Precoordinated expressions consist of a single
concept identifier, followed optionally by any term that is associated with that
concept. While the use of a term is not mandated, it is often preferable to include
preferred term from an appropriate dialect within the expressions to improve the human-readability
of the expression. For example:
73211009
|
Diabetes mellitus|
As mentioned, the syntax does not require a term to be used with each concept identifier,
so the following is also a valid
expression:
73211009
|
diabetes mellitus|
