Registering and cancelling your My Number card for use as a health insurance card

Updated: October 28, 2024

Using your My Number card as a health insurance card

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 "specific health checkup information" and "drug information" from Mynaportal.

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 the drugs you have taken so far.
The quality of medical care can be improved by being able to diagnose and prescribe according to your own information.

There will be no need to make lump-sum payments above the limit at medical institutions or pharmacies.

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.

Medical expenses notification information can be linked to the data when preparing tax returns

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.
