ICD-10 Code B48.0 – Lobomycosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B48.0 – Lobomycosis
What it is
Lobomycosis is a chronic fungal skin infection caused by Lacazia loboi. It usually affects exposed skin and can persist for years if not recognized.
Clinical signs
Typical findings include slowly enlarging, firm nodules, plaques, or keloid-like lesions on the skin. Clinical features vary; refer to documentation.
When to use this code
Use B48.0 when the provider documents lobomycosis, lacaziosis, or a confirmed infection due to Lacazia loboi. Apply it for cases described as chronic cutaneous fungal disease with compatible clinical findings. Check documentation if the record only notes a suspected fungal lesion.
Do not use for
Do not use this code for other fungal skin infections, such as tinea or candidiasis, unless lobomycosis is specifically documented. Avoid it when the diagnosis is uncertain or when only a skin nodule is described.
Coding tip
Code B48.0 only when the chart clearly names lobomycosis or Lacazia loboi; otherwise, query for clarification.
