How to bind the second social security to the hospital

Social security is divided into outpatient service and hospitalization. Secondary outpatient service needs to be bound with social security, while hospitalization does not need to be bound with hospital. Third-level outpatient service and hospitalization need to be bound to social health or hospital. The second kind of hospitalization pays for itself. If you need to be hospitalized, you don't need to open a referral form. If it's an outpatient clinic, you can't open a referral form.

If you don't open it, you can be hospitalized, but the reimbursement will be reduced.
