국민건강보험 is a public health insurance system in South Korea that provides coverage for medical expenses to all citizens. Established in 1977, it aims to ensure that everyone has access to necessary healthcare services, regardless of their financial situation. The system is funded through contributions from both employers and employees, as well as government subsidies. Under 국민건강보험, individuals can receive a range of medical services, including hospital visits, surgeries, and preventive care. The insurance covers a significant portion of medical costs, making healthcare more affordable for the population. This system plays a crucial role in promoting public health and improving the overall well-being of South Koreans.
