Meningoencephalitis due to toxoplasmosis

This code signifies an inflammatory condition affecting both the brain (encephalitis) and the meninges (meningitis), specifically caused by infection with the parasite Toxoplasma gondii. It indicates a severe neurological manifestation of toxoplasmosis.

Apply this code when documentation clearly states a diagnosis of meningoencephalitis and explicitly links it to toxoplasmosis. This is typically seen in immunocompromised individuals (e.g., HIV/AIDS patients, transplant recipients) or in congenital cases. Supporting documentation would include positive serology for Toxoplasma gondii, neuroimaging findings consistent with meningoencephalitis, and CSF analysis.

• Ensure the documentation specifies both meningeal and cerebral involvement.
• Do not use for toxoplasmosis affecting other organ systems without neurological involvement.
• Consider additional codes for underlying conditions, such as HIV infection, if applicable.
