Billable

Nonrheumatic aortic (valve) insufficiency

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

What This Code Means

The aortic valve does not close properly, allowing blood to leak backward into the left ventricle during diastole.

Coding Tips

  • •Verify nonrheumatic cause; rheumatic aortic insufficiency uses code I06.1.
  • •Document the severity and etiology (e.g., degenerative, endocarditis-related) to support clinical management decisions.
