In 2015, the Northwell Health ACO chose to participate in the Medicare Shared Savings Program, with an effective start date of January 1, 2016. The Northwell Health ACO is governed by independent physicians, Northwell Health employed physicians, and a Medicare FFS beneficiary.

Northwell Health’s participation in the Medicare Shared Savings Program presents an opportunity to develop innovative approaches to health care delivery, streamline existing value-based programs, and promote wellness that will improve the health of our communities.

What is a Medicare Shared Savings Program ACO?

A Medicare Shared Savings Program (MSSP) Accountable Care Organization (ACO) is a new, national approach to health care delivery for Medicare fee-for-service (FFS) beneficiaries. Created under the 2010 Patient Protection and Affordable Care Act, a MSSP ACO works to improve quality and reduce unnecessary costs.

MSSP ACOs are not managed care organizations, do not use closed networks of providers, and do not limit a Medicare beneficiary’s ability to seek care from participating Medicare providers outside an ACO.

There is no financial downside risk or disruption to underlying Medicare fee-for-service billing. When an MSSP ACO succeeds both in delivering high-quality care and spending health care dollars more wisely, it will share in the savings it achieves for the Medicare program.

For general questions or additional information about Accountable Care Organizations, please visit or call 1-800 MEDICARE (1-800-633-4227) TTY users should call 1-877-486-2048.
