Health insurance is a type of insurance coverage that pays for medical expenses. It helps individuals and families manage the costs of healthcare services, such as doctor visits, hospital stays, and prescription medications. By paying a monthly premium, policyholders can receive financial assistance when they need medical care. There are different types of health insurance plans, including employer-sponsored plans, government programs like Medicare and Medicaid, and private insurance options. Each plan has its own rules regarding coverage, costs, and networks of healthcare providers, making it important for individuals to choose a plan that best fits their needs.
