Assembly Member Krell's proposal to modify California's full-service partnership programs establishes new presumptive eligibility criteria for individuals with serious mental illness who face specific high-risk circumstances. The legislation defines five categories of presumptive eligibility: individuals experiencing unsheltered homelessness, those transitioning from extended stays in secured treatment settings, people with multiple recent emergency department visits for psychiatric events, individuals leaving state prison or county jail after six months or more, and those with multiple recent arrests.

The bill maintains counties' existing full-service partnership requirements while adding flexibility in implementation. Counties retain discretion to limit enrollment based on available funding from the Behavioral Health Services Fund, and those with populations under 200,000 may request exemptions from certain service requirements. The legislation specifies that services must include mental health care, substance use treatment, housing interventions, and evidence-based practices delivered through a whole-person approach.

To promote cultural responsiveness, the bill incorporates community-defined evidence practices alongside traditional treatment models. These practices reflect the values, histories, and lived experiences of served communities, as determined through community consensus. The State Department of Health Care Services maintains oversight of documentation standards and service planning requirements, while counties must maintain detailed clinical records of all services provided to enrolled individuals.
