MOUD access
Ask which methadone OTPs and buprenorphine clinics take your plan. Medication access should not wait on a distant residential pitch.
If you are uninsured
Massachusetts Behavioral Health Help Line (833-773-2445) and CBHC pathways may apply. Medicaid enrollment may be part of intake.

A national call center that ignores your Massachusetts plan network to fill an out-of-state bed is not advocating for your coverage.

Common Questions
Does Massachusetts Medicaid cover rehab?
Often yes when medically necessary, subject to state plan rules, managed care networks, and authorization. Verify for your specific 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 Massachusetts Behavioral Health Help Line (833-773-2445) and CBHC pathways.
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.
