Why can't medical insurance be used when social security is paid normally?

Legal analysis: 1, late payment fee, social security (medical insurance) card suspends medical insurance function. Insured persons who pay social medical insurance premiums for employees on a monthly basis (including on-the-job employees, flexible employees and deferred retirees). Social medical insurance premiums payable to employees must be paid in the current month, and they can enjoy medical insurance benefits in the next month. If the payment of social insurance premiums is stopped in the current month, the medical insurance bookkeeping function will be stopped or suspended from the following month 1.

2. The hospital system is out of order. Sometimes there is a system failure when the hospital settles, so it can only be settled at its own expense first.

3. The system information is wrong. In rare cases, the information of the insured in the medical insurance system will be wrong in the transmission process. If you are sure that there are no other objective reasons (such as system failure in the hospital), you can bring your ID card and social security (medical insurance) card to the service front desk of each secondary medical insurance agency, and the staff will adjust the system error information for you as soon as possible to ensure your normal medical insurance treatment.

Legal basis: Article 4 of the Notice of Ministry of Human Resources and Social Security on Printing and Distributing Social Security Cards is constructed according to the principle of "one card is multi-purpose and universal". The issuance of social security cards in all localities must comply with the requirements of safety, integrity and public welfare, adopt unified national standards and norms, and ensure their use throughout the country.
