ICD-10-PCS is the annually-updated set of procedure codes designed by 3M for the US CMS. There is no directory of WHO ICD procedure codes.
Format: A named list of data frames. The elements of the list are named by
the year, e.g., "2018". Each data frame contains two character
columns, the first, named code is the procedure code; the second,
named desc, has the description.
