In China, the date of issuance of the notice of payment of medical insurance expenses of the unit may be different according to the regulations of the regional and local social insurance management departments and the arrangement of the payment system. Under normal circumstances, social insurance premiums are collected once a month, and the specific notice may be issued at the beginning of the month or in the middle of the month, but there is no national unified date.

In order to obtain accurate information, it is recommended that you directly consult the human resources department of your unit or the local social insurance administration. They can provide the latest collection schedule and related process information. In addition, if the unit has an online social insurance management system, it can issue payment notices through the system, and the financial or human resources management personnel of the unit should be able to access these notices.

I hope the above content can help you. Please consult a professional lawyer if you have any other questions.
