The<unk>  is the eleventh revision of the International Classification of Diseases, and will replace the<unk>  as the global standard for coding health information and causes of death. The<unk>  is developed and annually updated by the World Health Organization (WHO). Development of the<unk>  started in 2007 and spanned over a decade of work, involving over 300 specialists from 55 countries divided into 30 work groups, with an additional 10,000 proposals from people all over the world. Following an alpha version in May 2011 and a beta draft in May 2012, a stable version of the<unk>  was released on 18 June 2018, and officially endorsed by all WHO members during the 72nd World Health Assembly on 25 May 2019. The<unk>  is a large taxonomy consisting of about 85,000 entities, also called classes or nodes. An entity can be anything that is relevant to health care. It usually represents a disease or a pathogen, but it can also be an isolated symptom or (developmental) anomaly of the body. There are also classes for reasons for contact with health services, social circumstances of the patient, and external causes of injury or death. The<unk>  is part of the WHO-FIC, a family of medical classifications. The WHO-FIC contains the Foundation Component, which comprises all entities of all classifications endorsed by the WHO. The Foundation is the common core from which all classifications are derived. For example, the<unk> -O is a derivative classification optimized for use in oncology. The primary derivative of the Foundation is called the<unk>  MMS, and it is this system that is commonly referred to as simply "the<unk> ". MMS stands for Mortality and Morbidity Statistics. Both the Foundation Component and the<unk>  MMS can be viewed online on the WHO's website. The<unk>  is distributed under a Creative Commons BY-ND license. The<unk>  officially came into effect on 1 January 2022. However, the WHO acknowledged in 2018 that "not many countries are likely to adapt that quickly". Currently, no country has officially switched to the<unk>  yet. In the United States, a group that advises the Secretary of Health and Human Services has given an expected implementation year of 2025, but if a clinical modification is determined to be needed (similar to the<unk> -CM),<unk>  implementation might not begin until 2027. An online proposal platform (self-registration required) allows users to submit evidence-based suggestions for the improvement of the<unk> .
