implemented thus far

year

single logical value, defaults to <code>FALSE</code> in most functions.

verbose

Currently only the most recent update is implemented. Note that
 CMS have published additional ICD-9-CM billable code lists since the last
 one from the CDC: I think these have been the same every year since 2011,
 though. THe last CDC release is Dtab12.rtf from 2011.

internal

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.
