How do health insurance companies address the issue of moral hazard?

Health insurance companies address the issue of moral hazard primarily through cost-sharing measures such as copayments. Moral hazard refers to the tendency for individuals to take risks or utilize more healthcare services when they are insulated from the costs due to insurance coverage. By introducing mechanisms such as copayments, where policyholders pay a portion of the costs for services received, insurance companies encourage more responsible use of healthcare services. This not only helps to reduce unnecessary claims but also makes individuals more aware of the costs associated with their care, thereby promoting more judicious decision making regarding health services.

Cost-sharing effectively aligns the interests of the insured and the insurer, as it encourages patients to consider both the necessity and the appropriateness of the care they receive. This approach helps mitigate the tendency to overuse services that moral hazard can create when individuals do not bear any out-of-pocket expenses for their healthcare decisions.
