Participating provider organization
Participating provider organization means any arrangement in a third-party payer plan under which coverage is limited to services provided by a select group of providers who are members of the PPO or incentives (for example, reduced copayments) are provided for beneficiaries under the plan to receive health care services from the members of the PPO rather than from other providers who, although authorized to be paid, are not included in the PPO. However, a PPO does not include any organization that is recognized as a health maintenance organization.
