Q23.81

Billable

Bicuspid aortic valve

This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).

What This Code Means

A birth defect where the aortic valve has two leaflets instead of the normal three, which may or may not cause functional problems.

Coding Tips

  • •Document whether the bicuspid aortic valve is hemodynamically significant or asymptomatic
  • •Note any associated aortic stenosis or insufficiency that may develop over time

Code Also

  • , if applicable, acquired aortic valve disorders, such as:
  • aortic (valve) insufficiency (nonrheumatic) (I35.1)
  • aortic (valve) stenosis (nonrheumatic) (I35.0)
  • aortic (valve) stenosis with insufficiency (nonrheumatic) (I35.2)
