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).

  • leukemic reticuloendotheliosis (C91.4-)
  • myelodysplastic syndromes (D46.-)
  • personal history of leukemia (Z85.6)
  • plasma cell leukemia (C90.1-)
