Does Medicaid Cover Rehab in Indiana? Healthy Indiana Plan Explained
Indiana Medicaid (Healthy Indiana Plan) covers comprehensive addiction treatment including detox, residential, outpatient, IOP, and MAT. Learn eligibility, covered services, and how to enroll.
If you or a loved one needs addiction treatment in Indiana but worry about the cost, here's the most important thing to know: Indiana Medicaid — known as the Healthy Indiana Plan (HIP) — covers comprehensive substance use disorder treatment, from medical detox to long-term outpatient care. And nearly 88% of Indiana treatment facilities accept it.
This guide explains exactly what HIP covers, who qualifies, how to enroll, and what to do if you don't qualify — so insurance never stands between a Hoosier and recovery.
Indiana Medicaid (HIP) covers all major levels of addiction treatment — including detox, residential, outpatient, IOP, and medication-assisted treatment. Individual income eligibility: up to $22,026/year (138% FPL).
What Is the Healthy Indiana Plan (HIP)?
The Healthy Indiana Plan is Indiana's expanded Medicaid program for low-income adults aged 19 to 64. Unlike traditional Medicaid programs in other states, HIP uses a consumer-driven model with two tiers:
- HIP Basic: For individuals earning below 100% of the federal poverty level (FPL). Covers essential health services including substance use treatment. No monthly contribution required.
- HIP Plus: For individuals earning up to 138% FPL (approximately $22,026/year for an individual). Includes enhanced benefits, a POWER Account (Personal Wellness and Responsibility Account), and vision and dental coverage.
Both tiers cover substance use disorder treatment services. The POWER Account in HIP Plus works like a health savings account — members contribute a small monthly amount (based on income), and the state matches it for preventive care and qualified health expenses.
HIP Basic vs. HIP Plus: Coverage Differences
| Feature | HIP Basic | HIP Plus |
|---|---|---|
| Income Level | Below 100% FPL | Up to 138% FPL |
| Addiction Treatment | Covered | Covered |
| Medical Detox | Covered | Covered |
| MAT (Suboxone, Vivitrol) | Covered | Covered |
| Vision & Dental | Not included | Included |
| POWER Account | No | Yes |
| Monthly Contribution | None | 2% of income |
What Rehab Services Does Medicaid Cover?
Indiana Medicaid covers the full continuum of evidence-based addiction treatment services. In 2018, Indiana received a federal Section 1115 waiver that specifically expanded coverage for substance use disorder treatment, including stays in Institutions for Mental Diseases (IMDs) — which means residential treatment centers are covered, not just outpatient.
Covered services include:
- Medical detoxification — medically supervised withdrawal management
- Residential/inpatient treatment — 24/7 structured care in a treatment facility
- Outpatient treatment — individual and group counseling sessions
- Intensive Outpatient Programs (IOP) — structured programs of 9+ hours per week
- Partial Hospitalization Programs (PHP) — day programs with 20+ hours per week
- Medication-Assisted Treatment (MAT) — buprenorphine (Suboxone), naltrexone (Vivitrol), and methadone
- Peer recovery coaching — support from individuals with lived recovery experience
- Assessment and evaluation — ASAM-criteria-based placement assessments
- Crisis intervention services
- Aftercare and continuing care planning
Indiana's Section 1115 Medicaid waiver specifically expanded coverage for residential SUD treatment — meaning HIP covers stays at inpatient facilities, which many state Medicaid programs do not.
How to Check Your Eligibility
You may qualify for HIP if you meet these criteria:
- Age: 19 to 64 years old
- Residency: Indiana resident
- Citizenship: U.S. citizen or qualified non-citizen
- Income: Individual income up to $22,026/year; couple up to $29,870; family of four up to $45,546
- Not currently covered by Medicare or other qualifying insurance
To check your eligibility:
- Visit in.gov/fssa/hip
- Call 877-GET-HIP9 (877-438-4479)
- Visit your local FSSA Division of Family Resources office
Prior Authorization Requirements
Some addiction treatment services under HIP require prior authorization — meaning the managed care plan must approve the service before treatment begins. This typically applies to:
- Residential treatment stays (authorization usually granted in 7–14 day increments)
- Extended outpatient programs beyond initial assessment visits
- Certain medications (though most MAT medications have streamlined authorization)
Your treatment facility typically handles prior authorization on your behalf. If authorization is denied, you have the right to appeal. Indiana's managed care organizations — including Anthem, CareSource, MHS Indiana, and MDwise — each have appeal processes outlined on their member portals.
