Accountable Care Organization

Northwestern Medicine has two Accountable Care Organizations (ACOs). Our participation in the Medicare Shared Savings Program (MSSP) recognizes our ability to work together with CMS and participating physicians to provide high-quality service to our Medicare Fee-for-Service beneficiaries, ensuring they receive the right care at the right time in the right setting. As an organization, we work closely with physicians and other healthcare providers participating in the ACOs to promote seamless, coordinated care.

Northwestern Medicine Physician Network ACOs help providers to track a Medicare Fee-for-Service beneficiary’s services across multiple care settings to ensure that each healthcare provider who has a role in a Medicare Fee-for-Service beneficiary’s care can have a complete picture—providing an improved care experience for each patient. This section describes important information for the public about the Northwestern Medicine Physician Network ACOs.
