If a work-related injury cannot be covered by medical insurance, it must be reimbursed by the Social Security Bureau at its own expense, and then by invoices and medical records. If the expenses required for work-related injury treatment meet the catalogue of work-related injury insurance diagnosis and treatment items, the catalogue of work-related injury insurance drugs and the hospitalization service standard of work-related injury insurance, they shall be paid from the work-related injury insurance fund. There are many analogies to C, and some C can also be reimbursed.
