What is a common characteristic of health insurance plans?

Health insurance plans typically include elements such as premiums, deductibles, and co-pays, which are essential components of how these plans function financially. Premiums are the regular payments made to maintain coverage, while deductibles are the amount that policyholders must pay out-of-pocket before the insurance begins to cover costs. Co-pays are the fixed amounts that insured individuals pay for specific services or medications at the time of service.

This structure helps manage costs for both the insurer and the insured, making health care more accessible while also encouraging individuals to make more cost-conscious decisions regarding their health care usage. In contrast, the other options do not accurately reflect the common characteristics of health insurance plans and their associated costs and coverage.
