Insurance

Rehab insurance coverage is the biggest factor in what addiction treatment will cost you. Most health plans in the U.S. cover drug and alcohol treatment, but how much they pay depends on your insurer, your plan type, your network and whether the care is approved in advance.

This page brings together our guides to paying for rehab with insurance, so you can find the one that matches your situation. We are an independent information service and are not affiliated with any insurance company.

Does Insurance Cover Rehab?

In most cases, yes. Under the Affordable Care Act, Marketplace plans must cover substance use disorder services as an essential health benefit, and federal parity rules generally require most plans to cover addiction treatment on terms no more restrictive than medical care. HealthCare.gov explains these protections. Our guide to whether insurance covers 30-day rehab goes deeper.

Rehab Insurance by Plan Type

• Private insurance rehab: how employer and individual plans compare
• PPO insurance rehab: more choice, including out-of-network care
• HMO insurance for rehab: lower costs with network and referral rules
• In-network vs out-of-network rehab: why the network matters so much

Public Coverage for Rehab

• Medicaid 30-day rehab: low-cost care with state-by-state rules
• Medicare 30-day rehab: what Parts A, B and D cover, and the gaps
• TRICARE for service members, retirees and families

What Affects Your Rehab Insurance Coverage

• Medical necessity: the plan decides which level of care is needed based on a clinical assessment
• Prior authorization: most plans must approve detox, residential and partial hospitalization care in advance
• Network: in-network programs usually cost far less
• Cost sharing: your deductible, copays, coinsurance and out-of-pocket maximum set your share

See the cost of 30-day rehab for how these add up.

How to Use Your Rehab Insurance Coverage, Step by Step

1. Find your plan details. Note your insurer, plan type (HMO, PPO, EPO) and member ID from your card.
2. Get an assessment. A licensed clinician recommends a level of care, such as detox, residential or outpatient treatment.
3. Confirm the network. Ask whether the program is in network for your exact plan, not only for the insurer in general.
4. Request prior authorization. The facility usually sends your assessment to the plan and receives an approval for a set number of days.
5. Get a cost estimate. Ask for your expected share in writing, including deductible, coinsurance and any services billed separately.
6. Plan the next step. Before discharge, make sure step-down care is approved so there is no gap in treatment.

If your plan denies coverage or approves fewer days than your care team recommends, ask for the decision in writing. You have the right to appeal, and many denials are overturned when a clinician explains why the care is needed.

No Insurance? You Still Have Options

State-funded programs, sliding-scale fees and grant-funded care can make treatment possible without coverage. Read our guide to no insurance rehab options.
