B40 - Blastomycosis
ICD-10 B40 is a billable code used to indicate a diagnosis of b40 - blastomycosis.
Blastomycosis is a systemic fungal infection caused by the dimorphic fungus Blastomyces dermatitidis. This organism is primarily found in soil and decaying organic matter, particularly in areas near water bodies in North America. The infection typically occurs when spores are inhaled, leading to pulmonary involvement, but it can disseminate to other organs, including the skin, bones, and central nervous system. Symptoms may range from mild respiratory issues to severe pneumonia, and systemic manifestations can include fever, chills, and weight loss. In immunocompromised patients, such as those with HIV/AIDS or those on immunosuppressive therapy, the risk of severe disease and dissemination is significantly increased. Diagnosis is often confirmed through culture, serology, or histopathological examination of tissue samples. Treatment typically involves antifungal medications such as itraconazole or amphotericin B, depending on the severity of the disease. Early diagnosis and appropriate antifungal therapy are crucial for improving outcomes, especially in high-risk populations.
Detailed history of exposure, clinical symptoms, laboratory results, and treatment response.
Patients presenting with respiratory symptoms, fever, and weight loss, particularly in endemic areas.
Documentation must clearly indicate the severity of the infection and any underlying immunocompromising conditions.
Pulmonary function tests, imaging studies, and response to antifungal therapy.
Patients with chronic cough, hemoptysis, or pneumonia-like symptoms.
Ensure that the documentation reflects the pulmonary involvement and any complications arising from the infection.
Used when a fungal infection is suspected and culture is needed for diagnosis.
Document the reason for the culture and any prior treatments.
Infectious disease specialists should ensure cultures are sent to appropriate labs for accurate identification.
Common symptoms include cough, fever, chills, night sweats, and weight loss. Skin lesions may also occur in disseminated cases.
Diagnosis is typically made through clinical evaluation, imaging studies, and laboratory confirmation via culture or histopathology.
Treatment usually involves antifungal medications such as itraconazole or amphotericin B, depending on the severity of the infection.
