The core idea of overall medical insurance payment is to pay medical expenses from the medical insurance fund to ensure that the economic burden of the insured in medical services is reasonably shared. Under this payment method, the insured only needs to pay part of the medical expenses, and the rest is borne by the medical insurance fund. This will help to improve the fairness and sustainability of the medical insurance system and ensure that the insured can get the necessary help when they need medical care, without being limited by the cost. The management requirements of the medical insurance pooling fund are strict, ensuring the special use and storage of the fund and preventing misappropriation, so as to ensure the effective operation of the medical insurance system and the safety of the fund.
