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).
- congenital absence - see Alphabetical Index
Excludes2 (not included here)
An Excludes2 note means the excluded condition is not part of this one, but a patient can have both at the same time — in that case both codes may be reported together.
- postprocedural absence of endocrine glands (E89.-)
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.
