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
