12 weeks of unpaid, job-protected leave for treatment. Your employer must maintain your health insurance. You don't need to share your diagnosis. Applies to employers with 50+ employees.

Frequently Asked Questions
Does health insurance cover drug and alcohol rehab?
Yes. Under the Affordable Care Act (ACA), substance use disorder treatment is one of 10 Essential Health Benefits that all marketplace and most employer plans must cover. The Mental Health Parity and Addiction Equity Act (MHPAEA) requires that insurance companies cover addiction treatment at the same level as physical health conditions. This includes detox, inpatient rehab, outpatient treatment, medication-assisted treatment (MAT), and therapy.
How much does rehab cost with insurance?
With insurance, out-of-pocket costs for rehab typically range from $0–$5,000 depending on your plan's deductible, copay, coinsurance, and whether the facility is in-network. A $20,000 inpatient program might cost you $2,000–$4,000 after insurance. If you've met your out-of-pocket maximum, additional covered services cost $0. Most facilities offer free insurance verification before admission.
How much does rehab cost without insurance?
Without insurance, costs vary dramatically: outpatient programs range from $1,000–$10,000, intensive outpatient (IOP) costs $3,000–$15,000, standard inpatient rehab costs $6,000–$30,000 for 30 days, and luxury programs can exceed $50,000–$100,000+. However, free and low-cost options exist - state-funded programs, sliding-scale clinics, and SAMHSA-funded facilities serve millions of uninsured Americans annually.
What types of treatment does insurance cover?
Most insurance plans cover: medical detox, inpatient/residential rehab, partial hospitalization (PHP), intensive outpatient (IOP), standard outpatient counseling, medication-assisted treatment (MAT) including Suboxone and Vivitrol, psychiatric evaluation, individual and group therapy, and aftercare planning. Services typically not covered include luxury amenities, unproven experimental treatments, and long-term sober living.
Can I go to rehab if I don't have insurance?
Absolutely. Options include: state-funded treatment programs (funded by $1.8B in SAMHSA block grants), Federally Qualified Health Centers (sliding-scale fees), Medicaid (apply at Healthcare.gov), nonprofit and faith-based programs, university behavioral health clinics, and VA services for veterans. Call SAMHSA's helpline at 1-800-662-4357 for free referrals to local programs.
Will I lose my job if I go to rehab?
The Family and Medical Leave Act (FMLA) provides up to 12 weeks of unpaid, job-protected leave for addiction treatment. Your employer must hold your position and maintain your health insurance. You don't need to disclose your diagnosis - only that you need medical leave. The ADA provides additional protections for people in recovery. FMLA applies to employers with 50+ employees; many states have broader protections.
How do I verify my insurance coverage for rehab?
Three ways: (1) Call the number on the back of your insurance card and ask about behavioral health/substance use benefits. (2) Contact treatment facilities directly - most offer free insurance verification. (3) Log into your insurance portal online and check your summary of benefits. Key questions to ask: Is this facility in-network? What's my deductible? Do I need preauthorization? What levels of care are covered?
Does Medicaid cover rehab?
Yes. Medicaid covers substance use treatment in all states, including detox, inpatient, outpatient, MAT, and mental health services. Medicaid is the largest payer for behavioral health services in the U.S. In expansion states, individuals earning up to 138% of the Federal Poverty Level (~$20,800/year for a single person) qualify. Coverage specifics vary by state.
Does Medicare cover addiction treatment?
Yes. Medicare Part A covers inpatient detox and rehab. Part B covers outpatient therapy, PHP, IOP, MAT (including methadone through OTPs), and psychiatric services. Part D covers addiction medications like buprenorphine, naltrexone, and naloxone. Standard cost-sharing applies: Part A deductible, Part B's 20% coinsurance after annual deductible.
Can I use my HSA or FSA to pay for rehab?
Yes. The IRS classifies substance use disorder treatment as a qualified medical expense. You can use HSA (Health Savings Account) and FSA (Flexible Spending Account) funds for rehab costs including deductibles, copays, coinsurance, and out-of-pocket expenses. This effectively lets you pay with pre-tax dollars, reducing your cost by 20–35% depending on your tax bracket.
Are rehab costs tax-deductible?
Yes. Addiction treatment qualifies as a deductible medical expense under IRS rules. You can deduct unreimbursed medical expenses that exceed 7.5% of your adjusted gross income. Deductible expenses include program fees, prescribed medications, transportation to treatment, and room and board during inpatient care. Keep all receipts and consult a tax professional.
What is the Mental Health Parity Act?
The Mental Health Parity and Addiction Equity Act (MHPAEA) is a federal law requiring insurance companies to cover mental health and substance use disorder treatment at the same level as medical/surgical care. This means equal copays, equal visit limits, equal preauthorization requirements, and equal coverage duration. The law applies to most employer-sponsored plans and all ACA marketplace plans.
