I37.0

Billable

Nonrheumatic pulmonary valve stenosis

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

What This Code Means

Narrowing of the pulmonary valve (the valve on the right side of the heart that controls blood flow to the lungs) that is not caused by rheumatic fever.

Coding Tips

  • •Confirm nonrheumatic etiology; rheumatic pulmonary stenosis would be coded under I09
  • •Distinguish between isolated stenosis and stenosis with insufficiency (use I37.2 if both are present)
