I don't understand why this requires anything special at all regarding archetypes? Surely it is a composition with some sections, and in those sections might be an uncoded 'story' about the encounter, and then some other coded archetypes. If there is duplication of information, then IMHO they will need to see the duplicate information - once, as you say, they have copied the structured content into the note as text it has indeed lost its connection to the original data. I can't see how you could in good faith then indicate that any of the coded structured data is 'duplicate' information unless you could actually ensure that the text is also still present in the uncoded story - and if you can do that strong linking check with any degree of reliability then the whole problem doesn't really exist?
