Encephalitis, myelitis, and encephalomyelitis in protozoal diseases classified elsewhere

This code signifies inflammation of the brain, spinal cord, or both, specifically when caused by a protozoal infection. It indicates neurological complications arising from parasitic diseases.

Use this code when documentation clearly states encephalitis, myelitis, or encephalomyelitis due to a protozoal etiology. This typically occurs in patients with confirmed protozoal infections (e.g., toxoplasmosis, malaria) who subsequently develop central nervous system inflammation.

• Always code the underlying protozoal disease first, as this code is for manifestations classified elsewhere.
• Ensure documentation specifies "protozoal" as the cause; do not use for viral or bacterial etiologies.
• Distinguish from other forms of encephalitis/myelitis not caused by protozoa.
