How to Pay for Rehab: Who Actually Foots the Bill
Rehab is expensive, but most people never pay the sticker price. Before you assume you have to self-pay, work through the options below: your insurance (which by law must cover addiction treatment), Medicaid, free state and federally funded programs, your employer's benefits, and more. Then, if a claim gets denied, it can be appealed.
If you or someone you love is struggling, help is available now, and cost should not stop you from starting. The SAMHSA National Helpline is free, confidential, and open 24/7 at 1-800-662-HELP (4357), and can connect you with treatment and funding in your area. The 988 Suicide and Crisis Lifeline (call or text 988) is available any time.
Who can pay for rehab besides you
Roughly ordered by how many people they help. Most people qualify for more than one, so start at the top and work down.
Your health insurance (at parity)
DetailsWho: Anyone with a marketplace, employer, or other ACA-compliant plan.
Covers: Detox, MAT, IOP, PHP, and residential, at parity with medical care. Your cost is capped at your out-of-pocket maximum.
How: Confirm the level of care is authorized before admission, use an in-network program, and appeal any denial. Check your plan with our coverage tool.
Medicaid
DetailsWho: Lower-income adults and families; eligibility is broad in expansion states.
Covers: The largest payer for addiction treatment. Covers substance use disorder care in every state, usually with little or no cost sharing.
How: Apply any time (there is no open-enrollment window for Medicaid). Coverage can be retroactive in many states.
State and SAMHSA block-grant funded programs
SiteWho: People who are uninsured or low-income and do not qualify for Medicaid.
Covers: Free or low-cost treatment at state and community programs funded by federal Substance Abuse Prevention and Treatment block grants.
How: Search programs at FindTreatment.gov, or call the SAMHSA National Helpline at 1-800-662-HELP (4357), free, confidential, 24/7.
Your employer's EAP
Who: Employees (and often their household) at companies that offer one.
Covers: An assessment and a set number of short-term counseling sessions at no cost, plus a referral into treatment your plan covers.
How: Ask HR or your benefits portal for the Employee Assistance Program. It is confidential; your employer does not see that you used it or why.
VA and TRICARE
SiteWho: Veterans, active-duty service members, and military families.
Covers: Substance use disorder treatment through VA medical centers and TRICARE, including detox, residential, outpatient, and MAT.
How: Veterans can contact their VA facility or the Veterans Crisis Line (988, then press 1). TRICARE members use their regional contractor.
Sliding-scale and community programs
SiteWho: Uninsured or underinsured people, regardless of income.
Covers: Community behavioral health centers and many nonprofit programs charge on a sliding scale based on income, and some offer scholarships or grant beds.
How: Ask any program directly whether they offer sliding-scale fees, scholarships, or a grant bed. FindTreatment.gov flags low-cost options.

- Have insurance? Start there. Confirm the level of care (detox, residential, PHP, IOP) is authorized before admission, and use an in-network program so your cost stays capped at your out-of-pocket maximum.
- No insurance, or it is not enough? Apply for Medicaid (any time, no enrollment window) and call the SAMHSA Helpline at 1-800-662-HELP to find free and low-cost programs near you.
- Working? Ask HR about the Employee Assistance Program (EAP). It is confidential, often free, and can fast-track an assessment and referral.
- Get everything in writing. Save the authorization, the level of care approved, and the number of days, so you can appeal fast if the plan tries to cut the stay short.
- See the rehab cost guide for billed rates by level of care, and what insurance has to cover.
Denied, cut short, or holding a big bill?
Most rehab denials are about level of care or length of stay, not whether you qualify, and they are frequently overturned. CareRoute Bill Defense handles the appeal under parity law and negotiates any resulting bill. $0 upfront, no fee unless we save you money.

How can I pay for rehab if I do not have insurance?▾
You have real options. Medicaid covers addiction treatment in every state and you can apply any time. If you do not qualify for Medicaid, SAMHSA block grants fund free or low-cost programs for uninsured and low-income people, searchable at FindTreatment.gov or by calling 1-800-662-HELP. Many community programs also charge on a sliding scale or offer scholarship beds. Call the program directly and ask what applies to you.
Does my job's insurance or EAP cover rehab?▾
Usually yes on both counts. Employer health plans must cover addiction treatment at parity with medical care, so your cost is capped at your out-of-pocket maximum. Separately, many employers offer an Employee Assistance Program (EAP) that covers an assessment and short-term counseling at no cost and confidentially, and can refer you into covered treatment. Ask HR or your benefits portal for the EAP.
Is there free rehab?▾
Yes, for people who qualify. State and community programs funded by federal SAMHSA block grants provide free or low-cost treatment to those who are uninsured or low-income. Medicaid also covers treatment at little or no cost. Search options at FindTreatment.gov or call the SAMHSA National Helpline at 1-800-662-HELP. Availability varies by area and there can be a waitlist, so it is worth calling early.
Will Medicaid pay for rehab?▾
Yes. Medicaid is the single largest payer for addiction treatment and covers substance use disorder care in every state, typically with little or no cost sharing. There is no enrollment window, you can apply any time, and in many states coverage can be applied retroactively to recent care.
Do I have to tell my employer to use my benefits?▾
No. Using your health plan or your EAP is confidential. Your employer does not see your claims or that you contacted the EAP. If you need time off, the Family and Medical Leave Act (FMLA) can protect your job for treatment of a serious health condition without your employer learning the medical details.
What if my insurance denied rehab or cut my stay short?▾
Most rehab denials are about level of care or length of stay, not whether you qualify, and they are frequently overturned. A peer-to-peer review or an internal and external appeal, backed by the treatment team's documentation and parity law, often extends coverage. CareRoute Bill Defense can handle the appeal and any resulting bill, with no fee unless we save you money.
