Authorizes provision of residential mental health services in residential substance use disorders treatment facility or program under specified hospital affiliation and clinical support criteria.

This bill allows licensed residential substance use disorder treatment facilities in New Jersey to offer residential mental health services, provided they have a formal contractual agreement with a hospital that offers psychiatric or medical support. The law requires these facilities to maintain joint clinical governance, shared treatment protocols, 24-hour psychiatric and medical consultation availability, and clear procedures for transferring patients to inpatient care when needed. Facilities must file their hospital affiliation agreements with the Department of Health and follow existing state regulations for residential mental health treatment. The measure aims to create a structured pathway for treating individuals with co-occurring mental health and substance use disorders in a sub-acute residential setting that bridges inpatient hospitalization and outpatient care.
