ACO Assignment Improvement Act of 2025

The bill, titled the ACO Assignment Improvement Act of 2025, proposes changes to how beneficiaries are assigned to Accountable Care Organization (ACO) arrangements under Medicare’s Shared Savings Program (MSSP). Specifically, it would add a new provision to require that, for performance years starting on or after January 1, 2027, primary care services provided by ACO professionals identified in the MSSP be treated in a way that affects beneficiary assignment. In short, the bill aims to better align beneficiary attribution with the primary care work done by ACOs. The document provided also references establishing a SNF-at-home program under Medicare in the title, but the text excerpt here only contains the MSSP assignment change and does not include substantive SNF-at-home program details.
