A linearization is a subset of the foundation component, that is:
Fit for a particular purpose: reporting mortality, morbidity, or other uses
Composed of entities that are Mutually Exclusive of each other
Each entity is given a single parent
Linearizations are similar to the classical print versions of ICD Tabular List (e.g. volume I of ICD-10 or other previous editions).
Various linearizations could be built at different granularity,
use case or other purposes such as for Primary Care, Clinical Care or Research. The linkage from the foundation component to a particular
linearization will ensure consistent use of the classifications.
