Private insurance includes plans you get through an employer, plans you buy on the Health Insurance Marketplace, and plans bought directly from an insurer. Understanding a few key ideas can save you money and stress.
What laws require insurance to cover addiction treatment?
Two federal laws do most of the work:
- The Affordable Care Act (ACA). Individual and small-group plans must cover 10 essential health benefits. Mental health and substance use disorder services are one of them.
- The Mental Health Parity and Addiction Equity Act (MHPAEA). If a plan covers addiction treatment, it can't make that coverage harder to use than medical or surgical care. That applies to copays, visit limits and approval rules.
Large employer plans aren't required to cover the essential health benefits, but nearly all do cover addiction treatment, and parity rules apply when they do.

What levels of care does private insurance cover?
Most plans cover the full range of care, subject to medical necessity:
| Level of care | What it is |
|---|---|
| Detox | Medically supervised withdrawal, usually a few days to about a week |
| Residential treatment | Live-in care with 24-hour support |
| Partial hospitalization (PHP) | Day treatment, often five or more hours a day |
| Intensive outpatient (IOP) | Several sessions a week while living at home |
| Outpatient | Weekly or less frequent therapy |
| Medication-assisted treatment (MAT) | FDA-approved medicine plus counseling |
Withdrawal from alcohol or benzodiazepines can be life-threatening. If you or a loved one is stopping either one, do it under medical supervision.
How do insurers decide what to approve?
Insurers decide based on medical necessity. Many use the ASAM Criteria, guidelines from the American Society of Addiction Medicine that look at things like withdrawal risk, health conditions, mental health, readiness for change, relapse risk and your living situation.
Higher levels of care often need prior authorization, which is approval before treatment starts. Then the insurer does concurrent reviews during treatment to decide whether to keep paying. That is why coverage is often approved a few days or weeks at a time.
What will you pay out of pocket?
Your costs depend on these parts of your plan:
- Deductible: what you pay before the plan starts sharing costs.
- Copay or coinsurance: a flat fee or percentage you pay for each service.
- Out-of-pocket maximum: the most you pay for covered, in-network care in a plan year. After you reach it, the plan pays 100% of covered in-network services.
- Network: in-network programs have agreed rates with your insurer. Out-of-network programs may cost much more.
Does your plan type matter?
Yes. Your plan type shapes where you can go.
- HMO: usually in-network only, and may require a referral from a primary care provider.
- PPO: in-network and out-of-network coverage, with higher costs out of network.
- EPO: in-network only, usually without referrals.
Plans also vary by state and employer. Two people with the same insurance company can have very different benefits. Learn more in our guide to whether insurance covers rehab, or see carrier-specific pages for Aetna and Blue Cross Blue Shield.
What if your insurer denies coverage?
A denial isn't always final. Ask for the decision in writing, including the reason and the clinical criteria used. Your treatment program can often send more records or request a peer-to-peer review, where its clinician talks with the insurer's reviewer.
If that doesn't work, file a formal internal appeal. Urgent cases can often be reviewed faster. If the internal appeal fails, you can usually request an external review by an independent reviewer. Keep copies of letters and notes from every call, including dates and names. Parity law also gives you the right to ask how the plan's limits on addiction care compare with its limits on medical care.
How do you find rehabs that accept your insurance?
- Call member services. The number is on the back of your insurance card. Ask about behavioral health or substance use benefits.
- Ask about each level of care. Ask what's covered, what needs prior authorization and what you'll owe.
- Get an in-network list. Ask for in-network addiction programs near you.
- Search by state. Try pages like New Jersey programs that take private insurance or Massachusetts programs that take private insurance.
- Let the program verify. Most programs will check your benefits before admission.
If your insurance won't cover what you need, ask about self-pay options and payment plans.
The bottom line
Private insurance usually covers addiction treatment, but your network, deductible and medical necessity reviews shape what you pay. Check before you commit, and get approvals in writing when you can.
