Billable

Meningococcal carditis, unspecified

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

What This Code Means

This code describes inflammation of the heart caused by meningococcal bacteria infection, when the specific type of heart involvement is not specified. Meningococcal carditis is a serious complication of meningococcal disease that affects the heart muscle or its surrounding tissues.

Coding Tips

  • Use this code only when the documentation indicates meningococcal carditis but does not specify whether it involves endocarditis, myocarditis, or pericarditis; if the specific type is documented, use the more specific A39.51, A39.52, or A39.53 codes instead
  • Ensure that meningococcal infection is confirmed in the medical record; this code should be paired with documentation of the systemic meningococcal disease and any sepsis codes if applicable
