Does Aetna cover rehab?
Aetna sells employer and Medicare Advantage plans, and in some states runs Medicaid plans as Aetna Better Health. It stopped selling individual marketplace plans after 2025. Each kind of plan has its own network.
This is general information, not a guarantee of coverage. What your plan pays depends on your plan, your state, whether the program is in network, and whether your plan decides the care is medically necessary. Call the number on your card, then the program, before you start.
What it usually covers, by level of care
| Level of care | What to expect |
|---|---|
| Detox (medically managed withdrawal) | Usually covered when a clinician finds withdrawal needs medical monitoring. Many plans ask for prior authorization and review the stay after a few days. |
| Residential rehab | Often covered when outpatient care isn't safe or hasn't worked, but usually needs prior authorization and a review every few days. Plans often approve a shorter stay than a program recommends. |
| Partial hospitalization (PHP) | Commonly covered as a step down from residential or a step up from IOP. Expect prior authorization and regular reviews. |
| Intensive outpatient (IOP) | Commonly covered. Some plans ask for prior authorization, and some limit the weeks or hours a week. |
| Outpatient therapy and medication | Usually covered like other outpatient visits: a copay or coinsurance, and your deductible may apply. Medications for addiction are usually on the plan's drug list. |
How to check
- For mental health and substance use care, Aetna says to call the number on your member ID card.
- Ask whether the program is in network for substance use treatment under your exact plan. A carrier has many plans, each with its own network.
- Ask what prior authorization is needed, how many days are approved at first, and what you will pay a day after your deductible.
- Behavioral health is often run by a separate company named on your card. Call that number for benefits.
- Individual and small-group plans, on or off the marketplace, must cover mental health and substance use treatment (older "grandfathered" plans are the exception). Under the federal parity law, most plans that cover it can't make its copays, visit limits or prior authorization stricter than for other medical care.
Call a program and ask
Call the program and ask them to verify your benefits; it's free and takes a few minutes.
- Do you accept Aetna for substance use treatment, and for which levels of care?
- Are you in network for my exact plan, and is prior authorization needed?
- What would I pay a day or a week, and when is the next opening for an assessment?
