Medical insurance designated hospitals generally refer to all hospitals designated by the Social Security Bureau to participate in medical reimbursement.

However, patients with social security cards cannot be reimbursed at every designated hospital at any time. For example, if you want to see a doctor in Chang 'an Hospital and reimburse medical insurance expenses, then you must first issue a "referral form" at your health service station, and Chang 'an Hospital will recognize it. Moreover, the "referral form" is valid for 3 days, and a "referral form" needs to be reissued after 3 days.
