description: A logical reference (i.e. a reference to ValueSet.url) to a value set/version that identifies a set of possible coded values used to convey a higher level concept that encompasses a list of candidate specializations when there is no formal code defined for that purpose. For example, the concept of COVID preventative medications can be expressed as a value set because there is no specific code representing that concept.
