Obsolete: 'icd9' is replaced by CRAN package 'icd'.
Calculate comorbidities, Charlson scores, perform fast and accurate
validation, conversion, manipulation, filtering and comparison of ICD-9-CM
(clinical modification) codes. ICD-9 codes appear numeric but leading and
trailing zeroes, and both decimal and non-decimal "short" format codes
exist. The package enables a work flow from raw lists of ICD-9 codes from
hospital billing databases to comorbidities. ICD-9 to comorbidity mappings
from Quan (Deyo and Elixhauser versions), Elixhauser and AHRQ included. Any
other mapping of codes, such as ICD-10, to comorbidities can be used.
