Rural Wellness Act This bill prioritizes behavioral and mental health treatment services under certain rural development grant and loan programs. The bill also reauthorizes through FY2028 the set-asides and prioritizations for substance use disorder treatment services under the Department of Agriculture's (1) Community Facilities Direct Loan and Grant Program, (2) Rural Health and Safety Education Competitive Grants Program, and (3) Distance Learning and Telemedicine Grant Program. Under the community facilities program, the bill prioritizes direct loans and grants for the development of behavioral and mental health services facilities, including facilities that provide treatment services. Further, loans and grants provided under the program may be used to develop facilities and systems to provide telehealth services for behavioral and mental health treatment. Under the Rural Health and Safety Education Competitive Grants Program, the bill prioritizes grants for behavioral and mental health education and treatment. Under the Distance Learning and Telemedicine Grants Program, the bill includes a 17% set-aside for telemedicine projects that provide substance use disorder treatment services (currently a 20% set-aside).
