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.
