Pneumonitis due to toxoplasmosis

This code signifies inflammation of the lung tissue specifically caused by an infection with the parasite Toxoplasma gondii. It represents a pulmonary manifestation of toxoplasmosis, often seen in immunocompromised individuals.

Use this code when documentation clearly states pneumonitis and explicitly links it to a confirmed toxoplasmosis infection. This is particularly relevant in patients with HIV/AIDS, transplant recipients, or those undergoing immunosuppressive therapy who present with respiratory symptoms and positive toxoplasma serology or tissue biopsy.

• Ensure the documentation specifies "pneumonitis" and not just "pneumonia" if the distinction is clinically relevant.
• Always sequence this code after the underlying toxoplasmosis infection (e.g., 136.3 for unspecified toxoplasmosis) if the pneumonitis is a manifestation.
• Verify the etiology is clearly stated as toxoplasmosis; do not use for other parasitic or infectious pneumonitides.
