Under what circumstances can the medical insurance card of Guizhou college students be reimbursed?

Looking through the student handbook: according to the regulations, college students implement the first diagnosis system. When students go to the hospital for medical treatment, they only need to pay 40% of all medical expenses with their social security cards, student ID cards and medical records. Students from other hospitals can apply for a corresponding proportion of medical expenses at the school's free medical service with social security cards, referral certificates issued by the school hospital, medical records and invoices from other hospitals. For example, 50% of the total expenses can be reimbursed for seeing a doctor in Huaxi District Hospital, and 40% of the total expenses can be reimbursed for seeing a doctor in a tertiary hospital (the registration fee is paid at one's own expense), and each reimbursement fee does not exceed 300.00 yuan (referring to the part returned to the students).
