Preferred Provider Organization (PPO)

arrangement, insured or uninsured, where contracts are established by Health Plan Companies (typically, commercial insurers, and, in some circumstances, by self-insured employers) with health care providers. The Health Plans involved will often designate these contracted providers as "preferred" and will provide an incentive, usually in the form of lower deductibles or co-payments, to encourage covered individuals to use these providers. Members are allowed benefits for non-participating provider services on an indemnity basis with significant copayments and providers are often, but not always, paid on a discounted fee for service basis.
