Out-of-network, also called out-of-plan or non-preferred provider
Most health plans have a list of doctors, hospitals, and other providers that have agreed to participate in the plan’s network. Providers in the network have a contract with your plan to care for its members at a certain cost. You pay less for medical services when you use one of the providers on this list.
If you see a doctor or use a hospital that does not participate with your health plan, you are going out-of-network. You usually have to pay more for out-of-network care. Some plans won’t cover any amount of out-of-network care. Some cover a percentage of care.
