Meeting the stipulated requirements to participate in the healthcare plan is the definition of eligibility, indicating that a person qualifies for the healthcare program or insurance.

Understanding the various components of health insurance, such as a deductible (an out-of-pocket expense before the insurance pays), the differences between fee-for-service and health maintenance organization (HMO) systems, and the issues related to adverse selection are critical in comprehending how healthcare systems operate and how policies can be structured to mitigate risks and provide effective coverage.
