Starting May 1, Felix and roughly 170,000 other undocumented children in California will have more options during such crises. They’ll gain access to not just emergency coverage but dental care, check-ups, mental health treatment and other vital services following an unprecedented Medi-Cal expansion that provides full coverage to all low-income children in the state, regardless of immigration status. . . The Medi-Cal expansion for undocumented children is exclusively state funded and is expected to cost the Department of Healthcare Services about $132 million annually.
