History of ICD
Early medical history nomenclatures Nomenclatures evolved into classification systems,
organized according to topography and later etiology Stimulus for development of ICD:
-1851 Great Exhibition, visiting statisticians interested in comparing quantity/quality of goods-1853 First International Statistical Conference in Brussels -causes of death a topic considered for comparison across nations. Succeeded by ISI, which continues to meet biennially
![Page 14: Understanding the ICD-10-CMX. Diseases of the respiratory system. J00-J99 …continues through XXI. Factors influencing health status and contact with health services (Z00-Z98) Mental](https://reader033.fdocuments.in/reader033/viewer/2022041516/5e2b61109355bb13724b782d/html5/thumbnails/14.jpg)
History of ICD, continued
1893, ISI adopted 1st edition of international classification system – the International List of Causes of Death.
By 1899, ‘Causes of Death’ in English, French, German, & Spanish languages - adopted in US, Mexico, Canada, So America, & some cities in Europe.
U.S. committed to ICD from outset.

History of ICD, continued
ICD-1 first revision 1900 (in use 1900-1909). No MBD
ICD-2 1909 (1910-1920), International Classification of Causes of Sickness & Death
ICD-3 1920 (1921-1929) ICD-4 1929 (1930-1938), transfer to categories
based on etiology. ICD-5 1938 (1939-1948),practical consideration to
comparability between successive ICD versions. And then WWII occurred…….

The United Nations and the World Health Organization

WHO headquarters, Geneva, Switzerland - linked global health & global peace –
-7,000 employees

History of ICD, continued
WHO constitution ratified 1948; entrusted with ICD. ICD-6 1948 (1949-1957 ) - adopted the renamed

Comparing Timetables:The United States’ Timetable
Currently - The U.S. still uses the ICD-9-CMsystem, put into place in 1979. Not used by most countries in over two decades.
2015 – The U.S. implements the ICD-10-CM (now more than 20 years old), shortly before the rest of the world ushers in the ICD-11.

Purposes of ICD
Monitor epidemics/threats to public health/disease burden
Identify vulnerable/at risk populations Define obligations of WHO member states to
provide free or subsidized care to their populations
Facilitate access to appropriate health care services
Form basis of guidelines for care & standards of practice
Facilitate research into more effective treatments

Global Health Monitoring Reveals
Mental & neurological disorders account for greater disease burden than any category, except communicable diseases (WHO, 2008)
Depression - leading cause of years lost due to disability globally; disease burden 50% higher for females than males (WHO, 2012)
Treatment gap for serious mental disorders it is 32 - 78%, depending on disorder (Kohn et al of WHO, 2004).

F33 = Recurrent Depressive Disorder

Clinical Guidelines for ICD-10-CM
Blue Book - Clinical Descriptions and Diagnostic Guidelines (CDDG), for ICD-10, dropped for U.S.
No clinical descriptions accompany the U.S. modified versions of ICD-9-CM or ICD-10-CM.
U.S. government not publishing CDDG or Crosswalk between ICD-10 and 10-CM; advises clinicians to use current criteria in their area of health practice

Clinical Descriptions and Diagnostic Guidelines (CDDG)
A copy of the CDDG may be downloaded at http://www.who.int/classifications/icd/en/bluebook.pdf.
CDDG guidelines are general and flexible - in contrast to DSM dx criteria
Clinical judgment may be used in ICD system if symptom duration is longer or shorter than specified
CDDG is being updated for ICD-11.
