FormularyUpdates-20210402.pptx

1.  HOIS - still talking through this one. 
2.  Rx Norm  FHIR-31579 - Getting issue details... STATUS - was a required binding and did not allow new Rx Norm codes.  Recommendation is to make it extensible so that that you can use an NDC code at firs and then when a new Rx Norm comes out, you can add that as secondary code. Searchable by either. 

Concern about this approach "opening a hole" , i.e. potential for propogation of NDC codes where RXNorm should be.  - Brian B. shares concern per chat. 

• RM: may end up differently.
  • Compounding drugs - but they do have RX Norm codes
  • Could have a max binding to RXNorm, then make sure there are codes in there that support it. 
  • For a drug that is on formulary does not have an Rx Norm code

Summary - Saul and Courtney will reach out to find specific examples where there is a drug on a formulary that does not have an RXNorm code yet 

• Follow Zulip FHIR Chat here: https://chat.fhir.org/#narrow/stream/197730-Da-Vinci.20PDex.20Drug.20Formulary/topic/NDC.2C.20RXCUI.20and.20RXNorm

Rob would like to better understand this and propose alternative options.  He is willing to bring it back to US Core where needed as well. 

Pharmacy did approved, but will hold on applying this change until we land this with the community.  

Use cases, may need a better solution.
