What This Code Means

Other less common types of Aspergillus fungal infections not classified in the more specific categories.

Coding Tips

•Use this code only when the specific site or type of aspergillosis is documented but doesn't fit other B44 codes
•Include detailed documentation of the infection site and clinical presentation in the medical record

Clinical Significance

Other forms of aspergillosis captures site-specific Aspergillus infections not classified in the more specific B44 subcategories, such as sinusitis, otomycosis, or other unusual presentations. As an opportunistic infection, it signals immunocompromise and carries significant RAF weight identical to invasive forms.

Documentation Requirements

✓Specific site of infection documented (sinus, ear, wound, etc.)
✓Culture or histopathologic confirmation of Aspergillus
✓Immunocompromised status documented when present
✓Clinical presentation and symptoms specific to the affected site
✓Treatment regimen and duration documented

Commonly Confused Codes

B44.0 (Invasive pulmonary aspergillosis) - use for invasive lung disease specifically B44.2 (Tonsillar aspergillosis) - tonsillar site has its own specific code B44.9 (Aspergillosis, unspecified) - B44.89 is preferred when the site IS documented but lacks a specific code
