Penicillosis

This code represents penicillosis, a deep-seated fungal infection caused by species of Penicillium, most commonly Talaromyces marneffei (formerly Penicillium marneffei). It typically manifests as a disseminated infection, particularly in immunocompromised individuals, affecting various organs including the skin, lungs, liver, and spleen.

Use this code when documentation confirms a diagnosis of penicillosis, often identified through fungal cultures or histopathological examination. This diagnosis is frequently seen in patients with HIV/AIDS or other immunosuppressive conditions, especially in endemic regions of Southeast Asia.

• Ensure the documentation clearly specifies penicillosis and not another fungal infection.
• Code any associated manifestations or complications of the penicillosis, such as pneumonia or skin lesions, in addition to this code.
• Consider coding the underlying immunocompromised state (e.g., HIV infection) as a primary or secondary diagnosis, depending on the encounter's focus.
