Medical insurance generally refers to basic medical insurance, which is a social insurance system established to compensate workers for economic losses caused by disease risks. The medical insurance fund is established through the contributions of employers and individuals. After the insured person has medical expenses, the medical insurance institution will give certain economic compensation. The establishment and implementation of the basic medical insurance system has gathered the economic strength of units and social members, enabled the sick social members to obtain the necessary material help from society, reduced the burden of medical expenses, and prevented the sick social members from "poverty due to illness". Medical insurance has the basic characteristics of social insurance, such as compulsion, mutual assistance and sociality. Therefore, the medical insurance system is usually enforced by national legislation and a fund system is established. The expenses are paid jointly by the employer and the individual, and the medical insurance premium is paid by the medical insurance institution to solve the medical risks caused by the illness or injury of the employees.
Subsidized medical insurance is medical insurance in which the insurance company pays the insurance premium to the insured by time, by day or by project according to the subsidy standard stipulated in the contract. Claims have nothing to do with actual medical expenses, and invoices are not needed. It is suggested that the reimbursement of medical expenses should be considered first when purchasing medical insurance, and then the compensation for losses caused by hospitalization can be considered. Only by consolidating the basic guarantee and supplementing it on this basis can we add icing on the cake. People with adequate social insurance can give priority to subsidizing medical insurance when choosing medical insurance. Insurance principle In insurance, there is a question whether the compensation principle is applicable to health insurance. This problem cannot be generalized. The principle of compensation means that "the compensation obtained by the insured cannot be higher than its actual loss". Subsidized medical insurance is not applicable, and the payment of insurance benefits has nothing to do with actual losses. In fact, its design principle is to consider the wage loss caused by sick leave during the hospitalization of the insured, so it is agreed in the contract that the subsidy fee will be paid according to the number of days of hospitalization. Regardless of the actual hospitalization expenses, it has nothing to do with the actual economic losses. It is a kind of "fixed value insurance".
