National health insurance and traffic accident

In the case of injury in a traffic accident, in principle, the perpetrator pays the treatment cost. Although you can receive treatment at the National Health Insurance Association, you will be billed from the National Health Inspector to the perpetrator at a later date, so please be sure to notify me if you use National Health Insurance.

Things to bring

  • マイナ保険証または国保の資格確認書
  • Inkan seal
  • Traffic accident certificate

Expensive medical expenses

 限度額適用認定証を提示した場合は、窓口での支払いが下記の限度額までとなります。限度額認定証の申請は、役場の保健福祉課保険医療係でできますので、マイナ保険証または資格確認書と印鑑を持ってお越しください。
 なお、限度額認定証の申請ができない場合は一度窓口で自己負担をして、国保に申請して認められれば後日、高額医療費として支給されます。
