Can I use a medical insurance card for hospital registration?

You can use a medical insurance card in this case.

Generally speaking, social security cards should be activated at the time of first registration. According to the requirements of designated hospitals, if there is already a hospital card, patients only need to take the social security card and the medical card to a special card to run the "card association" business, so they can use the social security card.

If you don't have a hospital card, make a card first, and then do the "card association" business. However, when seeing a doctor, the patient needs to go to the hospital with the certificate of a new social security card and pay all the expenses. After the social security card is issued, they will go to the medical insurance center for reimbursement.
