ACO Assignment Improvement Act of 2025
To amend title XVIII of the Social Security Act to improve the way beneficiaries are assigned under the Medicare shared savings program by also basing such assignment on primary care services furnished by nurse practitioners, physician assistants, and clinical nurse specialists.
Summary
The bill modifies Medicare's shared savings program to expand how patients are assigned to accountable care organizations (ACOs). Starting January 1, 2026, primary care services provided by nurse practitioners, physician assistants, and clinical nurse specialists will count toward patient assignment, alongside services from other providers. This broadens the range of healthcare professionals whose services can determine an ACO's assigned patient population. The change amends Section 1899(c)(1) of the Social Security Act.
