Association reference set types in the International Release of SNOMED CT


Excerpt


Association reference set

Descriptions

Concept
t900000000000523009 | POSSIBLY EQUIVALENT TO association reference set |

Applies to a

Gloss
Spacetrue
tconcept
that is ambiguous. The targetComponent is an active
Gloss
Spacetrue
tconcept
that represents one of the possible meanings of the inactive
Gloss
tconcept
. Multiple rows are used to refer to each of the possible meanings of the ambiguous
Gloss
tconcept.

Concept
t900000000000524003 | MOVED TO association reference set |

Applies to a

Gloss
Spacetrue
tcomponent
that has been moved to (or are pending a move to) another namespace. The targetComponent identifies the target namespace (not the new
Gloss
tcomponent
).

Concept
t900000000000525002 | MOVED FROM association reference set |

Applies to a

Gloss
Spacetrue
tcomponent
that has been moved to this namespace from another namespace. The targetComponent identifies the original
Gloss
Spacetrue
tcomponent
Gloss
Spacetrue
tIdentifier
in its previous namespace.

Concept
t900000000000526001 | REPLACED BY association reference set |

Applies to an erroneous, obsolete and other

Gloss
Spacetrue
tinactive component
for which there is a single active replacement. The targetComponent identifies the active
Gloss
Spacetrue
tcomponent
that replaces this
Gloss
tcomponent.

Concept
t900000000000527005 | SAME AS association reference set |
 

 

Applies to a

Gloss
Spacetrue
tcomponent
that is a duplicate. The targetComponent identifies the active
Gloss
Spacetrue
tcomponent
that this
Gloss
Spacetrue
tcomponent
duplicates.

Concept
t900000000000528000 | WAS A association reference set |

Links an inactive classification

Gloss
Spacetrue
tconcept
such as "not otherwise specified" or "otherwise specified" with the active
Gloss
Spacetrue
tconcept
that was formerly its most proximal supertype.

Concept
t900000000000529008 | SIMILAR TO association reference set |

(not used currently)

Concept
t900000000000530003 | ALTERNATIVE association reference set |

Links an inactive classification

Gloss
Spacetrue
tconcept
derived from ICD-9 Chapter XVI "Symptoms signs and ill-defined conditions" with the most similar active
Gloss
tconcept.

Concept
t900000000000531004 | REFERS TO concept association reference set |

Applies to an inactive

Gloss
Spacetrue
tdescription
which is inappropriate to the
Gloss
tconcept
 it is directly linked to but instead should refer to the
Gloss
Spacetrue
tconcept
referenced by the targetComponent.

 


The following table holds example entries for the 

Concept
t900000000000526001 | Replaced by |
ShowFormatinline
reference set. With this reference set is possible to automatically identify that the inactive concept
Concept
t 696005 | Chronobiologic disorder |
ShowFormatinline
should be replaced with the concept
Concept
t387605007 | Abnormal chronobiologic state |
. This type of reference set is particularly useful for ensuring consistent use of SNOMED CT over time. The reference set mechanism here provides an easy and standardized way of managing changes to coding or documentation practice over time.
