ICD purpose and uses

As a classification and terminology ICD-11:

  • Morbidity coding and reporting incl. Primary care
  • Casemix/DRG

ICD History

Origins of the classifications of causes of death and diseases date back to the 18th century (Sauvages’ Nosologia Methodica, Linnaeus’ Genera Morborum, Cullen’s Synopsis Nosologiae Methodicae).  

The latest revision of the ICD, ICD-11, was adopted by the 72nd World Health Assembly in 2019 and came into effect on 1st January 2022. The ICD-11 integrates the different modifications and adaptations of ICD-10, reflects the current global clinical needs, ensures long-term comparability of the data, and provides standardized solutions for the digital era we all live in.
