cTAKES uses UMLS codes that are subset to sources like SNOMED CT and RxNORM augmented with synonyms. If you are interested in ICD-9 codes, you might be able to use the UMLS CUI to map to the ICD-9 code.
Hope this helps. --Guergana From: Prasanna Bala [mailto:[email protected]] Sent: Friday, April 11, 2014 3:41 AM To: [email protected] Subject: Re: ICD9 code resolving.. Hi, I was reading a mail from the cTakes user group the other day where it was mentioned that cTakes uses ICD9 code internally. But then write the output for SNOMED CT code. I have certain entities for which I need to find out ICD9/10 codes. For eg: Consider the disease "DIABETES MELLITUS". There are so many ICD codes present for this illness. I need to narrow down to fewer ICD codes. Is it possible to automate this type of problem using cTakes. I also found that SNOMED CT code can be mapped to ICD codes. How reliable is this ? Also I have implemented another version of lookup table for matching UMLS semantic types using trie structure. I found this to be pretty fast although I implemented in python. I would like to contribute this to cTakes because this can improve the efficiency of the lookup process too. Please let me know your thoughts. Thanks for response.

Hi, I have some clarifications regarding ICD9 code. I found that cTakes uses different mapping technique to resolve the entities from the diagnosis. I want to know how they are doing this for ICD9. When I run the code, in the output it is showing the various tagged entities with SNOMED CT code. But my question, why I am not able to access the ICD9 code. I found that ICD9 code is used internally by the cTakes for finding the entities. How can I find the IC9 code for the entities ? Can you please tell me if there is any module which is using ICD9 code in the cTakes. I need to pipeline the ICD9 code also separately. Regards, Prasanna
