Meaning Unknown | No |
Additional notes:
Examples:
Semantic meaning the same but FSN different:
235998001 Perinephric abscess (disorder) - inactivated
SAME_AS
80640009 Perirenal abscess (disorder)
Both concepts had an effective date of 2002-01-31 and so the decision was based on current clinical usage and the retained concept already had a synonym of Perinephric abscess.
Identical FSN but different semantic tag:
association required | The inactivation reason “Meaning Unknown” explicitly states that the meaning of the inactivated concept (A) cannot, in the judgment of the author/editor be determined and therefore no historical association should be provided. | |
| Annotation | Additional notes on why this concept was considered not to represent a known clinical phenomenon. | |
| Dropdown list (Where no replacement is appropriate) | No suitable replacement concept identified |
Additional notes:
- Using the SCT term as a search term in PubMed may return some matches that give an indication of meaning and a return of no matches would support the use of this reason for inactivation.
- Consider consulting domain experts to establish whether the concept to be inactivated is or is not considered to have clinical meaning within their sphere of practice. Use the sub and supertypes to identify the domain to consult.
Example:
194964003 Milk spots of pericardium (disorder)
This concept has been inherited from ICD-9 via Read Codes. Some sources recognize it as a normal morphology, others as an abnormal morphology. So, as a disease entity, nobody seems to know what it means or what the case definition is.145857006 Soft tissue X-ray abnormal (situation) - inactivated
SAME_AS
168711005 Soft tissue X-ray abnormal (finding)
Managing incoming historical associations:
The intention is that this functionality will be seamlessly integrated into the tooling so as to present to the user the appropriate updated historically association to be allocated.
Note: Once MOVED_TO the NRC we (SNOMED International) have no knowledge of what has happened to BIntEdNo historical association is provided.
