ICD (International Classification of Diseases) developed by the WHO (World Health Organization) is used for the systematic recording, analysis, interpretation, and comparison of mortality and morbidity data among the UN member countries and now is in its 11th revision (ICD-11).  However, the US still uses ICD-10 (ICD-10-CM). What could be its reason? Are there two versions of ICD (ICD-10 & ICD-11) used in the US simultaneously for two different purposes?  What are they? Is the latest version of ICD currently being used by UN member countries? Does such discrepancy in the ICD usage affect the comparative morbidity and mortality data processes? How? Why is important to have a correct picture of the comparative data for the USA, the UN members, and the WHO members?
