Calculate comorbidities, Charlson scores, perform fast and accurate
validation, conversion, manipulation, filtering and comparison of ICD-9 and
ICD-10 codes. Common ambiguities and code formats are handled. This
package enables a work flow from raw lists of ICD codes in hospital
billing databases to comorbidities. ICD-9 and ICD-10 comorbidity mappings
from Quan (Deyo and Elixhauser versions), Elixhauser and AHRQ included. This
package replaces 'icd9', which should be uninstalled.
