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).

  • malignant neoplasm of cranial nerves (C72.2-C72.5)
  • retrobulbar malignant neoplasm (C69.6-)
