icd9AddLeadingZeroes_alt_ShortSingle

icd9_add_leading_zeroes_alt_cpp

<p>This should add leading zeroes when there is definitely no ambiguity,
e.g. V1. However V10 should not be altered, because V010 is a different
code. The goal is for this to be faster, but must be correct! Example in
<code>manip.cpp</code> has the benchmark code.</p>

manip

internal

Calculate comorbidities, Charlson scores, perform
fast and accurate validation, conversion, manipulation, filtering and
comparison of ICD-9 and ICD-10 codes. This package enables a work flow
from raw lists of ICD codes in hospital databases to
comorbidities. ICD-9 and ICD-10 comorbidity mappings from Quan (Deyo
and Elixhauser versions), Elixhauser and AHRQ included.  Common
ambiguities and code formats are handled.
