ACO Assignment Improvement Act of 2025

The ACO Assignment Improvement Act of 2025 modifies Medicare's Shared Savings Program to change how beneficiaries are assigned to Accountable Care Organizations (ACOs). Starting in 2026, beneficiaries receiving primary care services from specific ACO doctors will automatically be counted toward the ACO's performance metrics. This adjustment directly affects Medicare beneficiaries enrolled in ACOs and the ACOs themselves, as it clarifies which patient assignments count toward their program goals. The change streamlines the assignment process for primary care services under Medicare, aiming to improve how ACOs are measured for shared savings. The bill does not alter Medicare benefits or costs but refines the administrative rules for ACO participation.
