Now there are domestic drugs have fallen into 1500 yuan / month, and now can also be medical reimbursement, which is about 400-500 yuan / month. The third generation targeted drug Ocitinib, which first required 50,000 yuan/month, has now dropped to about 15,000 yuan/month, which is also reimbursable. Although most of the targeted drugs are now covered by medical insurance, there will be some differences by region.
