Calculate comorbidities, and 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.
