Rehab Centers in Boston, Massachusetts

Massachusetts Medicaid — MassHealth — is among the most comprehensive in the country for addiction care, and the state expanded Medicaid under the ACA. Of the 614 facilities in our Massachusetts directory, 380 list Medicaid/MassHealth among accepted payments. MassHealth covers acute treatment services (detox), clinical stabilization, residential rehab, intensive outpatient (IOP), and all three MAT medications, authorized on medical necessity — asking for “detox Massachusetts MassHealth” at intake is routine, and programs verify eligibility same-day. Call the program directly or our helpline at (833) 567-5838 for a same-day MassHealth check.

Massachusetts runs one of the strongest public treatment systems in the U.S. through the Bureau of Substance Addiction Services (BSAS): state-funded detox, residential, and outpatient programs serve residents regardless of insurance. The fastest route to a bed is the Massachusetts Substance Use Helpline at (800) 327-5050 (helplinema.org) — free, confidential, 24/7, with live availability across the state; it is the practical “Massachusetts detox beds list” people search for, updated in real time. Free detox in Massachusetts is reachable the same day in most regions; 123 detox programs are listed in this directory.

Massachusetts sticker prices run above the national average: medical detox roughly $300–$1,000 per day, standard inpatient rehab $15,000–$32,000 for 30 days, IOP $3,500–$10,000 per course, and outpatient counseling $60–$175 per session (industry estimates). Most residents pay far less: the state’s 2014 landmark parity and addiction laws plus federal parity require commercial plans — including Blue Cross Blue Shield of Massachusetts — to cover addiction treatment at parity with medical care, MassHealth covers low-income residents comprehensively, and BSAS fills the gaps.

Yes — to the lowest level in over a decade. Massachusetts recorded 978 opioid-related overdose deaths in 2024, down 37% from 1,336 in 2023 — the first year under 1,000 since 2013, with declines across every race and ethnicity, per the Massachusetts Department of Public Health. Boston saw a 38% decline. DPH credits expanded naloxone access (available at Massachusetts pharmacies without a personal prescription under a statewide standing order), broader MAT availability, and harm-reduction outreach. The state’s Good Samaritan law protects people who call 911 during an overdose.

Treatment is spread more evenly across Massachusetts than in most states. Central MA is anchored by Worcester — the state’s largest cluster with 38 centers. Greater Boston lists Boston (25), Quincy (12), and Framingham (14) in the MetroWest. Western MA runs through Springfield (22), and the South Coast — the region hit hardest by the opioid crisis — through New Bedford (22), Brockton (19), and Fall River (13). Statewide placement through the (800) 327-5050 helpline works regardless of your home city.
