Term: Elixhauser Comorbidity Index
Last Updated: 2009-10-22
A measurement tool that defines 30 comorbid (i.e., co-existing) conditions using ICD-9-CM codes. This instrument is meant to be used with large administrative data sets (Elixhauser et al., 1998). The index has been updated for use with ICD-10 coding (Quan et al., 2005).
The link below to ICD-9-CM and ICD-10 Coding Algorithms for Elixhauser Comorbidities provides a table identifying the ICD-9-CM and ICD-10 codes used by Quan et al. (2005).
