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.

  • heart failure complicating abortion or ectopic or molar pregnancy (O00-O07, O08.8)
  • heart failure due to hypertension (I11.0)
  • heart failure due to hypertension with chronic kidney disease (I13.-)
  • heart failure following surgery (I97.13-)
  • obstetric surgery and procedures (O75.4)
  • rheumatic heart failure (I09.81)

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.

  • cardiac arrest (I46.-)
  • neonatal cardiac failure (P29.0)
