PROPOSED 2026 ACO UPDATES Shared Savings Program Participants

The 2026 CMS proposed rule introduces major updates for ACOs in the Medicare Shared Savings Program (MSSP), including mandatory APP reporting, a stronger push toward digital quality measures, and higher performance thresholds. Key changes also include revised benchmarking, beneficiary attribution adjustments, and expanded Promoting Interoperability requirements. ACO leaders should prepare for increased digital reporting demands while taking advantage of new flexibilities—especially for rural and smaller ACOs. Stay informed and ready for compliance ahead of the final rule.
