For each ICD9CM concept there appears to be multiple entries where the only difference appears to be the removal of the “.” in the source code (V029 vs V02.9).
cat CONCEPT.csv | grep -i ‘Carrier or suspected carrier of other specified infectious organism’
44827289,Carrier or suspected carrier of other specified infectious organism,Condition,ICD9CM,ICD9CM V code,V029,20140401,20991231,
44833028,Carrier or suspected carrier of other specified infectious organism,Condition,ICD9CM,ICD9CM V code,V02.9,19700101,20991231,
As “V02.9” is the standard ICD structure, should the entries that use this format be marked as the standard concept?
Thanks,
