===ICD===
The International Classification of Disease ([[ICD]]) is the most widely recognized medical classification. Maintained by the [[World Health Organization]] ([[WHO]]),<ref name="Electronic Health Records: A Practical Guide for Professionals and Organizations.">Margret K. Amatayakul, MBA, RHIA, CHPS, CPHIT, CPEHR&FHIMSS.(2009).Electronic Health Records: A Practical Guide for Professionals and Organizations.Chicago, America:AHIMA</ref> its primary purpose is to categorise diseases for morbidity and mortality reporting. However the coded data is often used for other purposes too; including reimbursement practices such as [[medical billing]]. ICD has a hierarchical structure, and coding in this context, is the term applied when representations are assigned to the words they represent.<ref name="Electronic Health Records: A Practical Guide for Professionals and Organizations."/> Coding diagnoses and procedures is the assignment of codes from a code set that follows the rules of the underlying classification or other coding guidelines. The current version of the ICD, [[ICD-10]], was endorsed by [[WHO]] in 1990. WHO Member states began using the ICD-10 classification system from 1994 for both morbidity and mortality reporting. The exception was the US, who only began using it for reporting mortality in 1999 whilst continuing to use [[ICD-9-CM]] for morbidity reporting. The US only adopted its version of ICD-10 in October 2015. The delay meant it was unable to compare US morbidity data with the rest of the world during this period. The next major version of the ICD, [[ICD-11]], was ratified by the 72nd [[World Health Assembly]] on 25 May 2019, and member countries have been able to report data using ICD-11 codes since 1 January 2022.<ref name=WHO-FIC_ICD11>{{cite web |title=WHO releases new International Classification of Diseases (ICD 11) |url=https://www.who.int/news-room/detail/18-06-2018-who-releases-new-international-classification-of-diseases-(icd-11)|publisher=World Health Organization |access-date=9 May 2020 |language=en}}</ref>
