College students who live outside the overall planning area during holidays, suspension from school and the educational practice, project research and social investigation stipulated by the school and need hospitalization or intensive outpatient treatment should register with the medical insurance agency through the medical security management department of the students at school and choose the designated medical institution for medical treatment. The medical expenses incurred should be paid in full by the individual first, and then the reimbursement procedures should be handled after medical treatment.

If it is necessary to transfer the medical treatment outside the overall planning area, it should provide the consultation opinions of the chief physicians of medical institutions at or above the provincial level, and send them to the medical insurance center for examination and approval after referral. The expenses shall be paid in full by the institution or the students themselves, and 1 and medical insurance card shall be presented after medical treatment; 2. Expense documents and lists (stamped with the official seal of the hospital or charging unit); 3, residents, short doctor's advice and discharge summary (copy stamped with the official seal of the hospital); 4. Checklist of hospitalization; 5. My settlement account of China Agricultural Bank goes through the reimbursement procedures in the municipal medical insurance center.

I'm afraid you didn't inform the school in advance.

And some operations and diseases are not covered by insurance, such as plastic surgery and so on.
