The California Medical Assistance Program (Medi-Cal or MediCal) is California's Medicaid program serving low-income individuals, including families, seniors, persons with disabilities, children in foster care, pregnant women, and childless adults with incomes below 138% of federal poverty level. Benefits include ambulatory patient services, emergency services, hospitalization, maternity and newborn care, mental health and substance use disorder treatment, dental (Denti-Cal), vision, and long-term care and supports. Approximately 13.3 million people were enrolled in Medi-Cal as of January 2018, or about one-third of California's population; in Tulare County and Merced County, more than 50% of county residents were enrolled as of September 2015.
