Histoplasmosis, unspecified
ICD-10 B39.9 is a billable code used to indicate a diagnosis of histoplasmosis, unspecified.
Histoplasmosis is a fungal infection caused by the organism Histoplasma capsulatum, which is commonly found in soil enriched with bird or bat droppings. The infection primarily affects the lungs but can disseminate to other organs, particularly in immunocompromised individuals. Symptoms may range from mild respiratory issues to severe pneumonia, and in some cases, it can lead to systemic illness. The unspecified designation indicates that the specific type or severity of histoplasmosis has not been determined. Diagnosis typically involves clinical evaluation, imaging studies, and laboratory tests, including cultures and antigen detection. Treatment often includes antifungal medications such as itraconazole or amphotericin B, especially in severe cases or for patients with weakened immune systems. Given the potential for serious complications, timely diagnosis and appropriate management are crucial.
Detailed patient history, including exposure risks and clinical symptoms.
Patients presenting with respiratory symptoms and a history of travel to endemic areas.
Consideration of immunocompromised status and potential for disseminated disease.
Pulmonary function tests, imaging results, and treatment response documentation.
Patients with chronic cough, fever, and weight loss.
Differentiating from other pulmonary infections and ensuring follow-up care.
Used when testing for Histoplasma capsulatum in suspected cases.
Document the clinical rationale for testing and any relevant patient history.
Infectious disease specialists should ensure comprehensive documentation of exposure and symptoms.
B39.9 is used when the specific type of histoplasmosis is not documented. It is important to ensure that the clinical context supports its use to avoid audit risks.
