After the vocabulary update of Aug 29 2022 that included ICD10CM, I noticed that the number of mappings of ICD10CM codes to standard concepts is slightly reduced (in particular from 129171
standardization ‘Maps to’ relations from ICD10CM codes in the 2022-06-22 vocabulary to 127616 on all the versions after 2022-08-29).
More over, there are now important ICD10CM codes with no mapping to snomed (or any other of the vocabularies that get downloaded by default on Athena). For instance the C78* and C79* ICD10CM codes which did have a standardization mapping to snomed but not anymore.
Am I missing something?
