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 cutaneous mastocytosis (Q82.2)
  • histiocytic neoplasms of uncertain behavior (D47.Z9)
  • malignant mast cell neoplasm (C96.2-)
