The amount that must be paid for your health insurance or plan. You and/or your employer usually pay it monthly, quarterly or yearly.
The yearly amount you owe for health care services your health insurance or plan covers before your health insurance or plan begins to pay. For example, if your deductible is $1,000, your plan won’t pay anything until you have met your $1,000 deductible for covered health care services subject to the deductible.
A fixed amount (for example, $15) you pay for a covered health care service, usually when you get the service. The amount can vary by the type of covered health care service.
Your share of the costs of a covered health care service, calculated as a percent (for example, 20 percent) 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 percent would be $20. The health insurance or plan pays the rest of the allowed amount.
