Most health insurance plans will set something called an allowable cost. That’s the amount that the insurance is willing to cover for a certain procedure, service, or test. The allowable cost may not be the full amount that the doctor is billing for. This means you may need to pay the difference.

Have questions about an allowable cost for a particular procedure? Check with your insurance before you schedule a service.
