Members of America’s Physician Groups (APG) are among the accountable care organizations (ACOs) that continue to produce top quality results and financial savings in the Medicare Shared Savings Program (MSSP), based on 2024 results released this week by the Centers for Medicare & Medicaid Services (CMS). For Performance Year (PY) 2024, the 476 ACOs now in MSSP achieved the highest savings since the program’s inception, earning shared savings payments totaling $4.1 billion, and producing $2.4 billion in net savings for Medicare relative to spending benchmarks.
“APG is proud of our 31 member organizations, which collectively operate 45 MSSP ACOs, for achieving these important performance incentives and net savings for the nation’s taxpayers,” said Susan Dentzer, APG’s President and Chief Executive Officer. She noted that physician-led ACOs continued to outperform so-called “high revenue” ACOs that are typically hospital-led, and that ACOs composed predominantly of primary care clinicians performed better compared to those with fewer primary care clinicians. “Our ACO members typically channel their shared savings back into building their capacities and infrastructure to achieve accountable care, thus keeping the ‘flywheel’ of performance improvement in traditional Medicare going,” Dentzer said.
Overall, MSSP ACOs had higher savings per capita in 2024 compared to 2023, demonstrating that savings are continuing to grow over time as ACOs become more efficient in delivering care at a lower cost. In addition to financial savings, nearly all ACOs continued to meet and exceed quality standards. Multiple quality measures showed that ACOs demonstrated improvements in beneficiaries with adequately controlled high blood pressure, declines in poor hemoglobin A1c control, and increases in screenings and follow-ups for depression among Medicare enrollees.
APG will continue to evaluate the results and determine precisely how much in net and shared savings and quality improvements its members contributed. Meanwhile, APG salutes its participating organization members, which include the following:
