Final answer:
The patient with a 25% coinsurance for out-of-network providers would pay $125 for a $500 fee service from an out-of-network provider.
Step-by-step explanation:
When a patient has health insurance that includes both in-and out-of-network benefits, they need to be aware of the different payment structures for services rendered by providers within and outside their insurance network. In this case, a patient needs to pay a 25% coinsurance for out-of-network services. For a service with a $500 fee, this means the patient is responsible for paying 25% of the total cost of the service.
To calculate the amount the patient would pay for an out-of-network provider service, we use the following formula: Coinsurance percentage × Total service fee = Patient's payment.
Therefore: 0.25 × $500 = $125.
Thus, the patient would pay $125 for the $500 service if seen by an out-of-network provider.
