6.1 Simple Expression


Precoordinated expressions con= sist of a single concept= identifier, followed optionally by any term that is associated with t= hat concept. While the u= se 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-readabi= lity of the expression. For example: 73211009 |Diabetes mellitus|As mentioned, the syntax do= es not require a term to be used with each concept identifier, so the = following is also a valid expression: 73211009 |diabetes mellitus|
