About Us

The Medicare Shared Savings Program (Shared Savings Program) was established by section 3022 of the Affordable Care Act. The Shared Savings Program is a key component of the Medicare delivery system reform initiatives included in the Affordable Care Act and is a new approach to the delivery of health care. Congress created the Shared Savings Program to facilitate coordination and cooperation among providers to improve the quality of care for Medicare Fee-For-Service (FFS) beneficiaries and reduce unnecessary costs. Eligible providers, hospitals, and suppliers may participate in the Shared Savings Program by creating or participating in an Accountable Care Organization (ACO).

To fulfill the intent of the Affordable Care Act, the Shared Savings Program aims to improve beneficiary outcomes and increase value of care by providing:

  • Better care for individuals;
  • Better health for populations; and
  • Lowering growth in expenditures

The Shared Savings Program will reward ACOs that lower their growth in health care costs while meeting performance standards on quality of care and putting patients first. Participation in an ACO is purely voluntary.

What is an Accountable Care Organization (ACO)?

The Shared Savings Program ACOs are groups of doctors and other health care providers who voluntarily work together with Medicare to give high quality service to Medicare Fee-for-Service beneficiaries. An ACO is not a Medicare Advantage plan or an HMO.
