Coding Tips

  • •Verify the cause is nonrheumatic; if rheumatic fever history exists, use I09.9 instead.
  • •Document severity level (mild, moderate, severe) when available to support medical necessity for interventions.

Code Also

  • , if applicable:
  • nonrheumatic mitral (valve) annulus calcification (I34.81)
