icd9Valid

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

single logical value which determines whether the ICD-9 code provided is in short (TRUE) or decimal (FALSE) form.

short

check whether any ICD-9 code is syntactically valid

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.
