Indiana Medicaid is a major payer for substance use care. Your managed care plan name still decides network doors and authorization steps.
Call 911 for emergencies. Call or text 988 for a crisis.
What to verify on your card
Plan name, member ID, behavioral health phone number, and whether you need a referral. Ask specifically about detox, residential, PHP, IOP, and OTP coverage. Note your Healthy Indiana Plan or Hoosier Healthwise / Hoosier Care Connect plan name.

MOUD access
Ask which methadone OTPs and buprenorphine clinics take your plan. Medication access should not wait on a distant residential pitch.
Indiana product lines (HIP, Hoosier Healthwise, Hoosier Care Connect) have different networks. Confirm which product is on your card before you assume a facility is in network.
If you are uninsured
Indiana public behavioral health and state-funded pathways may apply. Medicaid enrollment may be part of intake. See state-funded rehab.
Broker filter
A national call center that ignores your Indiana plan network to fill an out-of-state bed is not advocating for your coverage.

Common Questions
Does Indiana Medicaid cover rehab?
Often yes when medically necessary, subject to state plan rules, managed care networks, and authorization. Verify for your Healthy Indiana Plan or Hoosier Healthwise / Hoosier Care Connect plan name.
What about methadone and buprenorphine?
Federal Medicaid MOUD requirements apply. Ask your plan which OTPs and office-based prescribers are in network.
Is state-funded care the same as Medicaid?
Related but not identical. Uninsured pathways may run through Indiana behavioral health systems. See the state-funded sibling when available.
Will Medicaid pay for out-of-state luxury rehab?
Usually not as a default. Expect in-state network rules unless a rare exception is approved.
