The Accreditation Association for Ambulatory Health Care, also known as AAAHC or the Accreditation Association, is a private, nonprofit organization formed in 1979. It is a leader in developing standards to advance and promote patient safety, quality and value for ambulatory healthcare through peer-based accreditation processes, education and research. Accreditation is awarded to organizations that are found to be in compliance with the Accreditation Association standards.

The Accreditation Commission for Health Care offers Ambulatory Care Accreditation for medical care provided on an outpatient basis, including diagnosis, observation, treatment, intervention and rehabilitation services. As an internationally recognized accreditation organization with 30-plus years of experience, ACHC offers a collaborative survey approach and relevant standards designed to empower providers to enhance patient care.
