I am trying to match ICD10 codes with SNOMED. Using the relationship id “Is a” and “Maps to” I was able to match both diagnosis and procedures ICD10 codes with SNOMED.
However, when I analised the matches, I noticed that I had lost some information (e.g. the procedure laterality) with the SNOMED codes. For example, the ICD10 code for Ultrasonography of Left Hand (BP4PZZZ) gives me two SNOMED codes 1 – 303924009 (US scan of hand) and 2 – 427462007 (Ultrasound of bone). With these two codes I lost the information about the laterality of the procedure and when I search in SNOMED list, I find that SNOMED also has this code 1121000087102 (Ultrasonography of left hand) and with this code I wouldn’t lose the information about the laterality. The problem is that in the concept relationship table I don’t have any line that connects the concept ids of the ICD10 code (BP4PZZZ) that has the concept id = 2789914 and the more detailed SNOMED code (1121000087102) that has the concept id = 42534939. There is any way that I can link these two codes and all the codes that have a more specific code in SNOMED?
Thanks in advance,
