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).

assault by:
submersion (X92.-)
use of weapon (X93-X95, X99, Y00)
