According to domestic authoritative media reports, the four departments jointly issued a document to check medical insurance within two and a half years. The reason for checking medical insurance is that nucleic acid detection in some areas has become an interest chain, and there are some problems in local medical insurance.

The interest chain of nucleic acid detection is based on the expenditure of medical insurance. From the very beginning, the purpose of nucleic acid testing is to ensure the elimination of the epidemic as soon as possible, and later nucleic acid testing has become a complete interest industry chain. Although universal nucleic acid testing is free in most areas, nucleic acid testing institutions are not free, and one party still needs to pay the agency fees for nucleic acid testing, and who pays the bill? This is also the reason why it is necessary to strictly check the details of medical insurance for two and a half years, because some areas will take advantage of the medical insurance of ordinary people and the imperfection of medical insurance to withdraw a large amount of cash from medical insurance to pay for nucleic acid testing institutions, thus providing many indicators for local economic development.

In some places, nucleic acid testing has been regarded as an enterprise. For example, some regions began to hold a design competition for nucleic acid detection, and some regions regarded nucleic acid detection as an interest industrial chain to judge the economic development level of each region. Incomplete statistics show that the income and expenditure of nucleic acid detection have accounted for about 3% of the local GDP economic development. This means that in the future, as long as the epidemic still occurs, nucleic acid detection will become more and more important. Even in some areas, nucleic acid testing is the reason to increase local economic income, especially in some small counties. Every resident has to do nucleic acid testing when going out, and the fee is not low. The average cost of a person may be between 28 yuan and 37 yuan.

To sum up, the fundamental reason for checking medical insurance within two and a half years is to strictly investigate the development process of the interest chain of nucleic acid testing and see if nucleic acid testing uses a large amount of cash for illegal operation.
