On December 28, 2021, California secured the authority it needed from the Centers for Medicare & Medicaid Services (CMS) to fully execute its larger CalAIM initiative, which provides benefits to certain high-need, hard-to-reach populations identified by DHCS, with the objective of improving health outcomes for Medi-Cal beneficiaries. CMS granted authority based on successful prior programs, including Whole Person Care Pilots, the Drug Medi-Cal Organized Delivery System and Specialty Mental Health Services.
