Paying for Rehab & Insurance
How to pay for addiction treatment using insurance, Medicaid, or a marketplace plan - plus the parity law and low-cost options if you are uninsured.
Updated
Cost should not be the reason someone goes without help. Most people pay for addiction treatment through insurance, public programs, or a combination - and free and low-cost options exist for those who are uninsured.
Your coverage rights
The Mental Health Parity and Addiction Equity Act (MHPAEA) requires most health plans to cover mental-health and substance use treatment on terms comparable to other medical care. Under the Affordable Care Act, substance use treatment is an essential health benefit, so Marketplace plans and Medicaid expansion coverage must include it.
Common ways to pay
- Private insurance - employer or Marketplace plans typically cover detox, inpatient, and outpatient care. Confirm in-network facilities and your share of the cost before you start.
- Medicaid - every state’s program covers some addiction treatment, often with little or no out-of-pocket cost, though specific services vary by state.
- Medicare - covers medically necessary substance use services for those who qualify.
- Uninsured or underinsured - many programs offer sliding-scale fees, payment plans, or state- and SAMHSA-funded free care.
How to verify your benefits
- Call the member-services number on the back of your insurance card.
- Ask which facilities are in-network and which levels of care are covered.
- Ask about prior authorization, your deductible, copays, and your out-of-pocket maximum.
- Confirm the same details directly with the treatment facility.

Does health insurance cover rehab?
Usually, yes. Many plans cover substance use treatment, and the Mental Health Parity and Addiction Equity Act requires plans that offer these benefits to provide them on terms no more restrictive than other medical care. Coverage details - such as which facilities are in-network and how much you pay - vary by plan, so verify benefits with your insurer.
What if I do not have insurance?
You still have options. Every state's Medicaid program covers some substance use treatment, and many programs offer sliding-scale fees, payment plans, or state-funded and SAMHSA-funded free care. Call SAMHSA at 1-800-662-HELP (4357) for free referrals to low-cost programs.
Does Medicaid cover addiction treatment?
Yes. Every state's Medicaid program covers some substance use disorder treatment, though the specific services and providers vary by state. Contact your state Medicaid office or use findtreatment.gov to filter for programs that accept Medicaid.
What questions should I ask my insurer?
Ask which facilities are in-network, what levels of care are covered (detox, inpatient, outpatient), whether prior authorization is required, and what your deductible, copays, and out-of-pocket maximum are. The member-services number is on the back of your insurance card.
