the AAN, an EEG offers no advantage over clinical evaluation in diagnosing headaches, nor does it improve outcomes.
American Clinical Neurophysiology Society (ACNS): According to the ACNS, indications for long term EEG monitoring (e.g., ambulatory EEG) included the following:
1. Identification of epileptic paroxysmal electrographic and/or behavioral abnormalities. These included epileptic seizures, overt and subclinical, and documentation of interictal epileptiform discharges.
2. Verification of the epileptic nature of the new “spells” in a patient with previously documented and controlled seizures.
3. Classification of clinical seizure type(s) in a patient with documented but poorly characterized epilepsy
The ACNS further stated that EEG and/or behavioral abnormalities may assist in the differential diagnosis between epileptic disorders and conditions associated with intermittent symptoms due to non-epileptic mechanisms (e.g., syncope, narcolepsy, other sleep disturbances, psychogenic seizures) (ACNS, 2008).
