icd9Billable


These are derived from the CMS published updates, with versions
  23 to 32 currently available going back to 2004/5. The source files back to
  version 27 have short and long descriptions. The short descriptions are in
  ASCII with no special characters, whereas the long descriptions contain
  accented characters which seem to be interpretable as unicode, latin-1 or
  cp1252. This all done during package creation, but can be repeated by
  package users, including pulling the data from the web pages directly.
  Despite my best efforts, current locale can give different results, but
  this packaged data is correct, with some UTF-8 encoded strings.

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.
