This week, our In Focus section reviews the California Advancing and Innovating Medi-Cal (CalAIM) proposal, issued by the California Department of Health Care Services (DHCS) on October 28, 2019. CalAIM would implement broad delivery system, program, and payment reform for the state’s Medicaid program. The proposal includes efforts to address social determinants of health and other policy priorities such as homelessness, lack of access to behavioral health care, children with complex medical conditions, justice-involved populations, and aging individuals.
