Important: Aetna Left the ACA Marketplace in January 2026

If your Aetna plan came from the Health Insurance Marketplace, it ended on December 31, 2025. CVS Health withdrew Aetna from the ACA individual market for the 2026 plan year, exiting all seventeen states where it sold those plans. Around one million people nationally had to find new coverage.

Check this before you call any treatment program. A facility that verifies a terminated policy will tell you that you have no coverage, which is not the same thing as being uninsurable — you may well have replacement coverage available.

Aetna coverage that continues normally: employer-sponsored group plans, Aetna Medicare Advantage, Medicaid plans where Aetna holds the state contract, and self-funded employer plans that use the Aetna network through Aetna Signature Administrators.

Losing coverage is a qualifying life event, so a replacement plan can usually be arranged outside open enrollment. Treatment can still begin while that is in progress.

Does Aetna Cover Rehab?

Yes. Under the federal Mental Health Parity and Addiction Equity Act, Aetna must apply the same standards to behavioral-health benefits that it applies to medical and surgical benefits — the same deductibles, the same visit limits, and the same kind of medical-necessity review. In practice that means addiction and mental-health treatment is covered when it is clinically necessary, judged against criteria such as those published by the American Society of Addiction Medicine.

Aetna is the brand name for products and services provided by Aetna Life Insurance Company and its affiliates, and is part of the CVS Health family of companies. Virtual behavioral health is delivered through Aetna telehealth, CVS Virtual Care and Teladoc Health.

What varies is not whether you are covered but how much you pay and which programs you can use — and that comes down to your plan type, your deductible, and whether the program is in network.

How to Find Rehab Centers That Accept Aetna

Three things worth establishing before you commit to a program:

• Is your plan active? Particularly important if it came from the Marketplace — see above.
• Does the program participate with your specific plan? Not just “with Aetna”. Networks differ between commercial, Medicare Advantage and Signature Administrators plans.
• What will you actually owe? Deductible, coinsurance, and out-of-pocket maximum, for the level of care being recommended rather than in general.

A benefits verification answers all three in about fifteen minutes. Start a free verification or call 866-644-7911.

Aetna Rehab Coverage by Level of Care

Medical Detox

Typically 3–10 days of medically supervised withdrawal management. Covered when withdrawal presents a medical risk — which for alcohol and benzodiazepines it frequently does.

Inpatient Hospitalization

Acute psychiatric or medical stabilization in a hospital setting, for the most severe presentations.

Residential Rehab

ASAM Level 3.5 or 3.7 clinical care with 24-hour support. Authorization normally comes in increments with continued-stay reviews rather than as a single approval for the whole admission.

Partial Hospitalization (PHP)

Around 5–6 hours a day, five days a week, living at home or in supported housing. Commonly a step down from residential.

Intensive Outpatient (IOP)

Around 3 hours a day, 3–5 days a week, designed to fit around work or school.

Standard Outpatient

Weekly individual therapy, group therapy or psychiatry. Usually the longest phase of treatment and the one most people underuse.

Medication-Assisted Treatment (MAT)

Buprenorphine, naltrexone and methadone for opioid use disorder, and naltrexone or acamprosate for alcohol use disorder. Covered as a medical benefit, a pharmacy benefit, or both, depending on the plan.

Telehealth

Virtual behavioral health, including through CVS Virtual Care and Teladoc Health. Genuinely useful where the nearest in-person program is an hour away.

Aetna Rehab Coverage by Substance

Aetna covers treatment for substance use disorders recognized in the DSM-5. The level of care that gets authorized varies by substance, mostly because withdrawal risk does:

• Aetna alcohol rehab — medical detox, residential and outpatient care, plus naltrexone, acamprosate and disulfiram. Alcohol withdrawal can be fatal, which makes detox straightforward to authorize.
• Aetna opioid rehab — detox, residential and medication-assisted treatment with buprenorphine, methadone or naltrexone. Medication is the standard of care, not an alternative to it.
• Aetna benzodiazepine detox — slow medically supervised taper, often longer than standard detox because abrupt cessation risks seizures.
• Stimulant use — methamphetamine and cocaine — no approved medication exists, so coverage centers on residential or PHP and IOP with behavioral therapy and dual-diagnosis support.
• Prescription medication — including ADHD stimulants, sleep medication and prescribed opioids. Dependence that began with a legitimate prescription is covered on the same terms as any other.
• Aetna dual diagnosis rehab — integrated treatment where a mental-health condition and a substance use disorder occur together, which is the majority of cases.

Aetna Plan Types and Rehab Coverage

Aetna organizes its commercial plans into families, and the name on your card maps to a real difference in what you can use:

• Aetna Standard Family — the core plans, ranging from Open Choice® PPO, which requires no referrals and no PCP selection, through to HMO and exclusive provider plans.
• Aetna Open Access® Family — encourages but does not require choosing a PCP, and members go directly to network specialists without a referral. Includes Open Access Managed Choice® (POS), Open Access Elect Choice (EPO) and Open Access HMO.
• Aetna Select℠ — PCP referral generally required, and outside emergency or out-of-area urgent care, benefits are not covered out of network.
• Aetna HealthFund® — a deductible plan paired with an employer health fund, combining referral-free network access with the ability to seek out-of-network care.
• Aetna Medicare℠ — HMO, PPO and the Aetna Medicare Open℠ private-fee-for-service plan.

In Washington, the product referred to as HMO is called Primary Choice℠, offered by Aetna Health Inc.

Which plans reach out-of-network rehab: Open Choice PPO, Open Access Managed Choice POS, HealthFund plans and Aetna Medicare PPO generally can. HMO, Open Access HMO, Aetna Select and Open Access Elect Choice EPO generally cannot, except in an emergency.

The National Advantage™ Program is worth asking about. NAP provides access to contracted rates for claims that would otherwise be paid as billed, including the out-of-network portion of managed care plans. A program showing as out-of-network may still be reachable at a negotiated rate, which can reduce your bill considerably. Ask admissions directly whether they participate. Aetna notes it does not credential providers reached through third-party contracts and does not guarantee any particular discount level, so treat it as worth checking rather than assured.

Aetna Signature Administrators® on your card means your employer is self-funding and renting Aetna’s network. Your benefits come from the employer plan document, the provider directory is separate, and appeals run under federal ERISA rules. Full detail: Aetna PPO rehab benefits and plan types.

One thing that helps across all plan types — the Aetna Behavioral Health Program lets members access covered behavioral health services directly, without a PCP referral, even where referrals are required for other specialist care.

How Long Will Aetna Pay for Rehab?

There is no fixed number of days. Aetna authorizes treatment for as long as it remains medically necessary, reviewed in increments — often 5–7 days at a time for residential care, with extensions granted on clinical progress.

In practice this means a 30, 60 or 90-day stay is possible but is not approved up front. It is approved a stretch at a time. That is normal and is not a sign the plan is trying to cut treatment short. The program’s utilization-review team handles these reviews on your behalf, and a good one is very good at it.

Pre-Authorization for Aetna Rehab

Detox, residential and PHP generally require prior authorization. Standard outpatient generally does not. The treatment program almost always obtains it for you — you should not be asked to arrange it yourself.

If authorization is denied, you have three routes and they run in sequence: internal appeal with Aetna, then external review by an independent reviewer who is not Aetna, then a complaint to your state insurance regulator. Self-funded plans are the exception — those go to the US Department of Labor rather than the state.
