The Foundation Component represents the entire WHO-FIC universe. It is a multidimensional collection of interconnected entities and synonyms.
These entities consist of diseases, disorders, injuries, external causes, signs and symptoms, functional descriptions, interventions, and extension codes.
ICD-11 statistical core (MMS) is derived from this foundation, ICF and ICHI will follow.
The entities in the Foundation Component:
are not necessarily mutually exclusive
allow multiple parenting ( i. e. an entity may be in more than one branch, for example tuberculosis meningitis is both an infection and a brain disease)
ICD-11 Coding Tool is a software to help the users of coding with ICD-11
There are some differences in the way searching is performed between the Coding Tool and the ICD-11 Browser
The browser search may give you results that are groupings (or blocks) in addition to entities with codes. However, the coding tool only gives results that have codes by design.
Browser has the advanced search feature which allows you select what to search (i.e. you may search exclusions, definitions, etc.) whereas the coding tool searches only the index including the titles.
Coding tool has word completion and word suggestion.
Coding tool has chapter filtering feature which by default filters out the “Extension Codes” and the “Traditional Medicine”.
