Acute pulmonary histoplasmosis capsulati

This code signifies an acute infection of the lungs caused by the fungus Histoplasma capsulatum. It typically presents with flu-like symptoms, fever, cough, and fatigue, and can range from asymptomatic to severe, potentially leading to respiratory failure. The infection is acquired by inhaling spores from contaminated soil, often associated with bird or bat droppings.

Assign this code when documentation clearly indicates an acute pulmonary infection due to Histoplasma capsulatum. This diagnosis is often supported by positive fungal cultures, serological tests, or histopathological findings from lung biopsies, in conjunction with clinical signs and symptoms. Use for initial encounters or acute exacerbations of this specific fungal pneumonia.

• Differentiate from chronic or disseminated histoplasmosis, which have distinct codes.
• Ensure documentation specifies "acute" to support this particular code.
• Consider an additional code for any associated complications, such as respiratory failure, if present and documented.
