ICD-10 Code L08.1 – Erythrasma (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L08.1 – Erythrasma
What it is
L08.1 identifies erythrasma, a superficial bacterial skin infection that usually affects warm, moist skin folds. It is commonly caused by Corynebacterium and is documented as a localized cutaneous condition.
Clinical signs
Typical findings include brown-red or tan patches with fine scaling, often in the groin, axillae, or toe webs. Clinical features vary; refer to documentation for the exact site and appearance.
When to use this code
Use L08.1 when the provider documents erythrasma as the diagnosis, including localized infection in skin folds or interdigital spaces. Code it when the note clearly identifies erythrasma rather than a nonspecific rash, dermatitis, or fungal infection. If the documentation is unclear, check documentation.
Do not use for
Do not assign this code for candidiasis, tinea, intertrigo, or other non-erythrasma skin conditions. If the record only says “rash” or “intertrigo” without erythrasma, this code is not supported.
Coding tip
Confirm the provider actually names erythrasma and document the involved anatomic site when available.
