According to China's medical insurance system, the maximum outpatient expenses that employees can pay for medical insurance are 20,000 yuan, and the maximum hospitalization expenses are 300,000 yuan. If the medical expenses that should be reimbursed exceed the prescribed limit of the employee medical insurance pooling fund, the medical insurance pooling fund will not pay. This is to ensure the rational use of medical insurance funds and prevent excessive medical care and waste of medical resources.
