Clinical notes

Code first

This code represents a manifestation of an underlying disease. Coding convention requires the underlying (etiology) code to be sequenced first, with this code listed second.

  • underlying condition, such as:
  • heatstroke (T67.0-)
  • injury and trauma (S00-T88)

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).

  • sepsis- code to infection
  • severe sepsis (R65.2)
