Tonsillar aspergillosis

This code signifies a fungal infection of the tonsils caused by Aspergillus species. It presents as an inflammatory process within the tonsillar tissue, often leading to symptoms like sore throat, dysphagia, and tonsillar hypertrophy. The infection can range from localized inflammation to more invasive forms, particularly in immunocompromised individuals.

Assign this code when documentation explicitly states a diagnosis of tonsillar aspergillosis, confirmed by microbiological culture, biopsy, or other definitive diagnostic methods. This code is appropriate for both acute and chronic presentations of Aspergillus infection localized to the tonsils.

• Ensure documentation specifies Aspergillus as the causative organism and the tonsils as the affected site.
• Do not confuse with other fungal tonsillitis (e.g., candidiasis) or bacterial tonsillitis.
• Consider an additional code for the patient's underlying immunocompromised state, if applicable, as this often predisposes to aspergillosis.
