Healthcare financing refers to the methods and systems used to pay for medical services and treatments. This can include various sources such as government programs, private insurance, and out-of-pocket payments by individuals. The goal is to ensure that people can access necessary healthcare without facing financial hardship. Different countries have different healthcare financing models. For example, in the United States, many people rely on private insurance plans, while others may be covered by government programs like Medicare or Medicaid. In contrast, countries with universal healthcare systems often fund services through taxes, providing coverage for all citizens.
