Supplementary Provisions, Article 5Adjustment in Case of Change in Premium Rate for Each Prefecture
第五条（都道府県単位保険料率の変更の場合における調整）
In the case where a premium rate for each prefecture is changed, the criterion specified by Cabinet Order as referred to in Article 31 of the Supplementary Provisions of the 2006 Health Insurance Act, etc. Amendment Act for the calculation of that premium rate for each prefecture is the difference between the rate obtained by adding, to the average premium rate in the business year to which the transitional month of application belongs (where the transitional month of application is March, the business year following the business year to which that March belongs; the same applies hereinafter in this paragraph and paragraph (1) of the following Article), the transitional base rate for fiscal 2010 and thereafter, which the Minister of Health, Labour and Welfare specifies, taking into account the distribution of the premium rates for each prefecture before adjustment under the provisions of the following Article in the business year to which that transitional month of application belongs and the period from that transitional month of application through March 2020, within the range of the difference between the fiscal 2009 transitional base rate and the rate obtained by deducting the average premium rate in the business year to which that transitional month of application belongs from the highest premium rate for each prefecture in the business year to which that transitional month of application belongs, and 82/1,000.
都道府県単位保険料率の変更の場合における当該都道府県単位保険料率の算定についての平成十八年健保法等改正法附則第三十一条の政令で定める基準は、経過措置期間適用月の属する事業年度（経過措置期間適用月が三月の場合にあっては、当該三月の属する事業年度の翌事業年度。以下この項及び次条第一項において同じ。）における平均保険料率に、当該経過措置期間適用月の属する事業年度における次条の規定による調整前の都道府県単位保険料率の分布状況及び当該経過措置期間適用月から平成三十二年三月までの期間を勘案して、平成二十一年度経過措置基準率と当該経過措置期間適用月の属する事業年度における最高都道府県単位保険料率から当該経過措置期間適用月の属する事業年度における平均保険料率を控除した率との差の範囲内において、厚生労働大臣が定める平成二十二年度以降経過措置基準率を加えた率と千分の八十二との率の差とする。
The transitional base rate for fiscal 2010 and thereafter referred to in the preceding paragraph is to be set, as the rate to be applied for each business year from fiscal 2010 through fiscal 2019, by the end of the business year preceding each such business year, as a rate that is equal to or more than the transitional base rate for fiscal 2010 and thereafter referred to in that paragraph that was set as that to be applied in the business year preceding each such business year; provided, however, that the transitional base rate for fiscal 2010 and thereafter referred to in that paragraph that is to be applied in fiscal 2010 is a rate that is equal to or more than the fiscal 2009 transitional base rate.
前項の平成二十二年度以降経過措置基準率は、平成二十二年度から平成三十一年度までの各事業年度ごとに適用されるべき率として、それぞれ当該各事業年度の前事業年度末までに、当該各事業年度の前事業年度に適用されるべきものとして定めた同項の平成二十二年度以降経過措置基準率以上の率として定めるものとする。ただし、平成二十二年度に適用されるべき同項の平成二十二年度以降経過措置基準率は、平成二十一年度経過措置基準率以上の率とする。
