What does a health insurance policy usually outline?

A health insurance policy is a detailed contract that outlines the specific coverage and benefits provided to the insured. This includes essential information such as the covered services, exclusions, limitations, and the conditions under which benefits will be paid. By defining what is included and what is not, it ensures that both the insurer and the insured have a clear understanding of the terms of coverage. This clarity helps policyholders know what type of medical expenses they can claim and under what circumstances, making option B the most accurate representation of what a health insurance policy typically details.

The other options fail to encapsulate the integral components of a health insurance policy. While the cost of premiums is indeed a part of the policy, it does not encompass the essential benefits or coverage details that the policy provides. Historical data on the insurer, although potentially relevant for understanding company performance, does not pertain to the individual policy terms. Lastly, an individual's income information is typically not related to the coverage specifics outlined in health insurance policies; rather, it might be considered during eligibility assessments for financial aid or subsidies, but it does not belong in the policy's core details. Thus, the correct answer emphasizes the importance of understanding what kind of healthcare services are covered and the associated limitations.
