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).

  • neutropenic splenomegaly (D73.81)
  • primary splenic neutropenia (D73.81)
  • splenitis, splenomegaly in late syphilis (A52.79)
  • splenitis, splenomegaly in tuberculosis (A18.85)
  • splenomegaly NOS (R16.1)
  • splenomegaly congenital (Q89.0)
