An Excludes1 note is a pure exclusion: the excluded condition and this code should never be reported together, because the two conditions cannot occur at the same time (e.g. a congenital form vs. an acquired form of the same disease).
Includes
Terms listed here further define or give examples of the conditions grouped under this code — they describe what the code covers, not a separate diagnosis.
