Health care financing refers to the methods and systems used to pay for medical services and treatments. This can include various sources such as private insurance, government programs like Medicare and Medicaid, and out-of-pocket payments by patients. Effective health care financing ensures that individuals can access necessary medical care without facing financial hardship. Different countries have different health care financing models. For example, some nations use a single-payer system, where the government funds health care for all citizens, while others rely on a mix of private and public funding. Understanding these systems is crucial for improving health care access and quality.
