Initiative builds on the success of MSSP that helped beneficiaries and saved billions for Medicare
Washington, D.C., March 19, 2024 — Today the Centers for Medicare & Medicaid Services (CMS) Innovation Center introduced ACO Primary Care Flex, a new accountable care organization model, to provide incentives for health care providers to transition from fee-for-service delivery to accountable care models that prioritize patient care and outcomes. Accountable for Health (A4H) CEO Mara McDermott issued the following statement:
“The CMS Innovation Center’s new ACO Primary Care Flex model is a positive step to expand access to effective accountable care across the country. This model will deploy prepayment for primary care services, accelerating the movement away from our health system’s reliance on a costly volume-based fee-for-service reimbursement system. This new model will wrap around the existing Medicare Shared Savings Program, which has demonstrated success in terms of cost savings and care improvements – saving $1.8 billion in traditional Medicare, and $3.6 billion when you account for spillover effects in Medicare Advantage—all while producing meaningful quality improvements for Medicare beneficiaries. Offering new models like this is essential to help us reach the bipartisan goal of 100 percent participation in accountable care across Medicare.”
