About medical expenses notice

Once a year, the Yokohama National Health Insurance sends a “medical expenses Notice” to the head of the household, indicating the total amount of medical expenses for all households who have visited medical institutions.
The medical expenses Notification is sent to help you deepen your awareness of the medical expenses burden structure of the National Health Insurance and your health (it will not be sent unless there is a patient in your household).
For more information, please contact each ward office Insurance and Pension Division National Health Insurance Section (bottom page).

The medical expenses notification from January to December 2024 will be sent out on February 12, 2025. It will be delivered to you two days after the shipment to one week later.
This medical expenses notice is available for filing a medical expenses deduction. However, some consultations may not be described in the notice, or the names of medical institutions may not be listed. In that case, it will be necessary to supplement the medical expenses notice and prepare a separate statement of “medical expenses Deduction” and keep the receipt after the declaration.
You may also need to correct the amount of medical expenses paid.
In accordance with the enforcement of a law that partially amends the employee health insurance Law, etc. on October 1, 2020, it was prohibited to request the insured person identification number for purposes other than the execution of the employee health insurance business or related affairs.
Therefore, when sending a medical expenses notice to the tax office for medical expenses deduction, please mask your insured card number by yourself.

For details on the medical expenses deduction, please check the NTA website (external site) or contact the tax office in charge of your area.
