In the medical insurance reimbursement, the overall fund payment refers to the maximum amount that the insured can get reimbursement from the medical insurance fund within one year. The calculation formula of the overall fund payment is that the overall fund payment is equal to (expenses within the scope of the policy-deductible line) multiplied by the reimbursement ratio. Specifically, the expenses incurred by the insured within the scope of the medical insurance policy, after deducting the deductible, are paid by the overall fund according to the reimbursement ratio.
