ICD-10 Code B42.7 – Disseminated sporotrichosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B42.7 – Disseminated sporotrichosis
What it is
Disseminated sporotrichosis is a widespread fungal infection caused by Sporothrix species. It means the infection has spread beyond the original skin site to multiple areas or organs.
Clinical signs
Clinical features vary; refer to documentation. Commonly, you may see multiple skin lesions, nodules, or ulcerations, and sometimes deeper tissue or systemic involvement.
When to use this code
Use B42.7 when the provider documents disseminated sporotrichosis, systemic spread, or infection involving more than one body site. Code it when the record clearly distinguishes dissemination from localized cutaneous disease. Check documentation if the extent is unclear.
Do not use for
Do not use this code for localized sporotrichosis limited to skin, lymphatic, or pulmonary involvement unless dissemination is specifically documented. Check documentation if the diagnosis is only suspected.
Coding tip
Confirm the word “disseminated” in the assessment or final diagnosis before assigning B42.7.
