A copay is a fixed out-of-pocket amount paid by an insured for covered services. It is a standard part of many health insurance plans. Insurance providers often charge co-pays for services such as doctor visits or prescription drugs.
Copays are a specified dollar amount rather than a percentage of the bill, and they are paid at the time of service. Not all medical services ask you for a copay. For example, some insurance companies do not require a copay for annual physicals/well child visits.
The 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 $1000, your plan won't pay anything until you've met your $1000 deductible for covered health care services subject to the deductible. The deductible may not apply to all services.
The most you pay during a policy period (usually a year) before your health insurance or plan begins to pay 100% of the allowed amount. This limit never includes your premium, balance-billed charges or health care your health insurance or plan doesn’t cover. Some health insurance or plans don’t count all of your co-payments, deductibles, coinsurance payments, out-of-network payments or other expenses toward this limit.
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.
