If the child has no ID card, he can apply. Now the child has an ID number at birth, and the household registration book has the child's ID number. As long as it is insured, it can be reimbursed. Children without ID cards are ill and hospitalized, and the expenses incurred in the hospital should be paid in advance by themselves. After treatment, you should bring invoices, statements and other supporting materials issued by the hospital to the local social security center for reimbursement.
