Ohio Medicaid does cover rehab. The program pays for substance use disorder treatment across every major level of care, including outpatient counseling, intensive outpatient programs, medication-assisted treatment, medically supervised detox, and residential rehab in certified facilities. Coverage applies to everyone enrolled in Ohio Medicaid, including adults who qualify through the state’s Affordable Care Act expansion.
Rehab Services Ohio Medicaid Pays For
Ohio Medicaid uses the American Society of Addiction Medicine (ASAM) criteria to match a person to the right level of care based on a clinical assessment. The covered services span the full continuum:
- Outpatient individual, group, and family counseling for substance use disorders.
- Intensive outpatient programs (ASAM Level 2), which generally do not require prior authorization when they run under 20 hours per week.
- Partial hospitalization (ASAM Level 2.5), a higher-intensity outpatient option that may require prior authorization.
- Residential treatment in certified facilities, covering ASAM Levels 3.1 through 3.7, including medically monitored inpatient care.
- Withdrawal management (detox), both outpatient and facility-based, including clinically managed and medically monitored residential withdrawal.
- Medication-assisted treatment, including buprenorphine, naltrexone, and methadone.
- Peer recovery support delivered by certified peer supporters with lived experience of recovery.
- Targeted case management to connect people in treatment with medical and social services.
Behavioral health under Ohio Medicaid covers both mental health conditions and substance use disorders, so someone with co-occurring issues can receive integrated treatment under one benefit.
Medication-Assisted Treatment
All three FDA-approved medications for opioid use disorder are covered. Buprenorphine products such as Suboxone and the injectable Sublocade are on Ohio Medicaid’s preferred drug list, so standard doses do not require prior authorization. Vivitrol, the injectable form of naltrexone, is also preferred and does not require authorization; it can be given in a physician’s office, and unlike buprenorphine, patients are not required to be enrolled in counseling as a condition of the prescription.
Methadone is covered but has to be dispensed through an accredited outpatient narcotic treatment program, and patients receiving it must be enrolled in or provide proof of substance use disorder counseling.
For buprenorphine, Ohio Medicaid caps daily doses at standard limits — 24 milligrams per day for Suboxone and Subutex, for example. A prescriber who wants to go higher must submit documentation showing the higher dose is medically necessary.
How Long Residential Rehab Is Covered
Residential stays are governed by Ohio Administrative Code 5160-27-09. For the first and second admissions in a calendar year, the first 30 consecutive days are covered without prior authorization. To stay longer, the provider has to obtain authorization by documenting continued medical necessity. A third or later admission in the same calendar year needs authorization from day one.
Residential programs have to be certified by the Ohio Department of Behavioral Health, the agency formerly known as the Ohio Department of Mental Health and Addiction Services and renamed in November 2025. Higher-intensity residential levels must deliver at least 30 hours per week of treatment programming, including a minimum of 10 hours of individual, group, or family counseling. Meals, free time, self-help meetings such as AA or NA, and housekeeping do not count toward those hours.
The residential per diem rate bundles most services together, including assessments, crisis intervention, therapy, case management, peer recovery support, and urine drug screens. Residential providers either offer medication-assisted treatment on-site or arrange access to it off-site.
Larger residential facilities are reachable through Medicaid under a Section 1115 demonstration waiver that lets the state pay for short-term SUD treatment in Institutions for Mental Diseases (facilities with more than 16 beds that primarily treat behavioral health). The waiver was first approved in September 2019 and is currently set to expire on December 31, 2026. Length of stay under the waiver is determined by medical necessity rather than a fixed federal cap, with managed care utilization review in the background.
Prior Authorization Rules by Service
Most Ohio Medicaid members are in a managed care plan — Buckeye Health Plan, CareSource, Molina Healthcare, Paramount Advantage, or UnitedHealthcare Community Plan. Each plan runs its own authorization process, but the Ohio Department of Medicaid has set statewide behavioral health standards so the rules do not drift too far between plans. Those standards require that authorizations kick in only above reasonable clinical thresholds, that standardized forms be used, and that no service be reduced or denied without an individualized clinical review. Members already in treatment are protected from abrupt disruptions.
For substance use disorder services, the common thresholds are:
- Residential treatment: review after 30 days or on a third admission in the same calendar year.
- Withdrawal management, ambulatory or residential: authorization after seven consecutive days.
- Intensive outpatient: authorization after 30 units in a calendar year.
Managed care plans have to process expedited authorization requests for residential SUD treatment within 48 hours. Providers submit through the Availity portal with clinical documentation that typically includes ASAM dimension ratings, a current treatment plan with measurable goals, and progress notes.
What Ohio Medicaid Will Not Pay For
A few categories are explicitly excluded from behavioral health reimbursement. Room and board is not covered as a standalone cost, though it is folded into the residential per diem rate. Educational and vocational training, recreational activities such as art or equine therapy, and transportation are excluded. Habilitation services like supportive housing assistance and basic life skills training also fall outside the behavioral health benefit.
Telehealth for Addiction Treatment
Ohio law requires Medicaid to cover telehealth, including audio-only visits, on the same basis as in-person care. Community behavioral health providers certified under Medicaid can deliver SUD treatment remotely, and an in-person visit is not required before starting treatment. Under a state-level exception, prescribers can initiate controlled substance prescriptions via telehealth for patients with substance use disorders, though federal DEA rules may add their own restrictions. Medicaid’s telehealth rule does require an annual in-person visit, but that does not block someone from beginning treatment virtually.
Who Qualifies for Ohio Medicaid
Ohio expanded Medicaid under the Affordable Care Act, which opens eligibility to adults ages 19 through 64 with household incomes up to 138 percent of the federal poverty level (with a built-in 5 percent income disregard). For a single adult, that works out to roughly $1,735 a month. Nearly 770,000 Ohioans were covered through the expansion group as of March 2025.
Children qualify at higher income thresholds, up to 211 percent of the federal poverty level. Pregnant women are eligible up to 205 percent, with coverage continuing for 12 months after delivery. Older adults and people with disabilities may also qualify, but these groups face asset limits in addition to income tests.
Enrollment is open year-round. You can apply online at benefits.ohio.gov, by phone at 800-324-8680, or in person at a county Department of Job and Family Services office. The state advises applying even if you are unsure whether your income falls within the limits.
Finding a Rehab That Takes Ohio Medicaid
Several resources help locate treatment facilities that accept Medicaid:
- SAMHSA’s treatment locator at findtreatment.gov, which filters by insurance type and location.
- The Ohio Department of Behavioral Health, which maintains a provider search tool and runs a Consumer and Family Toll-Free Bridge at 877-275-6364.
- Each managed care plan’s online provider directory. Being “Medicaid-accepting” does not guarantee a facility is in your specific plan’s network, so verify.
- The Ohio Medicaid Consumer Hotline at 800-324-8680 for help with eligibility, covered services, or finding a provider.
- County ADAMH boards, which coordinate local treatment resources. A directory is available through the Ohio Association of County Behavioral Health Authorities at oacbha.org.
When you call a facility, have your Medicaid card and member ID handy. Ask whether they are accepting new Medicaid patients, which managed care plans they are in-network with, and whether any out-of-pocket costs apply. Most Medicaid-covered services carry no cost to the patient, though small copays of a few dollars may apply to some appointments or prescriptions. Pregnant women, minors, and people receiving emergency services are generally exempt from copays.
