The Behavioral Health Medicaid Waiver Act establishes a framework for providing support and services to individuals with behavioral health conditions in New Mexico. The Act defines key terms such as "behavioral health condition," "brain injury," "eligible person," "serious emotional disturbance," "serious mental illness," and "substance use disorder." It mandates the health care authority to acquire, provide, or coordinate services through a Medicaid waiver program, contingent upon federal approval and available appropriations. The authority is also tasked with developing individual support and service plans through interdisciplinary teams and engaging stakeholders in the rule-making process to ensure comprehensive service delivery.

Beginning in July 2025, the health care authority is required to hold monthly meetings with various stakeholders, including individuals with behavioral health conditions and their families, to develop an application for a Medicaid waiver program. This program aims to provide home- and community-based services and supports tailored to the needs of eligible individuals. The authority must submit this application to the federal Centers for Medicare and Medicaid Services by July 1, 2026, ensuring that the program is designed to meet the specific needs of New Mexico residents with behavioral health conditions.
