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

short_code

<p>Non-decimal ICD-9 codes with length&lt;5 are often ambiguous. E.g.
  100 could be 1.00 10.0 or 100 if coded incorrectly. We must assume 100 is
  really 100</p>
