ICD-11
The ICD-11 is the eleventh revision of the International Classification of Diseases, due to replace the ICD-10 as the global standard for coding information about diseases and causes of death. The ICD-11 is developed and regularly updated by the World Health Organization (WHO). Its development 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 ICD-11 was released on 18 June 2018, and officially endorsed by all WHO members during the 72nd World Health Assembly on 25 May 2019.

The ICD-11 is a large taxonomy consisting of tens of thousands of 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 collection of all ICD-11 entities is called the Foundation Component. From this common core, various subsets can be derived; for example, the ICD-O is a derivative classification optimized for use in oncology. The primary derivative of the Foundation is called the ICD-11 MMS, and it is this system that is commonly referred to as simply "the ICD-11". MMS stands for Mortality and Morbidity Statistics. Both the Foundation Component and the ICD-11 MMS can be viewed online on the WHO's website.

The ICD-11 will officially come into effect on 1 January 2022, at which time member nations may begin reporting morbidity and mortality statistics using the ICD-11 nosology. Each country chooses when to adopt ICD-11, and WHO has acknowledged that "not many countries are likely to adapt that quickly", i.e. begin using the ICD-11 by the time of its launch. 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 ICD-10-CM), ICD-11 implementation might not begin until 2027.
