For Professionals

Montefiore Accountable Care Organization

The Montefiore Pioneer Model Accountable Care Organization (ACO) is a program that provides certain beneficiaries of the original Medicare program access to enhanced care coordination programs and a focus on illness prevention and wellness.

Montefiore's experience coordinating care for patients across multiple care settings led to its designation by Medicare in 2011 as a Pioneer ACO—one of only 32 organizations in the nation and the only one in New York State. The Pioneer ACO program is designed to test new models of healthcare delivery and payment and provide Medicare beneficiaries with higher quality care, while reducing expenditures through enhanced care coordination.

In addition to Montefiore's three adult hospitals, its extensive primary care and specialty sites and its employed and affiliated community-based physicians, the Montefiore ACO includes providers from other healthcare organizations in the Bronx, Brooklyn and Staten Island.
