Overall medical insurance payment refers to paying the insured's medical expenses from the overall medical insurance fund. The medical insurance pooling fund consists of the medical insurance expenses paid by the insured and the part paid by the unit, in which the residents' medical insurance expenses directly enter the medical insurance pooling fund account, and the employees' medical insurance units also enter the medical insurance pooling fund account. The money spent on the overall medical insurance payment comes from the social security fund and is paid by the insured and the unit. This arrangement is to ensure that the insured can get timely reimbursement and compensation when they need medical services.
