We need the equivalent of a "Scope and boundaries" section in this IG that identifies the specific other Da Vinci IGs (as well as US Core) that deal with provider-to-provider and provider-to-payer exchange.  CDex is, in many ways, a "fall-back" IG that is intended to cover those exchanges not already addressed by one of the other IGs.  As such, readers need to:

• be aware of the other IGs that also exist in this space and may be more appropriate for use in some situations
• understand the specific gaps in those other IGs that this guide is specifically intended to exist.

For example, if a payer needs data to close a gap, when do they use "Gaps in Care" and when will they need to use CDex?  When is US Core enough and when is CDex necessary?

Suggest that we author proposed language and then run it past the other groups by email and discuss any points of contention in a dedicated 30-minute session or something on one of our Monday calls
