I was wondering if anyone is maintaining or knows of anyone maintaining drug
code crossmaps between
SNOMED and others such as NDC or First Data Bank. I saw reference to this
need on a HL7/SNOMED
pdf from 2004. I know for CDA we should SNOMED identifiers, but when we have
to deal other systems
that deal with NDC or some other set we need to way to maintain the links as
each set gets revised.
