Blastomycosis, unspecified

This code represents a fungal infection caused by Blastomyces dermatitidis, affecting various body systems without further specification of the affected site. It can manifest as a pulmonary infection, skin lesions, or disseminate to other organs like bones, joints, or the central nervous system.

Use this code when blastomycosis is diagnosed, but the medical record does not specify the particular organ or system involved. This is appropriate for cases where the infection is systemic or the primary site is not clearly documented. Documentation should confirm a diagnosis of blastomycosis without further anatomical detail.

• Avoid using this code if a specific site of blastomycosis (e.g., pulmonary, cutaneous) is documented; instead, use the more specific B40.0-B40.8 codes.
• Always review the entire medical record to ensure no more specific anatomical site is mentioned before assigning this unspecified code.
• Consider any associated symptoms or complications that may require additional codes.
