Medi-Cal, California's Medicaid program, pays providers for essential primary, specialty, acute, and long-term care services delivered to more than 13 million Californians: children, their parents, pregnant women, seniors and people with disabilities, and low-income nonelderly adults. The program has undergone a major expansion due to the Affordable Care Act (ACA). Medi-Cal saw a total increase of 5.6 million enrollees between 2013 and 2017. California has also now shifted most enrollees into managed care. The Medi-Cal Facts and Figures set of materials provides an overview of Medi-Cal, covering program eligibility and enrollment, benefits, service delivery, background on policy issues, budget, and forces that affect the program's costs. A 2017 quick reference guide with updated data provides a snapshot of some key Medi-Cal data points. CHCF will publish a fully updated Medi-Cal Facts and Figures report in late 2018.
