NCQA's Preferred Provider Organization (PPO) Accreditation Program provides consumers, employers and others with information about the quality of the nation's preferred provider organizations. PPOs collectively cover more than 100 million Americans, making it critical that objective, comprehensive information about PPO quality be made available. NCQA's PPO Accreditation program includes a rigorous review against standards in the areas of access, service and qualified providers. In addition, PPOs must measure and report on their customers’ experiences and satisfaction in key areas such as access to care, claims payment and customer service.
