Blastomycosis

This code represents blastomycosis, a systemic fungal infection caused by Blastomyces dermatitidis. It primarily affects the lungs but can disseminate to other organs, including the skin, bones, genitourinary tract, and central nervous system. The infection typically results from inhaling fungal spores found in moist soil and decaying wood.

Use this code when documentation confirms a diagnosis of blastomycosis, whether pulmonary, disseminated, or cutaneous. This includes cases identified through culture, histopathology, or serological testing. Clinical scenarios include patients presenting with pneumonia-like symptoms, skin lesions, or osteomyelitis in endemic areas.

• Specify the site of infection if known (e.g., pulmonary, cutaneous, disseminated) using additional codes if available in the code set.
• Distinguish from other fungal infections like histoplasmosis or coccidioidomycosis, which have distinct codes.
• Ensure documentation clearly states the diagnosis of blastomycosis, not just suspected fungal infection.
