Dear all,
I am using the (ssc install) charlson command to calculate the Charlson Comorbidity Index (CCI). I aim to compute each patient's CCI while applying the hierarchy of comorbidities (assign0). However, it seems that when a single patient has multiple records, the assign0 option does not assign the more mild form of a comorbidity to 0. Could I have overlooked something in the setup or usage of the command? Any advice would be greatly appreciated.

Code:
clear input int id str5(ICD9_1 ICD9_2) 1 "5712" "" 1 "5724" "" 2 "5712" "5724" end charlson ICD9_1 ICD9_2, idvar(id) index(c) assign0 li id weightch9 weightch15 charlindex
