In the event of an extremely anomalous and severe disaster, for which temporary medical facilities related to the relevant disaster (which means temporary facilities for conducting medical care for disaster victims; hereinafter the same applies in this Article) are remarkably insufficient and it is found particularly necessary to provide disaster victims with medical care speedily, that disaster is to be designated by Cabinet Order.
著しく異常かつ激甚な非常災害であつて、当該災害に係る臨時の医療施設（被災者に対する医療の提供を行うための臨時の施設をいう。以下この条において同じ。）が著しく不足し、被災者に対して医療を迅速に提供することが特に必要と認められるものが発生した場合には、当該災害を政令で指定するものとする。
When designation under the preceding paragraph is made, the provisions of Chapter IV of the Medical Care Act (Act No. 205 of 1948) do not apply to the temporary medical facilities which the head of the local government establishes in the areas and during the period provided for by Cabinet Order.
前項の規定による指定があつたときは、政令で定める区域及び期間において地方公共団体の長が開設する臨時の医療施設については、医療法（昭和二十三年法律第二百五号）第四章の規定は、適用しない。
If designation under paragraph (1) is made, the provisions of paragraphs (2) and (3) of the preceding Article apply mutatis mutandis to temporary medical facilities prescribed in the preceding paragraph.
