At present, the urban workers' medical insurance system is becoming more and more perfect, and the new type of cooperative medical care is also showing initial success. However, urban children and adolescents have become a missing link in the social security system. In most places, the medical insurance for primary and secondary school students and infants is almost zero. The treatment of seriously ill children depends mainly on social donations and some commercial insurance. The lack of institutional guarantees for social fundraising is limited and can only solve the difficulties of a small number of people. . Commercial insurance often excludes children with malignant tumors, various kidney diseases, and blood diseases because of the huge operational risks of major diseases. We can't count how many children were forced to delay or even give up treatment because of high medical expenses, and how many families fell into the abyss of poverty. Children and adolescents are a vulnerable group in society, and at the same time they are the hope of a family and even a country and a nation. Incorporating them into the public care vision and implementing a wide-ranging system of children's medical insurance has become an increasingly urgent call in modern society. With regard to children's medical insurance, there have been some explorations in various places, such as the establishment of a system of mutual help for children's medical care. These attempts have positive significance in filling the gaps in the medical insurance for children in cities, but the common feature of these measures is that the family is responsible for raising funds for protection, ie Parents give each child a certain fee for each academic year. The child can enjoy tens of thousands of medical subsidies per year, or it is a "social mutual aid" nature. Nowadays, we can find many highlights in the Interpretation of the Trial Measures for Medical Insurance for Children and Inpatients in Outpatients. For example, it has certain mandatory, the scope of insurance coverage has been extended to the children of laborers, and the reimbursement standard is the highest. The insurance premiums are financed by the financial and children's families. These all reflect the city's fair, open, inclusive and valuable feelings. The generous sun sprinkles the splendid sprinkles on the towering trees, and also shines out the green shoots, so it is full of lush and alive. Medical insurance is also a piece of life. While illuminating adults, it is also necessary to shine on vulnerable children so that they can grow up healthily and vigorously. The children's medical insurance has already opened a good start. The author hopes that there will be more places to pay attention to children's medical insurance, promote children's medical insurance, and provide powerful protection for more children.
