On Jan. 1, 2025, the U.S. Center for Medicare & Medicaid Services’ (CMS) Innovation Center will begin implementing a payment model for primary care known as the Accountable Care Organizations (ACOs) Primary Care Flex Model under the Medicare Shared Savings Program (MSSP).
The ACO Flex Model is a voluntary initiative to improve funding and other resources to support primary care delivery within the MSSP. The model encourages the formation of new, physician-led ACOs, particularly those serving underserved communities and addressing health disparities.
This program is not just a test, but also seeks to empower participating ACOs and their primary care providers to employ more innovative, team-based, person-centered and proactive approaches to care.
