Question to the organizers (or anyone who knows). The following line is taken from Claims.csv:
00529616,1727574,340953,11593,Y2,Internal,Outpatient Hospital,23,1 day,8- 9 months,METAB3,3-4,SCS,1
The last column says that LengthOfStay is NULL because of suppression, but the LengthOfStay field says "1 day". This is the only such inconsistency in the entire file. Is there a chance the SupLOS field have been shifted or otherwise been misplaced? If I understand correctly, this field didn't exist in the first data set.
