Clinical notes
Excludes1 (not coded here)
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).
Use additional code
This code represents an underlying condition. When a related manifestation is also present, coding convention calls for an additional code to be listed after this one.
