Launched in 2012 as one of the nation’s first accountable care organizations, OSF HealthCare ACO was later selected as one of the original 18 “next generation” ACOs and has participated in the Medicare Shared Savings Program since 2017. With a network of more than 2,200 clinicians across over 170 locations, OSF managed more than 1 million patient encounters in 2024 and currently serves over 45,000 Medicare beneficiaries. By coordinating care among primary and specialty physicians, mid-level clinicians, care management, pharmacy, analytics, IT and executive leadership, OSF delivers high-quality, cost-effective services that improve population health. These efforts have led to major Medicare savings, including more than $52 million in 2020 and 2021. In 2022, OSF saved $35 million over CMS benchmarks and earned a $25.9 million payback. In 2023, it saved nearly $40 million and received $29.2 million. All paybacks are reinvested into patient care. In 2025, OSF HealthCare launched a reorganization of population health activity to drive clinical excellence, value-based care, data analysis and community outreach even further.
