Myna Insurance Cards

A Myna health insurance card is an Individual Number Card registered for use as a health insurance card. By using your Myna health insurance card at an insurance medical care institution, you can receive treatment by paying only your copayment, without having to pay the entire medical care costs.
To use a Myna health insurance card, you must register in advance on Mynaportal or elsewhere. We encourage you to obtain an Individual Number Card if you do not have one.

If your Individual Number Card is lost or stolen

If your Individual Number Card is lost or stolen, call the Individual Number comprehensive toll-free number to take the procedures to terminate the functionality of your Individual Number Card.
Also file a lost/stolen property report with the police and note down the reception number. Then, complete the procedures at the municipal office of your area to have your Individual Number Card reissued.

Individual Number Card expiration dates

Note the expiration date of your Individual Number Card and that of the electronic certificate uploaded on the Individual Number Card (used when using your Individual Number Card as a health insurance card).
Your Individual Number Card will expire on the tenth birthday after the date the card was issued. The electronic certificate will expire on the fifth birthday after the date of issue.

• * An expiration notice will be sent to the person in question two or three months before the expiration date. Renewal is free of charge.

Eligibility verification certificate, notice of eligibility information

Even if your eligibility cannot be verified using a Myna health insurance card, you can still get medical care covered by health insurance using either of the following forms:

Eligibility verification certificate

Those who do not have an Individual Number Card or who have not registered their Individual Number Card for use as a health insurance card can use this form to get medical care at medical care institutions and other facilities.
From December 2, 2024, Eligibility Verification Certificates will be issued upon application, but the Health Insurance Society will issue by its authority the certificates to those who cannot use a Myna health insurance card. However, if you have a valid health insurance card during the transitional period until December 1, 2025, you may not be issued an Eligibility Verification Certificate even if you apply.
An Eligibility Verification Certificate has an expiration date (in the Health Insurance Association’s case, the expiration date is the end of the year of joining the Association; e.g., if you joined in January 2025, the Eligibility Verification Certificate will be valid through the end of December 2025). Additionally, it must be returned to the Health Insurance Society if the bearer loses eligibility before the expiration date.

Notice of eligibility information

This form, which makes it easy to check member codes/numbers and other information, is sent to all members in principle. (Sent to new members from December 2, 2024.)
Note that you cannot get medical care covered by health insurance using just a notice of eligibility information. You can get medical care covered by health insurance by presenting this form together with your Myna health insurance card.

Elderly benefits cards

Since the percentage of medical care costs paid by elderly persons aged 70-74 to medical care institutions varies with income, these persons had been issued an elderly benefits card showing each person’s copayment percentage. However, since December 2, 2024, elderly benefits cards are issued in principle to those who have an Eligibility Verification Certificate (also issued to those who have a valid health insurance card until December 1, 2025).
If you have a Myna health insurance card, you don't need to show an elderly benefits card.

Online verification of eligibility

Online verification of eligibility has been introduced, making it possible to verify eligibility information online using the IC chip on the Individual Number Card. You can use your Individual Number Card as a health insurance card at medical care institutions and other facilities that have adopted the online eligibility verification system.

If you cannot complete online verification of eligibility using your Individual Number Card

If you cannot complete the online verification of eligibility using your Individual Number Card for any reason (e.g., for errors involving invalid eligibility, absence of eligibility information, or equipment problems), you can verify your eligibility by one of the following methods:

• Presenting your health insurance card (until December 1, 2025)
• Presenting the eligibility information screen on Mynaportal (including a downloaded screen) on a smartphone or other device
• Oral verification that your eligibility information has not changed from past examination records (if you are able to ascertain the information that should be included on the application for eligibility as an insured person)
• Presenting your Notice of Eligibility Information
