A co-pay is a fixed out-of-pocket amount paid by an insured for covered services. It
is a standard part of many health insurance plans. Your co-pay may vary based on
the type of visit (office visit vs hospital visit).

The amount you could owe during a coverage period (usually one year) for health
care services your health insurance or plan covers before your health insurance or
plan begins to pay.

Your out-of-pocket costs (copayments, coinsurance and deductibles) show the
most money you will have to pay for covered services in a plan year. Some items
and services will not count toward that maximum.

Your share of the costs of a covered health care service, calculated as a percent (for
example, 20%) of the allowed amount for the service. You pay coinsurance plus any
deductibles you owe. For example, if the health insurance or plan’s allowed amount
for an office visit is $100 and you’ve met your deductible, your coinsurance payment
of 20% would be $20. The health insurance or plan pays the rest of the allowed
amount.
