What is the blacklist of medical insurance?

There are several possibilities for social security cards to become "blacklists":

First, the balance in the medical insurance payment card is insufficient, resulting in arrears, which makes the medical insurance card unusable. In this case, please ask the insured to issue a notice of arrears to the social security window of Yiwu Administrative Service Center, and then return to the social security window to handle the relevant formalities after paying the money to the local tax department.

Second, the social security payment is in a state of interruption, and the insured needs to pay the interrupted medical insurance fee before it can be reopened.

Third, after the insured person changes the unit, the connection between the two insured units is interrupted, and it still cannot be automatically opened after payment. The insured person needs to go through the relevant opening procedures at the social security window.
