The World Health Organization (WHO) released its newest version of the International Classification of Diseases, ICD-11, on June 18, 2018. ICD is used to classify diseases, disorders, injuries and related health conditions in a consistent manner by governments and healthcare providers.
The new version has 55,000 codes, vs. 14,400 in ICD-10. It is a multilingual, searchable digital resource and can be integrated with electronic health records. There are some coding scheme differences vs. ICD-10, including a switch to Arabic numerals and the presence of a letter in the second position to differentiate ICD-11 codes from ICD-10 codes.
ICD-11 has added some new chapters, including “Diseases of the blood or blood-forming organs”, “Diseases of the immune system”, “Sleep-wake disorders”, “Conditions related to sexual health”, and others. Codes for antimicrobial resistance match up more closely with those in the Global Antimicrobial Resistance Surveillance System (GLASS).
A new code, GC51, addresses “Gaming disorder, characterized by a pattern of persistent or recurrent gaming behavior … of sufficient severity to result in significant impairment in personal, family, social, education, occupational or other important areas of functioning.”
Member states will consider the adoption of ICD-11 in May 2019, and it would go into effect on January 1, 2022. The projected release date for the ICD-11-CM version by the CDC/ National Center for Health Statistics is not available. The 2019 ICD-10-CM codes have been released, and are to be used for the period Oct. 1, 2018 through Sept. 30, 2019.
