Hold the minor insurance card over a card reader with a face recognition machine installed at a medical institution that can be used as a Medical Certificate.
Please select "Use" on the screen of "Do you use various recipient IDs of medical expenses grant?" (Details display vary depending on the system of medical institutions, etc.)

Medical institutions that have already responded to the system (available) that the city currently knows are as follows.
Medical institutions that can respond (as of February 28, 2025) (PDF: 315KB)
Such posters are posted in facilities such as medical institutions that can respond.

With the introduction of the system, medical institutions, etc. will reflect patient information on the receipt computer (hereinafter referred to as "receikon") without entering the public expenditure recipient number, reducing the hassle of input.
In order to introduce the system, it is necessary to repair the Rececon of medical institutions.
The government subsidized the cost of system renovation, but the reception in 2024 ended on February 1, 2025 (homepage of reference country (outside site)).
In the FY2024 supplementary budget of the Ministry of Health, Labour and Welfare, a budget with the same content in mind was included. We will inform you as soon as the details are decided.

As one of the government's efforts to promote healthcare DX, the Digital Agency launched PMH (Public Medical Hub) initiatives in FY2023.
This service is intended to share information on recipients of the medical expenses grant with local governments, medical institutions, etc.
When a municipality registers Medical Certificate information with PMH, it is possible to link the minor insurance card with Medical Certificate.
Based on these national initiatives, Yokohama City was selected as a leading local government in fiscal 2024 for the Subsidies for Medical Expenses for Pediatric Treatment system, the medical expenses subsidy program for single-parent families and the medical expenses subsidy program for severely disabled peopleMedical Certificate.
As a result, from April 10, 2025, if you receive a medical examination at a medical institution in the prefecture that supports PMH, you will be able to receive a medical examination only with a minor insurance card.

By using PMH, it is possible to use My Number Card as Medical Certificate. This eliminates the need for patients to bring paper Medical Certificate to medical institutions in addition to their health insurance card.
In addition, medical institutions can reduce the administrative burden of inputting Medical Certificate information and checking the latest qualification information.

The government is promoting the switch to a minor insurance card to promote medical DX, and plans to integrate with Medical Certificate and patient's card Shinryo-ken nationwide from fiscal 2026 onward.
※For details, please see the website (outside site) of the Digital Agency.
In addition to the Medical Certificate for infant, Welfare Medical Certificate, and Medical Certificate for severely disabled people, we plan to integrate information such as the national medical expenses subsidy program (rehabilitation medical care, nursing care, etc.) with minor insurance cards for fiscal 2026 and beyond.
