G04.2
BillableBacterial meningoencephalitis and meningomyelitis, not elsewhere classified
This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
This code describes a serious brain and spinal cord infection caused by bacteria, where inflammation affects both the brain tissue and the membranes surrounding the brain and spinal cord. It is used when the bacterial infection doesn't fit into other more specific meningitis categories.
Coding Tips
- •Always attempt to identify the specific causative organism (such as Streptococcus pneumoniae, Neisseria meningitidis, or Haemophilus influenzae) and code it first, as this provides more clinical specificity than the unspecified code G04.2
- •Verify that the documentation clearly indicates bacterial etiology rather than viral or other causes; if the organism is not identified, confirm with the provider before defaulting to this unspecified code
