Histoplasmosis capsulati, unspecified
ICD-10 B39.3 is a billable code used to indicate a diagnosis of histoplasmosis capsulati, unspecified.
Histoplasmosis capsulati is a fungal infection caused by the organism Histoplasma capsulatum, which is commonly found in soil enriched with bird or bat droppings. The infection can be asymptomatic or can present with a range of symptoms, including fever, cough, fatigue, and chest pain. In immunocompromised patients, such as those with HIV/AIDS, cancer, or those on immunosuppressive therapy, histoplasmosis can lead to severe pulmonary disease or disseminated infection affecting multiple organ systems. Diagnosis is typically made through clinical evaluation, serological tests, and culture of the organism. Treatment often involves antifungal medications such as itraconazole or amphotericin B, especially in severe cases. The unspecified designation indicates that the specific manifestation of histoplasmosis is not documented, which can complicate treatment and management strategies.
Detailed patient history, clinical findings, and treatment response.
Patients presenting with respiratory symptoms and a history of exposure to endemic areas.
Consideration of immunocompromised status and potential for disseminated disease.
Pulmonary function tests, imaging studies, and response to antifungal therapy.
Patients with chronic cough and lung nodules on imaging.
Differentiation from other pulmonary infections and conditions.
Used when a fungal infection is suspected and requires confirmation.
Document the reason for the culture and any prior treatments.
Infectious disease specialists may order this more frequently.
Common symptoms include fever, cough, fatigue, chest pain, and in severe cases, respiratory distress or systemic symptoms.
Diagnosis is made through clinical evaluation, serological tests, and culture of the organism from respiratory secretions or tissue samples.
Treatment options include antifungal medications such as itraconazole for mild cases and amphotericin B for severe cases.
