Pheomycotic brain abscess

This code represents a brain abscess caused by a pheomycotic fungal infection. It signifies a localized collection of pus within the brain parenchyma resulting from an opportunistic fungal pathogen, often seen in immunocompromised individuals.

Apply this code when documentation explicitly states a brain abscess due to a pheomycotic fungus. Supporting documentation would include microbiology reports confirming pheomycotic species (e.g., Cladophialophora, Exophiala) from brain tissue or CSF cultures, alongside imaging (MRI/CT) consistent with a brain abscess.

• Ensure the documentation specifies "pheomycotic" or a specific dematiaceous (black mold) fungal species causing the brain abscess.
• Do not use this code for brain abscesses caused by other fungal types (e.g., aspergillosis, candidiasis) or bacterial infections.
• Sequence this code as the primary diagnosis when the pheomycotic brain abscess is the reason for the encounter.
