By analyzing the basic medical insurance fund expenditure and change of the number of visits in designated hospitals in Beijing Economic-Technological Development Area before and after the epidemic, and comparing the changes in the regularity of patients' visits in other areas and different levels of hospitals in Beijing, we discussed how to allocate, manage and use medical insurance funds more accurately for medical institutions of different levels under normalization of the epidemic. The results show that in the early stage of the epidemic, patients will reduce the number of medical visits, the grass-roots diversion is more obvious, and the fund declaration amount and the number of medical visits have dropped significantly. Hospitals in the six disctricts of cities dropped more than suburban hospitals. In the late stage of the epidemic, various indicators rebounded integrally and some patients still chose to seek medical treatment in the suburbs. The construction of suburban medical institutions, community medical institutions and medical insurance policy support should be further increased, the people should be encouraged to diagnose and treat at different levels, and a more rational medical resource pattern should be established.
