National Health Insurance Medical expenses in the event of a traffic accident (third-party action)

In the event of a traffic accident, etc.

As a general rule, the assailant should bear the medical expenses for injuries caused by the actions of others, such as traffic accidents and injuries, according to the percentage of fault.
However, in some cases, such as when the compensation is delayed, you may be able to receive treatment at the National Health Insurance by notifying us. If you receive medical treatment at NHI, NHI will temporarily pay for the medical expenses, excluding the portion borne by the hospital, and later, NHI will bill the perpetrator on behalf of the victim.

When receiving treatment at National Health Insurance, be sure to contact Ward Office 2nd Floor No. 1 (National Health Insurance Benefit Section) in advance and submit the “Notification of Injury or Sickness Caused by the Act of a Third Party,” which will be sent to you.
