icd9Tell

partly implemented. Goal is to guess whether codes are short or
  decimal form, then to call icd9Explain with the condense argument.
  Currently condense works, but not with the icd9 lookup table currently in
  use. Not exporting this function until it works as intended.

This package allows accurate manipulation, validation and
    comparison of ICD-9-CM (clinical modification) codes. Although ICD-9 codes
    appear numeric, this is not the case, since trailing zeroes, and a mixture
    of decimal and non-decimal "short" format codes exist. Tools to map ICD-9
    codes to co-morbidities are also provided, with mappings from Quan (Deyo
    and Elixhauser versions), Elixhauser and AHRQ included.
