list of annual versions of billable leaf nodes of ICD-9-CM
Description
These are derived from the CMS published updates, with versions 23 to 32
currently available going back to 2004/5. The source files back to version 27
have short and long descriptions. The short descriptions are in ASCII with no
special characters, whereas the long descriptions contain accented characters
which seem to be interpreted as Unicode, latin-1 or cp1252.
This all done during package creation, but can be repeated by package users,
including pulling the data from the web pages directly. Despite my best
efforts, current locale can give different results, but this packaged data is
correct, with some UTF-8 encoded strings.
Details
Format: list of data frames. Each list item is named by the version as a
string, e.g. "32". The constituent data frames have columns icd9,
shortDesc, and longDesc.
