The WHO Family of International Classifications and Terminologies includes:

• the International Statistical Classification of Diseases and Related Health Problems (ICD),
  
• the International Classification of Functioning, Disability and Health (ICF),
  
• and the International Classification of Health Interventions (ICHI). 

These Reference Classifications serve as the global standards for health data, clinical documentation and statistical aggregation.

Benefits of WHO-FIC

ICD-11, ICF and ICHI are key for effective knowledge representation and data transfer.

WHO Family of International Classifications (WHO-FIC) allows all healthcare workers (and patients) to communicate using one (technical) language.

In a hyper-connected world, WHO-FIC with their shared terminology are key for supporting natural language processing (NLP).

WHO-FIC with their shared terminology are key for effective text mining or text analytics (the process of deriving high-quality information from plain and unstructured text).

Used by

• Governments to allocate resources
• Researchers to collaborate across borders
• Doctors to document their cases
• Health providers in algorithms for decision support
• Hospitals to count the frequency of health problems
• Laboratories to exchange investigative data
• Insurance companies for billing purposes
• International organizations to assess trends in public health

Derived classifications

Derived classifications are extensions of reference classifications, and are created for use within a specialty setting and are derived from the common foundation.
