This bill permanently establishes and expands certified community behavioral health clinics, which provide comprehensive mental health and substance abuse treatment services. The legislation makes three major changes: it creates a payment system under Medicaid for these clinics based on their actual operating costs, extends Medicare coverage to include their services starting January 1, 2024, and authorizes $552.5 million annually through 2028 in federal grants to help clinics operate and meet certification standards. The bill affects mental health providers, people with behavioral health needs, and states implementing Medicaid programs. Additional funding of $6 million per year supports technical assistance for clinics, and $51 million annually supports a data collection system to track clinic performance and outcomes.
