    ICD-10-CM B42: Sporotrichosis Overview

    The ICD-10-CM B42 group covers sporotrichosis, a fungal infection typically affecting the skin and subcutaneous tissues and sometimes spreading lymphatically or systemically. These diagnoses target infections caused by Sporothrix species and may involve cutaneous nodules, ulcerations, or pulmonary and disseminated disease. Accurate coding matters for reimbursement because it captures disease severity, treatment complexity, and potential need for inpatient management or antifungal therapy.
