ACCOUNTABLE CARE ORGANIZATION (ACO)

Back to Glossary

Definition

A group of providers that coordinate patient care to improve quality and lower costs; payment is tied to performance.


Summary

An Accountable Care Organization (ACO) is a healthcare delivery model where different healthcare providers (doctors, hospitals, specialists, etc.) work together as a team to coordinate all aspects of a patient's care. Think of it as a healthcare 'team approach' where everyone communicates and collaborates to ensure patients get the right care at the right time, while avoiding unnecessary duplicate tests or treatments. The key innovation is that these provider groups are financially rewarded when they successfully improve patient health outcomes while keeping costs reasonable, rather than being paid simply for the volume of services provided.

Usage Context

Understanding ACOs is crucial when studying healthcare delivery models, payment reform initiatives, quality improvement strategies, and the shift from volume-based to value-based healthcare systems. This concept is particularly important in health policy, healthcare administration, and discussions about controlling healthcare costs while improving outcomes.

Common Confusions

  • Thinking ACOs are the same as HMOs or insurance plans (ACOs are provider organizations, not insurers)
  • Believing patients must enroll in or choose an ACO (often patients are automatically attributed based on where they receive primary care)
  • Assuming ACOs only serve Medicare patients (while Medicare ACOs are common, there are also commercial and Medicaid ACOs)
  • Confusing ACOs with hospitals (ACOs are networks that can include multiple hospitals, clinics, and individual providers)
