Transferring a referral to another hospital means that when an insured person visits a designated medical institution, the designated medical institution transfers him or her to a higher level of medical institution due to the condition of medical instruments and equipment, technology or treatment means. Referral is the transfer of a patient from one hospital to another.
It is also a system whereby medical preventive organizations transfer patients treated in their own units to another medical preventive organization for treatment or treatment according to the needs of the condition.
