It's an automatic reimbursement, and you don't have to go to the human resources department to get it. The part exceeding 1800 will be automatically reimbursed by 70% as long as it is within the scope of medical insurance reimbursement. If the lower limit 1800 is reached, the outpatient expenses 100 yuan are all within the scope of reimbursement.
