Why can't Changsha Bank's medical insurance card find money at the counter?

The situation varies from place to place.

There is no personal account balance on the medical insurance card, which has a lot to do with the local medical insurance information system. Or it has a lot to do with your query method.

You can bring your social security card or ID card directly to the medical insurance agency in the insured area, or you can call the local social security consultation telephone number 12333.
