OptionalcaseOptionalcaseOptionalcodesOptionaldisplaysOptionalrefinedDX-8: translation-pack displays keyed by a REFINED WHO code (e.g. K02.1)
that refineWho may emit instead of the key's flat code. Falls back to
displays[key] when absent.
A national code overlay.
translationpacks keep the WHO codes and only localize the display (cheap: BNO-10, MKCH-10, and the dental chapter of ICD-10-GM/CIM-10).modificationpacks remap the code itself (US ICD-10-CM, added in DX-5).
