Multisystemic disseminated toxoplasmosis

This code represents a severe, widespread infection caused by the parasite Toxoplasma gondii, affecting multiple organ systems throughout the body. It signifies a disseminated form of toxoplasmosis, indicating that the infection has spread beyond a localized area.

Use this code when documentation clearly indicates systemic involvement of toxoplasmosis, such as toxoplasmic encephalitis, pneumonitis, myocarditis, or chorioretinitis occurring concurrently or as part of a generalized infection. This code is typically seen in immunocompromised individuals, such as those with HIV/AIDS or organ transplant recipients.

• Always review the medical record for specific organ involvement to ensure the "multisystemic" aspect is clearly documented.
• Do not use this code for localized toxoplasmosis; specific codes exist for single-organ involvement (e.g., toxoplasmic chorioretinitis).
• Consider sequencing this code as the primary diagnosis when it is the reason for the encounter, especially in immunocompromised patients.
