Health insurance cards (health insurance eligibility information)

You can use your health insurance card after you join the Health Insurance Association and your eligibility information is registered. Note that health insurance cards are no longer newly issued or reissued since December 2, 2024. Use a Myna health insurance card.

POINT
  • Do not forget to present your Myna health insurance card at the reception counter when visiting a hospital to receive medical care.
  • Promptly notify the Health Insurance Association of any changes in your health insurance eligibility information.

Using your Myna health insurance card when seeing a doctor gives you access to the required medical care by paying only the amount of your copayment.

Caution:

Use of current health insurance cards was abolished on December 2, 2024 and they are no longer newly issued or reissued since then.
(Health insurance cards already issued will remain valid for up to one year after this date as a provisional measure.)
Use a Myna health insurance card to get examinations and treatment at medical care institutions and other facilities.

  • * Myna (My Number) health insurance card: This is an Individual Number Card (also called "My Number Card") registered for use as a health insurance card. (You must be issued an Individual Number Card and complete registration for use on Mynaportal or elsewhere.)
  • * Those who do not have a Myna health insurance card can use an Eligibility Verification Certificate issued by the Health Insurance Association to get examinations and treatment at medical care institutions and other facilities.

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 Association 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 (up to five years, depending on the Health Insurance Association). Additionally, it must be returned to the Health Insurance Association 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, in cases such as when visiting a medical care institution that is not required to adopt the online eligibility verification system.

To enable smooth verification of eligibility using a Myna health insurance card to get medical care

To avoid cases of visiting a medical care institution or other facility and presenting a Myna health insurance card before data has been registered by the Health Insurance Association, please note the following points when applying for eligibility as an insured person or dependent.

  • You can use your Individual Number Card to get medical care only after the Health Insurance Association receives a notification of eligibility (or, for dependents, a notification of dependents; “Notification of Eligibility, etc.” hereinafter) that indicates the correct Individual Number, name, date of birth, gender, and address (“Individual Number, etc.” hereinafter) and the Society completes data registration. (You cannot use your Individual Number Card to get medical care until data registration is complete.)
  • If the Notification of Eligibility, etc. indicates the correct Individual Number, etc., data registration will typically be completed within five days after the Notification of Eligibility, etc. is submitted to the Health Insurance Association.
  • Check the following points in cases in which the correct Individual Number is not shown on a document submitted by the member in relation to certification of eligibility.
    • The Notification of Eligibility, etc. is required by law to indicate the Individual Number and the Individual Number is necessary for data registration.
    • It may take some time for data registration to be completed.
    • You cannot use your Individual Number Card as a Myna health insurance card until data registration is complete.
    Employers are asked to submit Individual Numbers promptly to speed the data registration process. Note the following:
    • The Notification of Eligibility, etc. is required by law to indicate the Individual Number.
    • If the employer fails to promptly submit the Individual Number, the Health Insurance Association will need the number of days specified by the Health Insurance Association to complete the data registration (the standard processing period in cases other than when the Individual Number cannot be obtained from J-LIS).
    • You cannot use your Myna health insurance card until data registration is complete.
  • Before using your Individual Number Card to get medical care for the first time after a change in your eligibility status, access Mynaportal and check to confirm that your health insurance card information reflects the change in eligibility.

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 were issued "elderly benefits cards" showing their copayment percentages. However, from December 2, 2024, elderly benefits cards will in principle be issued to those who have an Eligibility Verification Certificate. (Up until December 1, 2025, they can be issued to those who have a valid health insurance card.)

Note that an elderly benefits card is not required when using a Myna health insurance card. Use your Myna health insurance card alone.

Online verification of eligibility

Online verification of eligibility has been introduced, making it possible to verify eligibility information online using the Individual Number Card, etc. 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. (Requires advance registration on Mynaportal etc.)
See here for more information.

If online verification of eligibility fails using the Individual Number Card

If online verification of eligibility fails using the Individual Number Card for any reason (e.g., indication of "Eligibility (invalid)" or "No eligibility information" or defective device), eligibility can be verified by the following methods:

  • Presenting your health insurance card (until December 1, 2025)
  • Presenting the eligibility information screen of Mynaportal (including downloaded image file) on a smartphone or other device
  • Verbal confirmation that there has been no change in the eligibility status from your medical history (if all information that should be shown on the Notification of Eligibility as Insured Person can be checked)
  • Submitting a Notification of Eligibility as Insured Person

With the introduction of online verification of eligibility, a branch number has been added

With the introduction of online verification of eligibility, a two-digit branch number has been added to the code and number of each insured person or dependent to allow individual identification.
The branch number that appears on an elderly benefits card is the branch number for the insured person (00). Thus, the health insurance card and the elderly benefits card for a dependent will have different branch numbers. If you are asked by a medical care institution to verify your branch number, tell the institution that the branch number shown on the health insurance card is your own branch number.
