Hello, where can I open the split sheet? Why did you go to the medical insurance office? They say there is no such thing.

Insurance companies can open split documents, and the expense reimbursement details issued by social security are called approval documents.

Which city are you from? At present, medical insurance cards are generally used to settle accounts, and there is no need to run social security. Note: Generally, social security reimbursement requires original bills, and then you can take the reimbursement list (approval form) stamped by social security and copies of all receipts, medical records and inspection reports to the commercial insurance company for reimbursement.

Be sure to make a copy of what you see before taking it to social security for reimbursement, because it is very troublesome to find a copy of social security, and it is generally not adjusted.
