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).

  • diabetes insipidus (E23.2)
  • electrolyte imbalance associated with hyperemesis gravidarum (O21.1)
  • electrolyte imbalance following ectopic or molar pregnancy (O08.5)
  • familial periodic paralysis (G72.3)
  • metabolic acidemia in newborn, unspecified (P19.9)
