マイナンバーカードの健康保険証利用の本格運用がスタートしました｜デジタル庁

This page announces the full implementation of health insurance certificate functions using My Number Cards starting October 20, 2021. Registration is required via My Number Portal, Seven Bank ATMs, or card readers at medical facilities. Key benefits include sharing medical information at first visits, exemption from high medical expense limits without pre-approval documents, smooth insurance verification using facial recognition, and improved administrative efficiency. The card remains usable across job changes and relocations, promoting sustainable healthcare system operations.
