Description
The ValueSet http://hl7.org/fhir/ValueSet/concept-subsumption-outcome has codes:
- equivalent
- subsumes
- subsumed-by
- not-subsumed
The definition of not-subsumed as:
Coding/code “A” and Coding/code “B” are disjoint (e.g. each has propeties that the other doesn’t have).
is too strong and creates a gap in the semantic space where one should not exist (the four values should be exhaustive), and “disjoint” is a much stronger statement than just “not subsumed” since the former excludes overlaps, while the latter does not.
