Legal analysis: Every medical insurance patient will receive a hospitalization medical insurance statement when he leaves the hospital, which records the total hospitalization expenses, out-of-pocket expenses and medical insurance accounting reimbursement expenses. There are two kinds of medical insurance settlement lists, one is the direct settlement of hospitals, and the other is the reimbursement list of social security settlement. This kind of settlement list is often used in commercial insurance medical claims, because some medical insurance claims will have different proportions with and without medical insurance. The list usually lists three items in detail: total expenses, total expenses and out-of-pocket expenses. Commercial insurance reimbursement needs to provide a statement, which is generally the self-funded part of reimbursement.
