Objectives: Implementation of the International Statistical Classification of Disease and
Related Health Problems, 10th Revision (ICD-10) coding system presents challenges for
using administrative data. Recognizing this, we conducted a multistep process to develop
ICD-10 coding algorithms to define Charlson and Elixhauser comorbidities in administrative
data and assess the performance of the resulting algorithms. Methods: ICD-10 coding
algorithms were developed by “translation” of the ICD-9-CM codes constituting Deyo's (for …
