Yes, according to the information you provided, your father should get compensation, and the treatment fee should be paid by himself. Keep the invoice. If your father has agricultural medical insurance or social security, you can pay for it first, because both places need the original invoice to pay for it. At the same time, let him stamp you there and bring a copy of the invoice back to the insurance company for claim. You need to provide invoices, medical records, copies of ID cards, bank cards and insurance policies. You need to provide it if you are hospitalized. Your attitude is perfunctory, not afraid, as long as you can claim compensation. Your father is still in the treatment stage. Just report the case now. There is no need to make a claim in a hurry. If the treatment is over, you can provide complete claims information and ask them to give a time to settle claims, such as 7 working days. I wish your father a speedy recovery.
