Clinical notes

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.

  • pleural effusion in heart failure (I50.-)
  • pleural effusion in systemic lupus erythematosus (M32.13)
