Sporotrichosis (B42)

ICD-10 code B42 groups diagnoses of sporotrichosis, a fungal infection caused by Sporothrix schenkii. These codes are used to document various manifestations of this infection, ranging from skin involvement to systemic disease.

This section includes specific codes tailored to the infection's location and severity. For example, B42.0 covers pulmonary sporotrichosis, also known as extracutaneous sporotrichosis affecting the lungs. The code B42.1 is for lymphocutaneous sporotrichosis, the most common form presenting with skin and lymph node lesions. B42.7 captures disseminated sporotrichosis, where the infection spreads widely, sometimes described as disseminated cutaneous mycosis. Other codes, like B42.81 for cerebral sporotrichosis (fungal meningitis) and B42.82 for sporotrichosis arthritis, address rarer manifestations involving the brain or joints. The unspecified code B42.9 is used when sporotrichosis is diagnosed but not specified beyond the general infection. Using these codes correctly helps identify the precise form of sporotrichosis for clinical and reporting purposes.

Clinical Terms

The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.

Sporothrix

A mitosporic Ophiostomataceae fungal genus, whose species Sporothrix schenckii is a well-known animal pathogen. The conidia of this soil fungus may be inhaled causing a primary lung infection, or may infect independently via skin punctures.

Sporotrichosis

The commonest and least serious of the deep mycoses, characterized by nodular lesions of the cutaneous and subcutaneous tissues. It is caused by inhalation of contaminated dust or by infection of a wound with SPOROTHRIX.
