Topic: Code System (Crosswalk)
Mohammad Wahid (Jun 25 2020 at 19:02):
I would greatly appreciate if someone can provide an optimal solution for cross mapping b/w the code systems (i.e. Snomed to ICD10, Snomed to LOINC, etc)? I have looked in to Terminology server, however, that requires creating the Concept map for such translation, therefore, is there an existing source for such conversion?

There are a few major projects that have mapped across codesets. For example, NLM has I-MAGIC which maps ICD10 and SNOMED. https://www.nlm.nih.gov/research/umls/mapping_projects/snomedct_to_icd10cm.html

@David Pyke Thank you!! Anything available for LONIC?

Yup, check the documentation page for the LOINC FHIR server: https://loinc.org/fhir/
There are ConceptMaps published for LOINC<->SNOMED, LOINC<->RxNorm, and others. No LOINC<->ICD yet, because that is a different kind of beast...which tests might be related to which conditions. As opposed to the linkage of a LOINC Part representing a substance to another terminology with concepts for substances.
Also, the #HAPI LOINC importer will create many of these ConceptMaps from the LOINC distribution files if you're looking to run this on your own.
There has also been some neat work to take instances of LOINC-coded FHIR lab results (as Observations) and map them to HPO terms: https://loinc2hpo.readthedocs.io/en/latest/
