How We Rank Listings
Every facility on this page is drawn from our directory of licensed and accredited treatment providers serving Cambridge and the surrounding Greater Boston area. Listings are organized to help you compare real options by the care they provide, the people they serve, and the ways they accept payment, rather than to reward whoever paid the most.
We give weight to providers that hold recognized third-party accreditation, maintain current Massachusetts licensure, and publish clear information about their services. Where a program offers medication-assisted treatment, specialized tracks, or financial assistance, we surface those details so they factor into your decision. Sponsored placements are labeled as such, and a listing’s position is not a clinical endorsement. Verify current services, availability, and insurance acceptance directly with any center before enrolling.
Rehab in Cambridge: What to Know
Cambridge sits across the Charles River from Boston in Middlesex County, a dense, academic city home to Harvard and MIT and a large student and young-adult population. The Massachusetts rehab directory lists 17 treatment providers in and around the city, weighted toward inpatient and outpatient care, covering most addiction treatment options people need close to home.
The city’s safety-net care is anchored by Cambridge Health Alliance, which provides outpatient addiction services and medication-assisted treatment, alongside the Cambridge Public Health Department and Boston-area systems a short distance away. Massachusetts also runs a single statewide front door for treatment: the Massachusetts Substance Use Helpline connects anyone to harm reduction, treatment, and recovery, free and around the clock.
Cambridge tracks its overdose data closely, and the recent trend is strongly encouraging: opioid overdoses and deaths both fell sharply in 2024. Opioid use disorder still drives most of the harm, with fentanyl, cocaine, and xylazine turning up in most fatal overdoses, so quick access to treatment and naloxone remains essential.
Cost of Rehab in Cambridge
There is no single price for rehab in Cambridge. Cost depends on the level of care, how long treatment lasts, whether a program is public or private, and what your insurance covers. Outpatient counseling is the most affordable option, medical detox and residential care cost more because they include around-the-clock supervision, and medication-assisted treatment falls in between. Local figures track Massachusetts averages, and most people pay far less than the sticker price once insurance, MassHealth, or a sliding fee scale is applied.
Most people do not pay these amounts out of pocket. Because Massachusetts expanded Medicaid, MassHealth covers the full continuum of substance use care for members who qualify, often at little or no cost, and the state funds free treatment for the uninsured through the Bureau of Substance Addiction Services. Treatment scholarships and financial assistance can help close the gap for private programs.
How to Pay for Rehab in Cambridge
Across the treatment centers listed for Cambridge, most accept self-payment and private insurance, and several also bill MassHealth or Medicare. Sliding-scale fees, financial assistance, and TRICARE are available at some programs. The cards below show how many Cambridge programs in our directory accept each payment type.
Medicare
Medicare covers medically necessary addiction treatment for eligible older adults and people with qualifying disabilities, including inpatient care, outpatient services, and counseling. Coverage and copays vary by plan, so it helps to understand how Medicare and private insurance apply to rehab before you enroll.
Medicaid (MassHealth)
Massachusetts expanded Medicaid, and MassHealth covers a broad continuum of substance use care, including acute treatment services (detox), clinical stabilization, outpatient care, and medication-assisted treatment with methadone, buprenorphine, and naltrexone. Seven Cambridge programs accept it, and Cambridge Health Alliance is a primary local route to publicly funded care.
Military Benefits
Five Cambridge programs accept TRICARE for active-duty service members, retirees, and eligible family members. Veterans can also access care through the VA, and more addiction resources for veterans and military families are available regionally.
Insurance and Private Pay
Massachusetts requires health plans to cover mental health and substance use treatment on par with other medical care, though your deductible and network still shape the final cost. Verifying benefits before admission tells you what a program will actually cost you.

Levels of Care Available in Cambridge
The centers listed for Cambridge cover most major levels of care, from medical detox and residential inpatient programs to partial hospitalization, outpatient clinics, dual diagnosis treatment, and sober living. The cards below show how many programs in each category are available locally.
Medical detox
Medical detox is the first step for people with significant physical dependence on alcohol, opioids, or other substances. Programs use around-the-clock monitoring and medication to manage withdrawal safely before a person steps into ongoing treatment.
Inpatient and residential rehab
Inpatient rehab provides 24-hour care in a structured residential setting, which suits people who need medical monitoring or a break from a high-risk environment early in recovery.
Partial hospitalization and outpatient
A partial hospitalization program offers intensive daytime treatment while clients return home in the evening, bridging residential and outpatient care. Outpatient care lets people live at home and keep working or studying while attending scheduled treatment.
Dual diagnosis care
Eleven local programs treat co-occurring disorders, addressing a substance use disorder and a mental health condition such as depression, anxiety, or PTSD at the same time, which tends to work better than treating either alone.
Sober living and aftercare
Six sober living homes provide structured, substance-free housing for people leaving treatment. Ongoing aftercare, including counseling and peer support, helps protect recovery over the long term.
Specialty Programs in Cambridge
Beyond general treatment, several Cambridge programs tailor care to specific groups and substances. The grid below shows the number of programs offering each specialty.
