Eumycetoma

This code represents a chronic, localized, subcutaneous fungal infection characterized by tumefaction, draining sinuses, and the presence of grains (microcolonies of the causative organism). It is typically caused by true fungi (eumycetes) and most commonly affects the feet, though other body parts can be involved. The infection often leads to destruction of tissue, including bone.

Use this code when documentation explicitly identifies a diagnosis of eumycetoma, distinguishing it from actinomycetoma (bacterial origin). This diagnosis is typically confirmed by microscopic examination of grains, fungal culture, or histopathology. Clinical presentation alone, without laboratory confirmation of fungal etiology, may not be sufficient.

• Differentiate carefully between eumycetoma and actinomycetoma; the latter is bacterial and coded elsewhere.
• Look for documentation of fungal culture results or histopathological findings confirming a fungal etiology.
• Consider additional codes for specific anatomical sites of involvement or complications like osteomyelitis, if documented.
