Electroencephalographic (EEG) Video Monitoring — CPB 0322 | AETNA Coverage Update

TL;DR: Aetna, a CVS Health company, modified CPB 0322 governing EEG video monitoring coverage, effective January 11, 2026. If your team bills CPT 95700, 95711–95716, 95718–95726, or related EEG codes for Aetna members, this coverage policy update sets tighter medical necessity criteria and explicit data requirements you need to document before claims go out.

Aetna EEG Video Monitoring Coverage Criteria and Medical Necessity Requirements 2026

The Aetna EEG video monitoring coverage policy under CPB 0322 Aetna system covers attended EEG video monitoring performed in a healthcare facility — but only when specific conditions are met. The policy draws a hard line: diagnosis must still be uncertain after a neurological examination and standard EEG study, both within the past 90 days. Non-neurological causes — syncope, cardiac arrhythmias — must already be ruled out.

Five indications qualify for medical necessity coverage:

One important carve-out: the requirement for a prior standard EEG and neurologic exam is waived when video EEG is performed in an intensive care unit (ICU). If your team bills CPT 95700 for ICU-based EEG setup, you don't need to document those prerequisites — but you still need to document the ICU setting.

The policy also covers attended EEG video monitoring for seizure focus identification and localization in patients with intractable epilepsy who are surgical candidates. Cross-reference Aetna CPB 0394 (Epilepsy Surgery) when billing this indication.

Prolonged monitoring — defined as more than seven days — clears the medical necessity bar only in three situations: events are so infrequent that a standard week would likely miss them; an adverse event (postictal psychosis, falls, respiratory failure, status epilepticus) requires extended inpatient care; or medication adjustments require ongoing monitoring that can't be done safely outpatient. Document which of these applies, explicitly, in the record.

Aetna's updated policy also sets explicit technical requirements for what counts as valid video EEG (VEEG) data. The recording must be continuous and synchronized — both EEG and video together, in real time — with secure data storage for at least 24 hours. Events must be annotated with timestamps and written descriptions. Trained observers (EEG technologists or equivalent) must provide supervision. This is a documentation requirement that will drive claim denial if your facility's records don't reflect it.

Once the diagnosis and seizure type are established, continued video EEG monitoring — for example, to monitor response to therapy or titrate medication in older children and adults — is not considered medically necessary. Aetna's view is that standard EEG or ambulatory EEG is sufficient for that ongoing work. If you've been billing CPT 95715 or 95716 for routine medication titration monitoring in established adult epilepsy patients, those claims are now at risk.

Prior authorization requirements under Aetna vary by plan. Given the specificity of these criteria, assume prior auth is required for inpatient video EEG monitoring and confirm with the member's specific plan before scheduling.

Aetna EEG Video Monitoring Exclusions and Non-Covered Indications

Aetna's coverage policy is blunt about what it won't pay for. EEG video monitoring for driving clearance is not considered medically necessary treatment of disease. Full stop.

Beyond that, Aetna classifies video EEG as experimental, investigational, or unproven for a long list of indications. These include:

That last exclusion deserves attention. Drug effectiveness assessment in epilepsy is explicitly excluded. Aetna's language clarifies this applies to EEG video monitoring used to assess treatment effectiveness — not to the covered indication of establishing an initial diagnosis or evaluating response to treatment in young children or non-communicative patients.

If a claim goes out with epilepsy codes from G40.001–G40.919 or G40.A01–G40.B19 and the documentation reads as "monitor response to antiepileptic therapy" in an adult, expect a denial. The clinical framing in the record has to match a covered indication — not just any interaction with epilepsy treatment.

Aetna EEG Video Monitoring Billing Guidelines and Action Items 2026

EEG video monitoring billing under CPB 0322 has always required careful documentation. This January 11, 2026 update raises the bar. Here's what to do now.

Copy Action Items

If your facility runs a high-volume EEG monitoring program or an epilepsy monitoring unit, talk to your compliance officer before the effective date of January 11, 2026. The combination of the 90-day prerequisite rule, the new VEEG data documentation requirements, and the explicit exclusions for ongoing monitoring creates meaningful reimbursement exposure.
