About the ACO

WellStar Health Network has been selected to participate in the Medicare Shared Savings Program (Shared Savings Program) Accountable Care Organization (ACO), a multifaceted new program sponsored by the Centers for Medicare and Medicaid Services (CMS). Through the Shared Savings Program, WellStar Health Network will work with CMS to provide Medicare fee-for-service beneficiaries with high quality service and care, while reducing the growth in Medicare expenditures through enhanced care coordination.

The WellStar ACO was formed as a partnership between hospitals and ACO professionals.

How ACOs Work

Local health care providers and hospitals volunteer to work together to provide you with coordinated care. The doctors and other providers who are helping care for you will communicate with each other, and partner with you in making health care decisions. Your doctors use data from Medicare to help improve how they provide care. For example, your doctors will obtain your medical information from Medicare including your medical history, medical conditions, prescriptions, and visits to the doctor in order to give you the right care at the right time in the right setting.

You’ll likely have fewer repeated medical tests because your doctors and hospitals will share information and coordinate your care. Your care providers will be paid partly based on providing improved care, improved coordination, and improved value—not just more tests and procedures.

If beneficiaries choose not to share their medical information, they may contact CMS at 1-800-MEDICARE.
