About Boston Medical Center
Boston Medical Center’s Office-Based Addiction Treatment (OBAT) clinic operates at 801 Massachusetts Avenue, 5th Floor, Suite C, in Boston’s South End. As part of one of the largest safety-net hospital systems in New England and a flagship of the BMC Grayken Center for Addiction, OBAT provides outpatient medication-based treatment for opioid use disorder, alcohol use disorder, and related substance use conditions, integrated with the rest of BMC’s primary care and specialty network.
The OBAT model is built around buprenorphine and naltrexone prescribed in a primary-care setting, paired with nurse care management, behavioral health support, and consultation from addiction medicine specialists. Patients can receive their addiction treatment in the same medical home that manages their hypertension, HIV care, OB care, or pediatric needs, eliminating the silo between substance use treatment and general medicine. The clinic explicitly serves adolescents, young adults, pregnant women, and patients living with HIV/AIDS, and works closely with BMC’s well-known addiction research enterprise.
Clinical leadership in BMC’s addiction enterprise includes physician researchers like Alex Walley, MD, MSc, whose work spans treatment policy, overdose prevention, and clinical addiction medicine. The Grayken Center umbrella supports clinician training, research, and quality improvement that flows back into bedside care at OBAT.
BMC is accredited by The Joint Commission and recognized by NCQA, and accepts MassHealth, BMC HealthNet Plan, Medicare, TRICARE, and commercial insurance, with financial assistance available through the hospital’s safety-net mission. The OBAT clinic is not a detox unit or a residential program; patients needing inpatient withdrawal management are referred to BMC partners and returned to OBAT for ongoing outpatient care.
