The public domain modified ICD-10 classification as published in the public
domain by the US CDC. Currently this has a slightly different structure to
icd9cm_hierarchy because the published data helpfully has a
leaf flag indicating whether a code is a billable leaf node, or
a code higher in the hierarchy which nevertheless will have a description.
http://www.cdc.gov/nchs/icd/icd10cm.htm
Format: data frame, with columns for code, leaf status (0 or 1), short and long descriptions.
There are annual revisions to this data in the US.
