Treatment Centers in Indiana That Accept Indiana Medicaid

Does Indiana Medicaid Cover Rehab in Indiana?

Yes. Indiana Medicaid covers drug and alcohol rehab in all 92 counties, and state member pages list mental health care and substance use services under both Package A, the standard benefit, and Package C, the children’s CHIP benefit. A member looking for Indiana drug and alcohol rehabs has the same benefit whichever plan is on the card.

Indiana Medicaid is the state’s Medicaid program, run by the Family and Social Services Administration, whose Division of Mental Health and Addiction certifies addiction providers and designates residential levels of care. Four programs run through contracted health plans, and Traditional Medicaid pays enrolled providers directly. Behavioral health sits inside each plan; there is no separate statewide behavioral health vendor.

Which health plans run Indiana Medicaid in 2026?

Five health plans run Indiana Medicaid in 2026: Anthem, CareSource, Managed Health Services (MHS), UnitedHealthcare and Humana. Anthem is the only one in all four managed care programs. MDwise left HIP and Hoosier Healthwise on January 1, 2026; its members moved to Anthem, CareSource or MHS, and authorizations already granted were honored during the move.
