Chapter XI Miscellaneous Provisions (Articles 110 to 113-3)
The law as Act Partially Amending the Health Insurance Act, etc. (Act No. 31 of 2026) leaves it, with the words it changes marked.
The main text is read a page at a time: a chapter to a page, and a long chapter in runs of articles. The whole main text, and the supplementary provisions and appended tables this amendment changes. Those it leaves untouched are on the page for the text in force.
The right to collect insurance premiums and other monies to be collected pursuant to the provisions of this Act or to receive refunds of such monies and the right to receive insurance benefits shall be extinguished by prescription after a lapse of two years from the time when these rights may be exercised.
保険料その他この法律の規定による徴収金を徴収し、又はその還付を受ける権利及び保険給付を受ける権利は、これらを行使することができる時から二年を経過したときは、時効によつて消滅する。
Any notice of collection of, or any demand for, insurance premiums or any other money to be collected pursuant to the provisions of this Act shall have the effect of renewal of prescription.
保険料その他この法律の規定による徴収金の徴収の告知又は督促は、時効の更新の効力を生ずる。

保険料の賦課決定は、当該年度における最初の保険料の納期（この法律又はこれに基づく条例の規定により保険料を納付し、又は納入すべき期限をいい、当該納期後に保険料を課することができることとなつた場合にあつては、当該保険料を課することができることとなつた日とする。次項において同じ。）の翌日から起算して二年を経過した日以後においては、することができない。
A determination of assessment that reduces the amount of insurance premiums in the case where, after a determination of assessment of insurance premiums has been made, it becomes evident, due to grounds not attributable to the insured person, that adjustment is required in the relationship of application with the respective Acts on medical insurance concerning insured persons (meaning the Health Insurance Act, the Mariners Insurance Act, the National Public Officers Mutual Aid Association Act, the Local Public Officers, etc. Mutual Aid Association Act or the Private School Personnel Mutual Aid Association Act) may, notwithstanding the preceding paragraph, be made even on or after the day on which two years have elapsed from the day following the due date for payment of the first insurance premium for the fiscal year, until the day on which a period equivalent to the period found necessary for the adjustment has elapsed from the day following the due date for payment of the first insurance premium for that fiscal year.
保険料の賦課決定をした後に、被保険者の責めに帰することのできない事由によつて被保険者に関する医療保険各法（健康保険法、船員保険法、国家公務員共済組合法、地方公務員等共済組合法又は私立学校教職員共済法をいう。）との間における適用関係の調整を要することが判明した場合における保険料の額を減少させる賦課決定は、前項の規定にかかわらず、当該年度における最初の保険料の納期の翌日から起算して二年を経過した日以後であつても、当該年度における最初の保険料の納期の翌日から起算して調整に必要と認められる期間に相当する期間を経過する日まですることができる。
The provisions of the Civil Code (Act No. 89 of 1896) concerning periods apply mutatis mutandis to the calculation of periods prescribed in this Act or orders based on this Act.
この法律又はこの法律に基づく命令に規定する期間の計算については、民法（明治二十九年法律第八十九号）の期間に関する規定を準用する。
