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).

  • anaplastic large cell lymphoma, ALK negative (C84.7-)
  • anaplastic large cell lymphoma, ALK positive (C84.6-)
  • mature T/NK-cell lymphomas (C84.-)
  • other specified types of non-Hodgkin lymphoma (C85.8-)
