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).

  • postprocedural hypopituitarism (E89.3)
  • short stature due to endocrine disorder (E34.3-)

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.

  • the listed conditions whether the disorder is in the pituitary or the hypothalamus

Documentation support
