Rhinocerebral mucormycosis

This code represents a severe fungal infection, specifically mucormycosis, that primarily affects the paranasal sinuses, orbit, and brain. It is characterized by rapid progression and tissue necrosis, often seen in immunocompromised individuals.

Use this code when documentation clearly indicates a diagnosis of rhinocerebral mucormycosis. This typically involves findings such as black necrotic tissue in the nasal cavity or palate, orbital cellulitis, proptosis, and neurological deficits, confirmed by biopsy or culture.

• Ensure documentation specifies the rhinocerebral form of mucormycosis; other forms (e.g., pulmonary, cutaneous) have different codes.
• Always look for underlying conditions, such as uncontrolled diabetes or immunosuppression, and code them as additional diagnoses.
• Confirm the diagnosis is definitively established, not merely suspected, before assigning this code.
