Key: what the circles and colors mean
Each circle is a bill. The ring fills as it moves through Congress:
Under the number: the Yea · Nay count of its final (or latest) recorded vote. On a member's page, the small badge is how that member voted: Y Yea / Aye, N Nay / No, P Present, – Not voting.
Gold and violet are only for Yea and Nay; they never mean a party. A member's party is the letter on their photo.
Not yet voted on. This bill is still a proposal: it hasn't reached a floor vote, and its text can change in committee or on the floor before any vote.

ACO Assignment Improvement Act of 2025
This bill establishes additional requirements for assigning Medicare fee-for-service beneficiaries to accountable care organizations (ACOs) under the Medicare shared savings program. Under current law, the program enables ACOs to receive payments for savings stemming from care coordination and management.
The bill requires the basis for assignment to reflect beneficiaries' utilization of not only primary care services provided by ACO physicians, but also those provided by other ACO practitioners—specifically, physician assistants, nurse practitioners, and clinical nurse specialists.
