A co-pay increases risk for the insured because they will have to pay the amount of the co-pay every time they visit the service provider. This financial responsibility can increase the cost of healthcare for the insured and may act as a barrier to seeking care, particularly if the co-pay is high. The insurer's risk is mitigated by the co-pay, as it limits the amount that the insurer has to pay for each visit. Therefore, the correct response is:
A co-pay increases risk for the insured because they will have to pay the amount of the co-pay every time they visit the service provider.
