National Health Insurance (NHI) is a system where the government provides health coverage to all citizens, ensuring access to medical services without direct payment at the time of care. This approach aims to reduce financial barriers to healthcare, promoting overall public health and well-being. Under NHI, funding typically comes from taxes or contributions, allowing for a more equitable distribution of healthcare resources. It often covers a range of services, including hospital visits, preventive care, and prescription medications, helping to ensure that everyone receives necessary medical attention regardless of their financial situation.
