What This Code Means

Lymphocytic choriomeningitis is a viral infection that causes inflammation of the membranes surrounding the brain and spinal cord, typically transmitted through contact with infected rodent droppings or urine. Symptoms include fever, headache, muscle aches, and sometimes more severe neurological complications.

Coding Tips

• •Verify the diagnosis is specifically lymphocytic choriomeningitis (LCMV) and not other forms of viral meningitis, as this distinction is important for accurate coding and epidemiological tracking
• •Document the source of exposure if known (rodent contact, contaminated food/water) as this may support medical necessity and help with public health reporting requirements
