Introduced
Summary
Count primary care services by certain ACO (accountable care organization) clinicians when assigning Medicare beneficiaries.

Show full summary
- Medicare beneficiaries: Assignment could shift to reflect who provides a beneficiary's primary care, which may change which ACO is responsible for coordinating their care.
- ACOs: Accountable care organizations could see their attributed patient panels change because qualifying primary care visits would be added as a basis for assignment.
- Primary care clinicians: Clinicians who meet the definition in 1899(h)(1)(B) would directly determine assignment through the primary care services they furnish, making those visits central to ACO attribution.
