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.

Participation waiver disclosure

  • No, our ACO does not use the SNF 3-Day Rule Waiver.

The Secretary of the U.S. Department of Health and Human Services has provided waivers of certain federal fraud and abuse laws that may otherwise limited innovation by ACOs participating in the Medicare Shared Savings Program (“MSSP”). See Final Waivers in Connection With the Shared Savings Program, 79 Fed. Reg. 62356 (Oct. 17, 2014) (“Interim Final Rule”). Pursuant to the Interim Final Rule, North Shore-LIJ MSSP ACO, Inc. (the “ACO”) seeks waiver protection for the arrangement described below:

The ACO has entered into an agreement with Northwell Health to provide a broad range of necessary management services and operational personnel to support the ACO’s operations as an ACO in the MSSP. Under the arrangement, the ACO shall compensate Northwell Health from any shared savings payments for its provision of management services, including but not limited general day-to-day operational personnel and services, financial management and accounting services, and credentialing.

The ACO’s governing body, consistent with its obligations under 42 C.F.R. § 425.106(b)(3), has made and duly authorized a bona fide determination on August 23, 2016 that the arrangement is reasonably related to the purposes of the Medicare Shared Savings Program, including, specifically, promoting accountability for the quality, cost, and overall care for a Medicare population and aiding the ACO in managing and coordinating care for Medicare fee-for-service beneficiaries.
