The medical insurance center is the office of medical insurance, which is responsible for the specific handling work, including the medical insurance management of individuals and units. They are led by the medical insurance department and also managed by the Human Resources and Social Security Bureau. The medical insurance center has great power in the process of handling medical insurance affairs, including reviewing and paying medical expenses, managing medical insurance funds, and formulating medical insurance policies. The medical insurance bureau is the manager and supervisor of the medical insurance fund, responsible for supervising the operation and management of the medical insurance center, as well as the formulation and adjustment of medical insurance policies. The role of medical insurance bureau in the medical insurance system is more inclined to supervision and management, which plays a greater role in guiding and supervising medical insurance centers, but has less power in specific handling work.
