Paracoccidioidomycosis
A mycosis affecting the skin, mucous membranes, lymph nodes, and internal organs. It is caused most often by Paracoccidioides brasiliensis. It is also called paracoccidioidal granuloma.
About the B41 Code Range
ICD-10 code B41 covers paracoccidioidomycosis, a fungal infection caused by Paracoccidioides species. These codes are used to diagnose and classify different forms of this infection, ranging from lung involvement to widespread disease affecting multiple organs.
The ICD-10 code for paracoccidioidomycosis includes specific categories such as B41.0 for pulmonary paracoccidioidomycosis, which involves the lungs and may present as pulmonary fibrosis due to this fungal infection. B41.7 identifies disseminated paracoccidioidomycosis, where the infection spreads beyond the lungs. Other forms are captured under B41.8, covering mucocutaneous, lymphatic, visceral, and central nervous system involvement—synonymous with terms like mucocutaneous paracoccidioidomycosis and extrapulmonary infection. When the type of paracoccidioidomycosis is not specified, B41.9 is used, which includes acute juvenile forms and related systemic effects. Using these codes helps medical professionals accurately document fungal infections caused by Paracoccidioides, improving diagnosis, treatment tracking, and epidemiological reporting.
