Mycetoma
A chronic progressive subcutaneous infection caused by species of fungi (eumycetoma), or actinomycetes (actinomycetoma). It is characterized by tumefaction, abscesses, and tumor-like granules representing microcolonies of pathogens, such as MADURELLA fungi and bacteria ACTINOMYCETES, with different grain colors.
About the B47 Code Range
ICD-10 code B47 covers mycetoma, a chronic infection characterized by swelling and formation of nodules, primarily affecting the skin, subcutaneous tissues, and sometimes bones. These codes specify the type of mycetoma, distinguishing between infections caused by fungi or bacteria.
The code B47.0 is used for eumycetoma, a fungal infection caused by various fungi such as Madurella mycetomatis or Exophiala jeanselmei. This type is also known as eumycotic mycetoma or cutaneous alternariosis. In contrast, B47.1 identifies actinomycetoma, a similar infection but caused by bacterial organisms like Streptomyces somaliensis or Nocardia. Actinomycetoma is often referred to as Madura foot, reflecting its tendency to affect the foot. When the specific cause is not determined, coders use B47.9 for unspecified mycetoma. These distinctions are important for accurate diagnosis and treatment documentation.
