A patient must pay $500 per year for medical expenses before the insurance company will begin to cover any expenses. Which of the following terms describes this payment?

Coinsurance refers to the percentage of costs that a policyholder is responsible for after the deductible has been met. For example, if a plan includes a coinsurance of 20%, the insured pays that percentage of medical expenses after paying their deductible. Therefore, coinsurance is not applicable until after the deductible is satisfied.

A copayment, or copay, is a fixed dollar amount that the insured pays for specific services at the time of receiving care. Unlike a deductible, which is paid annually before any coverage begins, copayments are typically required for each visit or service, making it a different concept altogether.

Fee-for-service is a payment model where healthcare providers are paid for each service performed. This model contrasts with a deductible, as it does not involve a fixed annual payment that must be met before coverage starts. Instead, it focuses on the payment structure for services rendered.

A premium is the amount that an insured person pays regularly (usually monthly or annually) to maintain their health insurance coverage. This payment is separate from the deductible and does not influence the out-of-pocket costs for medical services incurred.
