There are many types of targeted drugs for lung cancer, and the prices vary greatly, among which, ERSA is a relatively low-priced targeted drug and the most widely used at present. Since drug prices and health insurance policies vary from region to region, here is an example of the price in Zhejiang Province only. The price of a single box of ERSA is about 2,300 yuan, and a one-month course of treatment costs about 7,000 yuan. For urban workers’ medical insurance, because of the better policy, it can be reimbursed 90%, and you need to bear 700 RMB per month. In Hangzhou, the reimbursement rate of employees’ medical insurance can reach 97%, and the individual only needs to bear 200 RMB per month. The urban residents’ medical insurance reimbursement rate is 75%-85%, and the individual has to bear about 1,500 RMB. The rural medical insurance reimbursement ratio is lower, only about 60%, and the individual needs to bear about 2500-3000 RMB, which is the approximate price of Erythroxa.
