Whether crown supplementary medical insurance can be reimbursed depends on the specific situation. Generally speaking, if you buy commercial medical insurance and the insurance contract covers the cost of dental treatment, then the crown can be reimbursed. However, it should be noted that different insurance products may have different restrictions on reimbursement ratio, reimbursement scope and reimbursement conditions. Read the terms of the insurance contract carefully, consult the insurance company or agent to understand the specific reimbursement policy.

In addition, if the crown treatment is carried out in a public hospital and materials and equipment within the scope of medical insurance are used, then medical insurance can also be used for reimbursement. However, it should be noted that the scope and proportion of medical insurance reimbursement may be different due to different regions and policies, and it is necessary to understand the specific local policies.

To sum up:

Whether crown supplementary medical insurance can be reimbursed depends on the specific situation. Those who purchase commercial medical insurance and the insurance contract covers the cost of dental treatment, or those who use materials and equipment in medical insurance coverage for dental crown treatment in public hospitals can be reimbursed. However, it should be noted that different insurance products and medical insurance policies may be different. It is necessary to read the terms of the insurance contract carefully and consult relevant institutions to understand the specific reimbursement policies.
