At present, the method of reimbursement for surgical social security is to bring a card when you are in hospital. When you are in hospital, you only need to pay part of it yourself, and you don't have to worry about the part of social security reimbursement. The social security bureau will give the money to the hospital, and the money in your card will not be deducted. If you don't have a card, you need a hospital admission certificate, a list of expenses, an invoice and an outpatient service.
