icd9ExtractAlphaNumeric

is a character vector of ICD-9 codes. If fewer than five characters is
given in a code, then the digits are greedily assigned to hundreds, then
tens, then units, before the decimal parts. E.g. "10" becomes "010", not
"0010"

icd9

removes whitespace and separates V or E if present.

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.
