    Description

      PRN is an important part of medication sigs. At an minimum, the existence of a Precondition for Substance Administration entryRelationship should trigger the asNeededBoolean field. More advanced mapping (such as mapping the code to asNeededCodeableConcept) could get tricky, since this is limited to a single code (per dosage instruction) in FHIR, but a CDA medication could have multiple preconditions.

      Still, sending at least the boolean would be useful and recommended.
