Which of the following is NOT an example of cost sharing in a health insurance policy?

Coinsurance is a form of cost sharing where the insured pays a certain percentage of the costs of a covered healthcare service after the deductible has been met. For example, if a policy has a coinsurance rate of 20%, the insured is responsible for paying 20% of the medical costs, while the insurance company covers the remaining 80%. This mechanism directly involves the insured in sharing the costs of their healthcare.

A copayment, or copay, is a fixed amount that the insured pays for a specific service at the time of receiving care, such as a doctor's visit or prescription medication. This is a direct example of cost sharing, as it represents an out-of-pocket expense incurred by the insured for accessing healthcare services.

A deductible is the amount that the insured must pay out-of-pocket before the insurance begins to cover costs. Once the deductible is met, the insurer typically pays a larger share of the costs, making it a significant form of cost sharing between the insurer and the insured.
