In this report, we provide an overview and assessment of the Governor's California Advancing and Innovating Medi-Cal (CalAIM) proposal, also known as Medi-Cal Healthier California for All. CalAIM would make far-reaching reforms to Medi-Cal that would increase the program’s focus on its high-cost and high-needs enrollee populations, transform and streamline Medi-Cal managed care, extend components of a current federal waiver, and rethink how behavioral health services are financed and delivered.
