Title: Categorizes ICD-9-CM codes based on published comorbidity
Description: Methods to categorize ICD-9-CM codes into sensible disease
categories have been developed and published by numerous
authors.  Two of the most widely used such methods are the Deyo
adaptation of the Charlson index and the Elixhauser index.
This package has functions to categorize comorbidites into the
Deyo-Charlson index, the original Elixhauser index of 30
comorbidities, and the AHRQ comorbidity index of 29 diagnoses
(an update to the original Elixhauser method).
