decimal form ICD-9 codes are not ambiguous if the leading zeroes
are dropped. Some short-form ICD-9 codes would not be ambiguous, e.g. "1"
but many would be problematic. This is the inverse of
icd9AddLeadingZeroesDecimal
.
Invalid codes have no guaranteed result, and may give NA, or a (possibly valid) code in repsonse.

icd9 |
is a character vector or factor 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". |
