In doing a recent mapping exercise, my team and I found that ICD10CM code C78.89 (Secondary malignant neoplasm of other digestive organs) (concept_id = 45576340) is associated with a domain_id of ‘Measurement’. This is contrary to what we believe, which is that this code should be domain_id of ‘Condition’. This appears to be the case for several ICD codes of ‘secondary malignancies.’ Could someone clarify (i) if this is an error in the CDM or (ii) why these select ICD10 codes are encoded as measurements? A query and select results that demonstrate this issue can be found below.
Many thanks in advance!
