This command, based on a SAS program written by Dr. Hude Quan (Quan H et al. Coding algorithms for defining comorbidities in ICD-9-CM and ICD-10 administrative data. Medical Care 2005 Nov; 43(11):1073-1077.), calculates the Charlson index of comorbidity from data containing ICD-9-CM, ICD-10 or Enhanced ICD-9-CM comorbidity diagnoses codes. The Charlson score reflects the cumulative increase in likelihood of one-year mortality due to the severity of the effect of comorbidities.
