At present, medical insurance cards cannot be used in other places. If you encounter an emergency in the workplace, you can go to the local medical insurance designated hospital for medical treatment, pay the expenses first, and then go to the medical insurance for reimbursement. You can't do this if it's not an emergency. If you are an employee who has been overseas for a long time, you can ask the unit to apply for relocation from the local medical insurance, and choose 1 to go to two designated hospitals in the workplace, so that it can be treated as an emergency, and you can apply for reimbursement first.
