The 43rd World Health Assembly in 1990 approved the Tenth Revision of the International Classification of Diseases (WHA 43,24) and endorsed the recommendation of the International Conference for the Tenth Revision of the ICD.

4 Held in Geneva from 26 September to 2 October 1989 concerning the establishment of an updating process within the 10-year revision cycle. This recommendation was put into motion at the annual meeting of WHO Collaborating Centres for the Family of International Classifications in Tokyo, Japan in 1996 and later a formal mechanism to guide the updating process was established. According to this updating mechanism minor updates are made each year while major updates are made, if required, every three years. For more information regarding the updating process and a cumulative list of the updates please see http://www. Future updates will also be posted on this site. The 2010 Edition of ICD-10 can also be referred to as the 4th Edition of ICD-10 .
