B42.1
ICD-10-CMThis code signifies a chronic fungal infection caused by Sporothrix schenckii that primarily affects the skin and subcutaneous tissues, characterized by a primary lesion followed by the development of secondary nodules along lymphatic channels. It represents a specific clinical presentation of sporotrichosis where the infection spreads via the lymphatic system.
Use this code when documentation clearly indicates sporotrichosis with lymphatic involvement, typically presenting as a chain of nodules extending proximally from an initial lesion. Supporting documentation would include physician notes detailing the characteristic lymphocutaneous lesions, often following a history of exposure to contaminated plant matter.
