Enteroviral encephalitis

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

What This Code Means

This is a brain inflammation caused by enterovirus infection, which is a type of virus that commonly affects the digestive system but can spread to the brain. Symptoms may include fever, headache, confusion, and in severe cases, seizures or loss of consciousness.

Coding Tips

  • •Verify the specific enterovirus type if documented (such as Coxsackievirus or Echovirus) as this may allow for more specific coding with a fifth character
  • •Ensure the diagnosis specifies encephalitis (brain inflammation) rather than meningitis or other CNS involvement, as these have different codes
