Negation, Null Flavours and Degree of Certainty

@Jeremy Rogers

See discussion page:  Flavours of Null and Degrees of Certainty

See also https://build.fhir.org/extension-iso21090-nullflavor.html  (RH says not really used, see http://build.fhir.org/codesystem-data-absent-reason.html instead - note used for Observation and not Condition.   Also extension which allows for http://build.fhir.org/valueset-data-absent-reason.html 

Note that the context for "why is there no data here" could relate to either a clinical context eg patient was not asked, or could be a machine/system statement eg not applicable in this setting / not specified.   Note that this does not necessarily indicate a process failure.  Not asking a question could be the appropriate action.  Distinction could be made between question totally not applicable and question-could-be-applicable-but-choice-made-not-to-ask.

Also question of ICD-like NOS/NEC for distinct bucket counting (eg "Other" combined with free text element, see As Text)

TODO  IG should clarify uses of Null Flavours for specific contexts.

Next meeting

Suggested to review http://build.fhir.org/observation-mappings.html (check use cases for "fit for")

2nd Week of June?
