I will be 70 years old this month. Will my copayment be reduced when I go to a medical institution?

From the month following the month of your 70th birthday (if the 1st is your birthday, the month of your birth), the percentage of the co-payment you pay at the medical institution window will be 20% or 30% depending on your income and date of birth from the previous year. It will be one of the percentages.
For those who turn 70, we will issue an "Elderly Beneficiary Certificate" stating the co-payment ratio. From the following month, please present your insurance card and your elderly beneficiary certificate at the reception desk of the medical institution.
In addition, households exempt from resident tax can apply for a “Certificate of Application of Maximum Amount/Standard Copayment Reduction” and present it at the counter of a medical institution. up to the maximum amount. In addition, if there is unpaid insurance tax, the "Certificate of Maximum Amount Application/Standard Contribution Reduction Certificate" may not be issued.

Note: Even if you are eligible for the 30% copayment, if the total income of National Health Insurance subscribers aged 70 or over is less than 5.2 million yen for two or more people, or less than 3.83 million yen for one person, you can apply. This will result in a 20% charge.
