Meritage Accountable Care Organization (ACO)

In January 2013, Meritage Medical Network was designated as an Accountable Care Organization (ACO) by Medicare. One of the most publicized facets of the Affordable Care Act, ACOs seek to provide quality care while keeping costs low. With 55 percent of the US population living within an area serviced by 227 ACOs, it’s important for anyone seeking out a healthcare provider to understand how this program works.

An ACO is a network of healthcare providers that share responsibility and work collaboratively to provide care for a group of patients. For all patients, an ACO is designed to improve quality of care and reduce costs. Intended to hold providers jointly accountable for the health of their patients, there is a strong incentive for cooperation and avoidance of unnecessary tests and procedures. For Medicare patients, ACOs create opportunities for better quality of healthcare. Putting the patient at the center of care, doctors will be better able to keep them informed, listen to their needs and helping them to make the right decisions for their health.

While designed to be a flexible healthcare model, in general ACOs should:

● Possess sufficient infrastructure and management to support comprehensive care

● Share information seamlessly between providers in the network for the benefit of the patients and providers

● Utilize health information technology to manage patients across the continuum of care and within different institutional settings.

Cost savings anticipated by the Congressional Budget Office are projected at approximately 5.3 billion during 2010-2019. However, the true value of an ACO lies in the improvement of our healthcare system. Insuring accountability by quality performance measures such as care coordination, patient safety, and appropriate use of preventive health services ACOs are a step towards managing our healthcare dollars and delivering effective quality care to all Americans.
