The document discusses the International Classification of Diseases (ICD), which is managed by the World Health Organization (WHO) and used globally for diagnostic and health management purposes. ICD-11, released in 2018, provides major improvements including more clinically relevant classifications that reflect advances in medicine, easier coding, and a digital format. Key changes include new chapters on disorders of the immune system, blood, sexual health, and traditional medicine. ICD-11 also has enhanced functionality for research, policymaking, and clinical practice.

3. International classification of
diseases (ICD) is managed by
world health organization (WHO).
It is globally used diagnostic tool
for epidemiology, health
management and clinical
purposes.
Introduction :

4. Evolution of diseases
classification system:
Francois Boissier de Sauvages de
Lacroix
(1706) made first attempt to
classify diseases systematically
and published (1777)
classification named as “Nasolgie
methodica”.

5. Willam Far (1807-1883) He developed
more systematic and scientific way of
diseases classification.
In 1853 The International statistical
congress in “Brusses” acknowledge that a
uniform classification required. The
congress requested to Willam Far & Mark
Spine to prepare an internationally
accepted classification of causes of death.

6. In 1855 congress meeting was in paris William far
and Spine submitted their methods of
classification based on mortality and causes of
death. The congress accepted both the
classification and adapted a combined approach
included 139 rubrics.

7. Initially far’s classification was not
universally accepted. William Far’s
classification model was further revised in
1874, 1880 &1886.
In 1893 a French physician “Jacaues
Bertillion” introduced Bertillon
classification of death. At very first time
Bertillon classification received general
approach and was adapted by several
countries.

8. In 1898 American Public Health Associan (APHA)
recommended to registrar Canada, Maxico & USA to
adapt Bertillon classification of death. APHA also
recommended that this classification need to be revised
in every 10 years.
So, this classification was further revised in 1899, 1909,
1919, 1929 & 1938. These five revision had minor
corrections. But, 6th Revision was a major correction in
classification of death……..

9. In 1946 International health conference was held in
Newyork and World Health Organization took over this
classification and International Classification of Diseases
(ICD) was born.

10. ICD:
Produced by WHO.
ICD – I published in1893
ICD – 6 Produced by WHO 1948 (02 Volume)
ICD – 7 released in 1955 (Paris)
ICD- 8 released in 1965 (Genewa)
ICD – 9 released in 1975 (Genewa)
ICD – 10 released in 1st January 1993.
ICD 10 has 3 volume.
ICD 10 coding system based on alphanumerical.
ICD 11 is aligned with GLASS (Global
Antimicrobial resistance system)

11. What is ICD–11?
•International standard for systematic recording,
reporting, analysis, interpretation and comparison
of mortality and morbidity data.
•Health conditions and accidents are assigned ICD–11
codes, resulting in data that can be used by
governments to design effective public health policies,
and measure their impact, or used for clinical
recording.
• ICD is fully electronic, currently providing access to 17
000 diagnostic categories, with over 100 000
medical diagnostic index terms. The index-based
search algorithm interprets more than 1.6 million
terms.
• ICD–11 is easy to install and use online or offline,

12. Why Change ICD-10?

13. -Substantial advancement in medicine and the science of
disease have occurred over the past 30 years.
-ICD-10 is outdated both clinically and from a classification
perspective.
- Structural changes were needed to some chapters.
-Changes could not be handled under normal ICD-10
updating mechanism.
-Increasing need to operate in an electronic enviorment.

14. Improvements in ICD–
11
•Vast improvement on previous revisions. It reflects
critical advances in science and medicine, aligning
classification with the latest knowledge of disease
treatment and prevention.
• There is more meaningful clinical content than
ICD–10.
• Ease and accuracy of coding requiring less user
training than ever before, together with the availability
of online and offline functioning.
•Digital health ready, for use in multiple IT
environments.It is presented together with a suite of
web services including multilingual support and in-built
user guidance.

ICD is used by:
Doctors, Nurses, Clinical psychologist, Researchers,
Pharmacists, Hospital administrators, Policy makers,
Pharma Industries, Health coders, Biotechnologists,
Health care workers etc.

16. Utility of ICD:
• Mortality and Morbidity Reporting (Causes of death,
different diagnosis, Prevalence of illness, comparing the
illness with various region etc.)
• Cancer registry
• Anti microbial resistance (Uses of antibiotics and it’s
effect and development of guideline about uses of these
antibiotics)
• Assisting functioning and disability (development of
disability assessment scale eg: woodas)

17. Key Changes & Innovations in
ICD-11
•The global standard for health data, clinical
documentation and statistical aggregation.
• Multiple uses, including primary care.
• Thoroughly and scientifically updated, and designed for
use in a digital world.
• State-of-the-art technology reduces the costs of
training and implementation.
• Multilingual design facilitates global use while the
proposal platform allows stakeholder participation in
keeping ICD–11 up-to-date.
• Countries have already commenced preparing for
implementation of ICD–11, with both English and
Spanish versions online.

18. New Chapters in ICD - 11:
Disorders of Immune system
Disorder of Blood and blood forming organs
Conditions related to sexual health
Sleep wake disorders
Traditional medicine

19. • Coding traditional medicine (ICD also code traditional medicine
because a huge no of population in the world use traditional medicine)
• Safety and quality control
• Resources allocation and grouping
• Research and Clinical trial
• Understanding diseases
• Management of diseases

20. Approaching ICD – 11:
htpps.icd.who.int/english

Volume 1 : Tabular list
Volume 2: Reference guide
Volume 3: Alphabetical index - 2 Supplementary sections .
Section V- Supplementary sections for functioning
assessment.
Section X– Extension Codes-Severity ,Course, Onset, time
line,diagnosis certainty and diagnosis timing.

26. To Conclude ICD-11
•Although there have been significant
improvement in biological understanding of
psychatric illness but still far away from having
meaningful classificatory system based
etiology/Pathology.
•ICD-11 remain categorical approach for
diagnosis.

27. Take Home Message
•11th Revision released by WHO.
•Came into effect January 2022
•Codes are different
•Total 27 chapters,6 new chapter added.
•06 Mental ,behavioural or neurodevelopment
disorder.
•Digital Capabilities.

28. Indian Classification of mental disorder
ICD – 8 was modified and classified according
to Indian conditions by Neki (1963), Wig &
Singer (1967), Vahia (1961), Verma (1971).
Mental disorder are divided in three areas:
• Psychosis (Major Mental Disorder)
• Neurosis ( Minor mental Disorder)
• Special Disorder (Based on diseases)
