Billable

Nonrheumatic mitral (valve) annulus calcification

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

What This Code Means

Calcium deposits have formed in the mitral valve ring (annulus), which can affect valve function without being rheumatic in origin.

Coding Tips

  • •This is a specific structural finding; ensure imaging or pathology documentation supports calcification diagnosis.
  • •Use this code when calcification is the primary finding; if it causes stenosis or insufficiency, consider using those codes instead.

Code Also

  • , if applicable:
  • nonrheumatic mitral (valve) insufficiency (I34.0)
  • nonrheumatic mitral (valve) stenosis (I34.2)
