Preferred provider organization
In health insurance in the United States, a preferred provider organization (PPO), sometimes referred to as a participating provider organization or preferred provider option, is a managed care organization of medical doctors, hospitals, and other health care providers who have agreed with an insurer or a third-party administrator to provide health care at reduced rates to the insurer's or administrator's clients.
Primary health organisation
A PHO is set up as a not-for-profit organisation with both community and provider representation. They maintain a list of their enrolled populations for which they get funding. PHOs include not just GPs and nurses, but also other health providers.
