Question: How does the OHDSI vocab team handle context-specific mappings between SNOMED and ICD-10-CM?
Background info: The mappings published by the NLM between those two vocabs include lots of “context-dependent mappings,” like SNOMED code A maps to ICD-10-CM code B, but only if the patient is female and has conditions C, D, or E. In those cases, you can’t really map it without knowing the specific use case.
Even if the “context-dependent” label is stored as a Class in the concept table, how does that shake out in Atlas or Athena, unless you’re paying really close attention? For example–do these context-specific mappings end up buried deep in lists of descendants, where they may (or may not) be inappropriate based on context?
I feel like a user who is really attuned to vocab issues might be able to sort this stuff out, but I’m thinking about the users who just click the “Descendant” box and go on their merry way. Although, perhaps trying to fix user behavior is not a concern for the vocab team.
Really appreciate any insight on this topic!
