Can I borrow someone else's medical insurance card?

Legal analysis: impossible. Because the medical insurance card (social security card) can only be used by myself when seeking medical treatment, and cannot be lent to others. If the insured gives his medical insurance card to others for use, once he exceeds the annual maximum payment limit, he will not be able to enjoy medical insurance reimbursement when he falls ill again.

Legal basis: According to Article 17 of the Regulations on the Supervision and Administration of the Use of Medical Insurance Funds, the insured person should take his medical insurance certificate and present it voluntarily for inspection when seeking medical treatment or purchasing medicines. Insured persons have the right to require designated medical institutions to truthfully issue expense documents and related materials. Insured personnel should properly keep the medical insurance certificate to prevent others from using it. If it is necessary to entrust others to purchase drugs for special reasons, the identity certificates of the principal and the trustee shall be provided. Insured persons shall enjoy medical security benefits according to regulations and shall not enjoy them repeatedly. Insured persons have the right to request medical insurance agencies to provide medical insurance consulting services and put forward suggestions for improvement in the use of medical insurance funds.
