Toxoplasma meningoencephalitis

This code describes an infection of both the brain and its surrounding membranes (meninges) caused by the parasite Toxoplasma gondii. It represents a severe manifestation of toxoplasmosis affecting the central nervous system.

Use this code when documentation confirms inflammation of both the brain parenchyma and meninges due to Toxoplasma gondii. This is frequently seen in immunocompromised individuals, such as those with HIV/AIDS, or in congenital cases. Supporting documentation includes imaging (MRI/CT showing lesions), CSF analysis, and serological tests confirming toxoplasmosis.

• Always code the underlying condition, such as HIV, first if applicable.
• Distinguish from other forms of CNS toxoplasmosis, such as cerebral toxoplasmosis without meningeal involvement.
• Ensure provider documentation explicitly states both "meningitis" and "encephalitis" or "meningoencephalitis" due to Toxoplasma.
