Meningococcal endocarditis

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

What This Code Means

This is a serious infection of the heart's inner lining (endocardium) caused by meningococcal bacteria. It's a life-threatening condition that requires immediate medical treatment with antibiotics.

Coding Tips

  • •Verify that the endocarditis is specifically documented as meningococcal in origin; do not assume meningococcal infection without explicit documentation
  • •This code should be used in conjunction with codes identifying the specific valve(s) affected if documented (e.g., aortic, mitral, tricuspid, or pulmonary valve involvement)
