ACO strategy this week centered on rising intermediary and actuarial infrastructure around CMS risk-based models: conveners are increasingly shaping MSSP participation, governance, and operational economics behind the scenes, while vendors such as Arbital Health are launching tools to model downside exposure under CMS’s ACO REACH program. The practical tension for VBC leaders is that Medicare shared-savings growth is becoming more capital- and risk-management intensive—especially as stakeholders weigh stop-loss structures, benchmark volatility, and specialty models like Kidney Care Choices, where Interwell Health reported savings and high quality scores.
