In-Network

In-network Co-payment
A fixed amount (for example, $15) you pay for covered health care services to providers who contract with your health insurance plan.  In-network copayments often cost less than out-of-network copayments.

Medically Necessary
Your insurance company makes suer that the health care you get is needed. If they think that the health care you get is not needed, they will not pay for it. You will have to pay for these services out-of-pocket.

Network 
A group of doctors, hospitals, and pharmacies that sign agreements with your insurance company to give you the best health care services possible.

Out-of-Network
Your provider does not have an agreement with this insurance plan and you may have no or little coverage with the network. Out-of-Network costs are always higher.

Out-of-Network Co-insurance
The percent (for example 40%) you pay of the allowed amount for covered health care services to providers who do not contract with your health insurance.  Out-of-network co-insurance often costs more than in-network co-insurance.

Out-of-Network Co-payment
A fixed amount (for example, $30) you pay for covered health care services from providers who do not contract with your health insurance. Out-of-network copayments often are more than in-network copayments.
