In the United States, health insurance is any program that helps pay for medical expenses, whether through privately purchased insurance, social insurance or a social welfare program funded by the government.[1] Synonyms for this usage include "health coverage," "health care coverage" and "health benefits."
In a more technical sense, the term is used to describe any form of insurance that provides protection against the costs of medical services. This usage includes private insurance and social insurance programs such as Medicare, which pools resources and spreads the financial risk associated with major medical expenses across the entire population to protect everyone, as well as social welfare programs such as Medicaid and the State Children's Health Insurance Program, which provide assistance to people who cannot afford health coverage.
