The Centers for Medicare & Medicaid Services (CMS) revealed several updates to the ACO REACH program in 2026, though the model’s long-term future remains unclear.
The CMS said it is making changes to the model based on preliminary data on 2023 performance, which found that standard accountable care organizations saved $197.5 million in aggregate that year. New entrant ACOs, meanwhile, generated $36.8 million in aggregate savings, reducing gross spending at higher rates that standard organizations.
In addition, high-needs ACOs reduced spending by $2.3 million in the aggregate, according to the preliminary report. The CMS is set to release full data on ACO REACH later this year.
