マイナンバーカードの健康保険証利用登録・利用登録解除

Starting December 2, 2024, issuance of the current health insurance cards will cease and we will move to a system based on using My Number cards as health insurance cards.
Note: Using your My Number card can only be done at medical institutions and pharmacies that have a card reader installed.
Note: You can still receive medical treatment with your health insurance card as usual.
Note: Initial registration is required to use your health insurance card.

You can view your specific health checkup information and drug information on Mynaportal.
In addition, if you give your consent, medical institutions, etc. will be able to view specific health checkup information and information on drugs you have taken.
The quality of medical care can be improved by being able to diagnose and prescribe according to your own information.

If you have registered your health insurance card on your My Number card and use a medical institution that can verify your medical insurance eligibility online, you will not need to present a "Limit Applicable Certificate" or similar document.

You can also check your medical expenses notification information on My Number Portal. In principle, information for the previous month's medical treatment is updated on the 11th of each month.
However, some information is not displayed, such as the treatment costs for judo therapy, acupuncture and moxibustion, and massage.

Please refer to the following website of the Ministry of Health, Labor and Welfare for the latest information on medical institutions and pharmacies where My Number Card can be used as a health insurance card.

Please note that in order to use your My Number Card as a health insurance card, you will need to "register for the first time" from Mynaportal.

• Register from a smartphone that can read My Number Card
• Register from a computer (card reader required)
• Register from a Seven Bank ATM
• Register from the Mynaportal terminal at the city hall (Please bring your My Number card and come to the Insurance and Pension Division.)

If you wish to cancel the registration of your My Number card as a health insurance card, you will need to apply for cancellation to your medical insurer.
How to apply if you are enrolled in National Health Insurance

Please fill out the application form above and submit it to the City Hall Insurance and Pension Division or Hirao/Wakabadai Branch Office.
Note: If you cancel your registration, you will no longer be able to perform online eligibility verification using your My Number card.
Note: After the lifting of the restrictions, you will need to bring your insured card or eligibility certificate when visiting a medical institution or pharmacy.
Note: If you do not have a valid insurance certificate or eligibility confirmation certificate at the time of applying for cancellation, you will be issued an insurance certificate or eligibility confirmation certificate.
Note: After you cancel your registration, it will take approximately one to two months for the change to be reflected on the "Health Insurance Card Registration Application Status" screen on My Number Portal.
