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).

  • fever of unknown origin following delivery (O86.4)
  • obstetric pyemic and septic embolism (O88.3-)
  • puerperal septic thrombophlebitis (O86.81)

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.

  • genital tract infection following delivery (O86.1-)
  • sepsis during labor (O75.3)
  • urinary tract infection following delivery (O86.2-)
