Mappings Updates
A mapping links a CIEL concept to a code in another terminology (SNOMED CT, ICD-10, ICD-11, RxNorm, ATC, LOINC, CVX and others). CIEL currently has 
The three most important are:
| Type | Meaning |
|---|---|
SAME-AS |
The codes mean the same thing |
NARROWER-THAN |
The target is more specific than the CIEL concept |
BROADER-THAN |
The target is more general than the CIEL concept |
Other types describe clinical relationships, such as associated finding, finding site, causative agent or severity. Some concepts need more than one code to be expressed fully (post-coordination), notably with ICD-11 and SNOMED CT.
- New mappings. Suggestions, from curators, files or the OCL Mapper, are held aside, reviewed by a curator, and only then added to CIEL.
- Retired codes. When a reference terminology retires a code, CIEL finds the concepts that use it and updates the mapping.
- Relationship review. SAME-AS mappings to reference codes are kept distinct from non-SAME-AS ones, and checked more strictly.
- Quality checks. Every mapping change passes Quality Assurance.
- Release. Updates ship in the next monthly release.
AI can propose and rank candidates. A human reviews every mapping before it is saved.
