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).

  • asphyxia due to carbon monoxide (T58.-)
  • asphyxia due to foreign body in respiratory tract (T17.-)
  • birth (intrauterine) asphyxia (P84)
  • hyperventilation (R06.4)
  • traumatic asphyxia (T71.-)

Excludes2 (not included here)

An Excludes2 note means the excluded condition is not part of this one, but a patient can have both at the same time — in that case both codes may be reported together.
