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).

  • hypertension due to kidney disease (I15.0, I15.1)
  • renovascular hypertension (I15.0)
  • secondary hypertension (I15.-)

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.

  • acute kidney failure (N17.-)

Includes
