Health insurance is a financial arrangement that provides individuals with coverage for medical expenses. Policyholders pay regular premiums to an insurance company, which then helps cover the cost of healthcare services, including doctor visits, hospital stays, prescription medications, and preventive care. Health insurance can protect individuals and families from the financial burden of unexpected medical bills and ensure access to necessary healthcare. It comes in various forms, such as private plans, employer-sponsored coverage, and government programs like Medicare and Medicaid, offering a range of benefits and costs. Health insurance plays a crucial role in promoting healthcare access and financial security for many individuals.
