@roger.carlson an ICD10CM concept can have more than one (2-4) “Maps to” relationship in a case when there is no a full SNOMED equivalent. Such a combination of SNOMED concepts gives an opportunity to cover more ICD1OCM attributes (such as localisation, laterality, gender, clinical course, morphological peculiarities, some circumstances, etc.) and reflect the meaning of a source concept as accurate as possible. So, it is correct to list all standard SNOMED concepts mapped from each ICD1OCM concept you need.
