Mixed ambiguity with conjunction:
Concept |

t | 199779004 |Persistent occipitoposterior or occipitoanterior position - delivered (disorder)| |

|
has 2 possible meanings, neither of which exist in SNOMED CT:- POSSIBLY_EQUIVALENT_TO xxxxxxxx Persistent occipitoanterior presentation and now delivered
- POSSIBLY_EQUIVALENT_TO yyyyyyyy Persistent occipitoposterior presentation and now delivered
- However, both of these are compound clinical statements that should not be added as active concepts but are required in order to satisfy the requirement to ensure clinically safe reporting of historical data.
- In addition is is necessary to resolve the conjunction that arises from the original concept.
Resolution:
- Create 2 new concepts:
-
