Connected Care of Southeastern Massachusetts

Next Generation ACO

On February 27, 2019, Connected Care of Southeastern Massachusetts submitted to the Centers for Medicare & Medicaid Services a notice of intent to voluntarily terminate participation in the Next Generation ACO Model Program. Termination is effective at 11:59 p.m., March 28, 2019.


Connected Care of Southeastern Massachusetts is a Next Generation Accountable Care Organization (ACO) for Medicare beneficiaries established by South Shore Health in collaboration with Brigham and Women’s Harbor Medical Associates. A Next Generation ACO is implemented through CMS’ Centers for Medicare and Medicaid Innovation (CMS Innovation Center). ACOs are a group of doctors, hospitals, and other health care providers that come together to provide high quality, coordinated care to their Medicare fee-for-service beneficiaries.


If your physician is participating in Connected Care of Southeastern Massachusetts, you should have received a welcome letter. As a Next Generation ACO beneficiary, your primary care physician and specialists will work together to create a treatment plan that addresses your specific health care needs. By working closely together to coordinate your care, your physicians and other health care providers can more effectively help you stay well and improve your overall health.


Your doctor’s participation in our Next Generation ACO does not change anything about your Medicare benefits and does not restrict the doctors you can choose to see. All of the benefits you currently receive under Medicare remain the same.

How Shared Savings are Distributed

The ACO’s governing board will determine a methodology for the sharing of savings if and when any gains are achieved. Connected Care of Southeastern Massachusetts has not received any Shared Savings payments to date. If we are able to receive any financial gains from this ACO initiative in the future, these gains would be used to cover the costs that we have already incurred and to support ongoing healthcare delivery.
