A87.1

Billable

Adenoviral meningitis

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

What This Code Means

This is a viral infection of the protective membranes surrounding the brain and spinal cord caused by adenovirus. It causes symptoms like fever, headache, and neck stiffness.

Coding Tips

  • Verify the causative organism is confirmed as adenovirus before coding A87.1; other viral meningitis codes (A87.0, A87.2, etc.) apply to different viral causes
  • This code should be used only for meningitis cases; if the adenoviral infection affects other sites (respiratory, conjunctivitis), use the appropriate adenoviral infection code instead
