Effective April 1, 2012, a new program similar to ADHC – CBAS – began under California’s "Bridge to Reform" 1115 Medicaid waiver (known as the Medi-Cal 2020 1115 Waiver). CBAS is a
community-based day health program that provides services to older persons and adults with chronic medical, cognitive, or mental health conditions and/or disabilities that are at risk of
needing institutional care. The purpose is to delay or prevent institutionalization and maintain individuals in their homes and communities for as long as possible.
Former ADHC participants who met the more stringent CBAS eligibility standards began receiving CBAS services in approved CBAS centers on April 1, 2012. As of December 2024, there are 303
CBAS centers statewide. In addition to meeting Medi-Cal program and waiver requirements, CBAS providers must maintain an ADHC license.
Under an interagency agreement, the CBAS Program is administered among the Department of Health Care Services (DHCS), the CDPH, and the California Department of Aging (CDA). CDA
certifies licensed ADHC centers as Medi-Cal CBAS providers.
CDA is responsible for initial certification of new CBAS centers as Medi-Cal providers, certification renewal, providing ongoing training and technical assistance to centers,
and initiating adverse certification actions against centers that are substantially out of compliance with program requirements.
