This is different from syntactic validity: it looks it up in the
canonical list of ICD-9 codes published by the CMS, and which are included
in this package under extdata. Checking syntactic validity using
link{icd9IsValid} etc. is still useful, with a changing list of
icd-9 codes over time, and possible imperfections in the master lists
derived from CMS.

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"
single logical value which determines whether the ICD-9 code provided is in short (TRUE) or decimal (FALSE) form. Where reasonable, this is guessed from the input data.
single logical, if TRUE will consider a three-digit
code to be real, even though the majority of three-digit codes aren't
billable (which is at present synonmous with 'realness').
