What is an ACO?

Accountable Care Organizations (ACOs) are groups of doctors, hospitals, and other health care providers, who come together voluntarily to give coordinated high quality care to their Medicare patients.  The goal of coordinated care is to ensure that patients, especially the chronically ill, get the right care at the right time, while avoiding unnecessary duplication of services and preventing medical errors.  When an ACO succeeds both in delivering high-quality care and spending health care dollars wisely, it will share in the savings it achieves for the Medicare program.  Also, please visit the following website:
