Do a google search for
sas Charlson Comorbidity Index
Are you familiar with CDC's HCUP NIS database? That website has macro's for charlson comorbiditity index I think so (or Elixhauser's comorbidity index).
Hi Jack. There are a number of variations on the Charlson and a lot of different code sources.
SEER publishes a version of the code but it's specific to cancer populations:
https://healthcaredelivery.cancer.gov/seermedicare/considerations/macro-2014.html
There's a Canadian group that has a lot of fantastic resources. I have heard that Canadian dx patterns and codes could differ slightly from code patterns in the US, though, so that's a caveat.

There are also versions specific to Medicare data:

Lastly, if you work for an organization that is part of HCSRN, there are standardized versions of the Charlson and other comorbidity indices available.
Hope this helps!
