About Lahey Health Behavioral Services Tewksbury Treatment Center
The Tewksbury Treatment Center is an addiction treatment program at 365 East Street, Saunders Building, Suite D-1, in Tewksbury, Massachusetts. The center operates under what is now Beth Israel Lahey Health Behavioral Services, having previously been known as Lahey Health Behavioral Services — a reflection of the broader Beth Israel Lahey Health system that took shape in Massachusetts after the 2019 merger.
SAMHSA’s facility record for this site documents a substantial clinical scope. Levels of care include medical detox, residential treatment, and outpatient programming. The program holds CARF accreditation and an Opioid Treatment Program (OTP) designation, allowing it to dispense medications used in opioid use disorder treatment. Conditions treated include co-occurring disorders and trauma-related concerns.
The SAMHSA population data describes an unusually broad and equity-minded patient mix: veterans, pregnant women, seniors and older adults, men, women, clients with HIV/AIDS support needs, and clients who are deaf or hard of hearing. Telehealth services and ASL accessibility are also indicated. Payment is comparably broad — Medicaid, Medicare, private insurance, self-pay, sliding scale, financial assistance, and state insurance — making the program viable for clients across a wide range of financial circumstances.
Specific program details such as current admission criteria, length of stay for residential and detox, MAT medication options, and group scheduling should be verified directly with the program. The published phone number ties to the Tewksbury campus, and prospective clients in the Merrimack Valley area can connect with the program directly for current information. Beth Israel Lahey Health Behavioral Services also operates affiliated sites that may serve as step-down or specialty resources.
