When both you and your health insurance company pay part of your medical expense, it’s called cost sharing. Deductibles, coinsurance and copays are all examples. Understanding how they work will help you know when and how much you have to pay for care.
Deductible
A deductible is the amount you pay for health care services before your health insurance begins to pay.
Let's say your plan's deductible is $1,500. That means for most services, you'll pay 100 percent of your medical and pharmacy bills until the amount you pay reaches $1,500. After that, you share the cost with your plan by paying coinsurance and copays.
