list of data frames with columns code, short_desc, and
long_desc, containing just the leaf (in USA, ‘billable’)
codes, and their descriptions.
For 2005 -- 2014, the following functions provide ICD-9-CM data:
get_icd9cm2009 and get_icd9cm2013_leaf. The
former includes three-digit ‘major’ down to the leaf/billable level,
and any intermediate descriptors, e.g. if a four-digit code is not
billable, and encompasses some five-digit codes, then the four digit code
would appear in get_icd9cm2014 but not
get_icd9cm2014_leaf.
