Health care reform aims to expand access to care through the expansion of Medicaid eligibility and the creation of private health insurance marketplaces with subsidies. For people living with HIV/AIDS, this means transitions from existing programs like Ryan White to new forms of coverage through Medicaid expansion or Covered California. However, some populations are left out of the reform, including undocumented immigrants. California is implementing reforms through the expansion of Medi-Cal eligibility and the creation of Covered California. Transition assistance will be needed to help people living with HIV/AIDS and providers navigate the new systems and address ongoing needs.
