About Mt Sinai Beth Israel Medical Center MMD
Mt Sinai Beth Israel Medical Center’s Methadone Maintenance Division (MMD) is a hospital-based substance use treatment program located at 45 Rivington Street, 5th Floor in New York, New York. The program operates under the Mount Sinai Health System, one of New York City’s largest hospital systems, which Newsweek ranked No. 1 in New York and among the world’s best hospitals for 2026. SAMHSA classifies the program as a Substance Use Treatment facility and confirms Joint Commission (JCAHO) accreditation.
The MMD program is structured around medical detox and residential treatment for adults with opioid use disorder and other substance use diagnoses. Cognitive Behavioral Therapy is the documented evidence-based therapeutic modality, and treatment is integrated with individual and group counseling. As a hospital-affiliated program, the MMD has access to the broader Mount Sinai network for medical consultations, psychiatric services, and continuity of care, which can be especially meaningful for patients with significant medical comorbidities.
The program serves adult populations, including men, women, and Deaf or hard-of-hearing patients who can access American Sign Language services. SAMHSA records confirm co-occurring substance use and mental health conditions as treated diagnoses, which is consistent with the integrated care model that a large urban hospital system can provide. The Mount Sinai Beth Israel Lower East Side location is historically a hub for substance use services in the broader downtown Manhattan service area.
Payment options are extensive: SAMHSA confirms acceptance of Medicaid, Medicare, TRICARE, private insurance, state insurance plans, sliding-scale arrangements, and self-pay. As a Mount Sinai Health System program, insurance verification is typically coordinated through the system’s centralized billing infrastructure, and prospective patients are encouraged to contact the program directly to confirm in-network status for specific commercial plans before scheduling intake.
