Rheumatic mitral stenosis

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

What This Code Means

Permanent narrowing of the mitral valve opening due to scarring from previous rheumatic fever, restricting blood flow from the left atrium to the left ventricle.

Coding Tips

  • •This is a chronic sequela of rheumatic fever; document the severity (mild, moderate, severe) if available
  • •Differentiate from acute rheumatic mitral involvement (I01.1) by confirming chronic/scarred presentation
