the part paid by the medical insurance unit will be transferred to the overall fund for reimbursement of the insured. The overall fund is an important part of the medical insurance fund, which is managed by the medical insurance agency to pay the medical expenses incurred by the insured. When the insured person seeks medical treatment, the medical expenses that meet the requirements will be settled by the medical insurance agency and the medical institution, and the part borne by the medical insurance fund will be paid by the overall fund. Specifically, after the part paid by the medical insurance unit enters the overall fund, it will be used to pay the medical expenses such as hospitalization, outpatient service and medicines incurred by the insured. These expenses shall be settled by the medical insurance agency and the medical institution within the prescribed scope, and the part borne by the medical insurance fund shall be paid by the overall fund. This is to protect the basic medical needs of the insured and improve the level of medical security. In addition, the medical insurance personal account is also an important part of the medical insurance fund, which is used to pay for the insured's personal outpatient service, drug purchase and other expenses. The source of funds for individual accounts includes a certain proportion of individual contributions and unit contributions. When the insured uses the personal account, the funds will be deducted from the personal account. If the balance of the personal account is insufficient, the individual will bear the rest. In short, after the medical insurance unit pays part into the overall fund, it will be used to pay the medical expenses of the insured to ensure their basic medical needs. At the same time, the personal account will also be used within the prescribed scope to facilitate the use of the insured.
