<p>This runs quite slowly. Used too rarely to be worth optimizing
  now. This is used to build a master list of ICD-9 codes with their
  respective chapters, sub-chapters, etc.. The querying of the web page to
  get these is already done, and the results saved in the lists
  <code>icd9Chapters</code> etc which define ranges.</p>

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.
