Question - I see some discussion of RxTerm in prior chats, but I'm wondering how it plays with FHIR resources. Would it be an element of a Medication resource? It certainly could be a ValueSet as a subset of the RxNorm CodeSystem, I imagine

RxTerm RxTerms is a drug interface terminology derived from RxNorm for prescription writing or medication history recording (e.g. in e-prescribing systems, PHRs).
Relative to Medication, RxTerms could be used in a user interface to look up the product and RxNorm term to populate Medication.code

Thanks @Scott Robertson. So just to confirm, RxTerm is not a code system itself on the Medication resource; it's a way to guide users to select a Medication?
Scott Robertson (Feb 24 2022 at 14:05):
@Brendan Keeler Yes. RxTerms is a subset of the structure (single table, select fields) and content (only US prescribable) of RxNorm. A convenience provided by NLM for use in product selection. NLM has a simple example of product lookup - RxTerms Demo. The RXCUI found in RxTerms is the same as that found in RxNorm. when using the RXCUI (whether found in RxTerms or RxNorm) in a FHIR instance, coding.system is always http://www.nlm.nih.gov/research/umls/rxnorm.
