Other zygomycoses

This code represents a diagnosis of zygomycosis that does not fit into the more specific categories of mucormycosis or entomophthoramycosis. These are severe, often rapidly progressive fungal infections caused by fungi within the subphylum Mucoromycotina, typically affecting immunocompromised individuals. The infection can manifest in various forms, including rhinocerebral, pulmonary, cutaneous, or disseminated disease.

Use this code when the medical record clearly documents a diagnosis of zygomycosis, but the specific type (e.g., mucormycosis, entomophthoramycosis) is not identified or is explicitly stated as "other." This code is appropriate when the physician's documentation confirms a zygomycotic infection that doesn't align with more precise classifications. Supporting documentation should include laboratory confirmation of a zygomycete and the physician's diagnostic statement.

• Ensure the documentation specifies "zygomycosis" and not a more general fungal infection.
• Always look for more specific codes within the B46 category (e.g., B46.0 for pulmonary mucormycosis) before defaulting to this code.
• Code any associated manifestations or complications of the zygomycosis, such as pneumonia or sinusitis, as additional diagnoses.
