Chromomycosis and pheomycotic abscess (B43)
ICD-10 code B43 covers chromomycosis and pheomycotic abscesses, which are fungal infections affecting various tissues including skin, subcutaneous tissue, and the brain. These codes are specifically used to identify and classify different forms and sites of these rare fungal diseases.
The codes range from B43.0, which specifies cutaneous chromomycosis caused by fungi like Cladosporium carrionii or Fonsecaea pedrosoi; also called chromoblastomycosis; to B43.1 for a pheomycotic brain abscess, representing fungal brain infections linked to phaeohyphomycosis. Subcutaneous infections like cysts and abscesses fall under B43.2. Other less common or unspecified forms are captured with B43.8 and B43.9. These codes help medical coders and healthcare providers accurately report conditions such as phaeohyphomycosis or chromoblastomycosis when determining diagnosis and treatment plans. If searching for the ICD-10 code for infections like cutaneous chromoblastomycosis or pheomycotic brain abscess, these B43 codes provide precise categorization for clinical and billing purposes.
Clinical Terms
The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.
Cerebral Phaeohyphomycosis
CNS infections caused by neurotropic dematiaceous fungi that contain melanin in their cell walls. The infections often result in BRAIN ABSCESS; ENCEPHALITIS; and MENINGITIS in patients who are often immunocompetent. The common causative fungi include members Cladophialophora bantiana, Exophiala dermatitidis, Rhinocladiella mackenziei, and Ochroconis gallopavum. R. mackenziei infection is seen almost exclusively in patients from the MIDDLE EAST.
Phaeohyphomycosis
OPPORTUNISTIC INFECTIONS caused by the dematiaceous (darkly pigmented) MITOSPORIC FUNGI of ALTERNARIA, Bipolaris, CLADOSPORIUM, Curvularia, and EXOPHIALA. These fungi have pigmented HYPHAE due to MELANIN in the cell wall. The initial subcutaneous cyst from the infection can become systemic and spread rapidly to renal, pulmonary and cerebral systems (see CEREBRAL PHAEOHYPHOMYCOSIS) in an IMMUNOCOMPROMISED HOST.
