    ICD-10-CM Code For Paracoccidioidomycosis: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group B41 includes diagnoses for paracoccidioidomycosis, a systemic fungal infection caused by Paracoccidioides species that can present with pulmonary, mucocutaneous, cutaneous, and disseminated manifestations. These ICD-10-CM diagnosis codes are used to document clinical scenarios such as localized pulmonary disease, mucocutaneous lesions, or disseminated infection involving multiple organ systems, capturing disease severity and organ involvement. Accurate coding within the ICD-10-CM B41 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

    ICD-10-CM B41: Paracoccidioidomycosis Overview

    The ICD-10-CM B41 group covers paracoccidioidomycosis, a systemic fungal infection that primarily affects the lungs and mucocutaneous tissues. These diagnoses represent infection by Paracoccidioides species and can involve pulmonary, cutaneous, mucosal, and disseminated disease. Accurate coding matters for clinical documentation and reimbursement because it captures disease severity, organ involvement, and the need for specific antifungal therapy.

    When to Use

    Use a code from this group when a clinician documents paracoccidioidomycosis or when diagnostic testing confirms infection with Paracoccidioides species. Select the code that reflects the documented site(s) of infection and whether the disease is localized or disseminated.

    Typical Clinical Scenarios

    • A 35-year-old male agricultural worker from an endemic rural area presents to the emergency department with progressive fever, productive cough, pleuritic chest pain, and acute respiratory distress. Chest imaging shows bilateral pulmonary infiltrates and multiple nodular lesions; sputum and serologic testing confirm Paracoccidioides infection causing primary pulmonary disease requiring hospital evaluation. Typical codes: B41.0, B41.9
    • A 48-year-old female with a several-month history of weight loss, mucosal ulcers in the oral cavity, cervical lymphadenopathy, and chronic hoarseness is evaluated in outpatient infectious disease clinic. Biopsy of an oral lesion demonstrates Paracoccidioides organisms and the clinical picture reflects chronic mucocutaneous involvement with systemic symptoms, prompting assignment of a chronic paracoccidioidomycosis code. Typical codes: B41.7, B41.8
    • A 60-year-old man with known diabetes presents for management of disseminated fungal infection with cutaneous nodules, bone pain, and evidence of extrapulmonary spread on imaging after prior pulmonary disease. Because the infection involves multiple organ systems beyond the lungs and requires coordination of inpatient and outpatient care for complications, a disseminated paracoccidioidomycosis code is used to capture the systemic nature of the illness. Typical codes: B41.8, B41.9
