Policy Snapshot

March 22, 2024

On March 19, the Department of Health & Human Services (HHS), through the Centers for Medicare & Medicaid Services (CMS), announced a new voluntary model that empowers primary care providers in eligible Accountable Care Organizations (ACOs) to treat people with Medicare using innovative, team-based, person-centered proactive care. A key part of the Biden-Harris Administration’s efforts to further promote competition in health care, the ACO Primary Care Flex Model (ACO PC Flex Model) will provide a one-time advanced shared savings payment and monthly prospective primary care payments (PPCPs) to ACOs. The advanced shared savings payments provide ACOs with needed resources and flexibility to cover costs associated with forming an ACO (where relevant) and administrative costs for required model activities. PPCPs will be distributed by ACOs to primary care practices, giving them improved resources and flexibility to provide care that best suits individuals’ needs. 

The ACO PC Flex Model is a five-year voluntary model that will begin on January 1, 2025. CMS is planning to select approximately 130 ACOs to participate in the model. Organizations interested in participating must first apply—either as new ACOs or renewing ACOs—to the Shared Savings Program. Shared Savings Program Applications are open May 20-June 17, 2024. The ACO PC Flex Model Request for Applications is scheduled to be released in the second quarter of 2024.
