Introduction
On this page, all the rules & semantics for using RxNorm with FHIR are defined.
All of these are defined in terms of the default RxNorm database created (after fixes!) by the scripts provided with RxNorm
Basics
- Namespace is http://www.nlm.nih.gov/research/umls/rxnorm/
- both CUI and AUI are valid in this namespace
- The display name is
select Str from rxnconso where RXAUI = :code or (RXCUI = :code and SAB = 'RXNORM')
Filter properties
- Identifier Type Type = CUI|AUI restrict to only one type -- or should all filters only return CUIs?
- Semantic Type STY in/= [COL:]Value default column is TUI
- Source SAB in/= Value value comes from (select RSAB from rxnsab) (e.g. source = RXNORM)
- Term Type TTY in/= Value value of TTY column in rxnconso
