The report "Providing Health Care to Undocumented Residents: Program details and lessons learned from three California county health programs" examines three county programs in California that offer health care services to low-income undocumented residents. The report aims to serve as a resource for designing and implementing similar programs elsewhere in the nation. The report finds that many of California's counties provide primary and preventive health care services to undocumented residents through safety-net programs. The report also notes that while undocumented adults in California are generally eligible for only emergency and pregnancy-related services through Medi-Cal, undocumented children and those granted deferred action may be eligible for full-scope Medi-Cal. The report provides insights into the challenges and lessons learned from these programs, which may be useful for advocates and policymakers in other states looking for local solutions to offer non-emergency health services to undocumented immigrants.
