ACO Assignment Improvement Act of 2015
This bill amends title XVIII (Medicare) of the Social Security Act to establish additional requirements for assigning Medicare fee-for-service beneficiaries to accountable care organizations (ACOs) under the Medicare shared savings program. (The program enables ACOs to receive payments for savings stemming from care coordination and management.)
Specifically, 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. Other ACO practitioners include physician assistants, nurse practitioners, clinical nurse specialists, certified registered nurse anesthetists, certified nurse-midwives, clinical social workers, clinical psychologists, and registered dieticians or nutrition professionals.
