icd9_map_elix: Elixhauser comorbidities

In icd: Comorbidity Calculations and Tools for ICD-9 and ICD-10 Codes

Description

This data comprises the original mapping of Elixhauser's ICD-9-CM to 30 comorbidities. According to Sharabiani, this mapping provides the best long-term mortality prediction. The weaknesses of this mapping are that it is based on slightly out-dated ICD-9 codes. I have not yet verified what changes to the ICD-9-CM specification between 1998 and now would impact this mapping.
