CalAIM 1115 Demonstration & 1915(b) Waiver
Return to CalAIM Homepage
California received federal authority necessary to implement California Advancing and Innovating Medi-Cal (CalAIM), a framework that encompasses broad-based delivery system, program, and payment reform across the Medi-Cal program. CalAIM is an innovative and long-term commitment to transform and strengthen Medi-Cal, making the program more equitable, coordinated, and person-centered to help people maximize their health and life trajectory. CalAIM shifts Medi-Cal to a population health approach – first included in the Medi-Cal 2020 Section 1115 demonstration – to a statewide level that prioritizes prevention and addresses social drivers of health. Collectively, the CalAIM Section 1115 demonstration and CalAIM Section 1915(b) waiver, along with related contractual and Medi-Cal State Plan Amendments, will enable California to fully execute CalAIM initiatives, providing person-centered care to integrate care coordination across physical health, behavioral health, and local service providers.
Since 2018, DHCS has been working closely with stakeholders to design a transformation of key aspects of the Medi-Cal delivery system in order to accomplish three primary goals:
-
Identify and manage comprehensive needs through whole person care approaches and social drivers of health;
-
Make Medi-Cal a more consistent and seamless system for enrollees to navigate by reducing complexity and increasing flexibility; and
-
Improve quality outcomes, reduce health disparities, and transform the delivery system through value‑based initiatives, modernization, and payment reform.
In 2019 and early 2020, DHCS conducted extensive stakeholder engagement for the proposed CalAIM initiatives. CalAIM implementation was scheduled to begin in January 2021, but was delayed due to the impact of the COVID-19 public health emergency. On December 29, 2020, DHCS received approval from the Centers for Medicare & Medicaid Services (CMS) for a 12-month extension (through December 31, 2021) of the existing Medi-Cal 2020 Section 1115 demonstration. DHCS submitted two requests in June 2021 to CMS: (1) the CalAIM Section 1115 demonstration (formerly entitled Medi-Cal 2020 Section 1115 demonstration) for a five-year renewal, with amendment; and (2) the CalAIM Section 1915(b) waiver for a five-year renewal, with amendment. DHCS received approval on December 29, 2021 for both the demonstration and waiver, effective through December 31, 2026. DHCS and CMS continue to work toward additional approvals for equity-oriented CalAIM initiatives in the state's Section 1115 demonstration requests – including services and supports for justice involved adults and youth, and reimbursement for traditional healers and natural helpers. CMS approval of these waivers is anticipated in early 2022 and materials will be updated accordingly.
