ICD-10 Code L30.1 – Dyshidrosis [pompholyx] (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L30.1 – Dyshidrosis [pompholyx]
What it is
L30.1 identifies dyshidrosis, also called pompholyx, a type of eczema affecting the hands or feet. It is used when documentation describes this specific vesicular dermatitis pattern.
Clinical signs
Typical findings include small, deep-seated, itchy vesicles on the palms, sides of the fingers, or soles. Clinical features vary; refer to documentation.
When to use this code
Use L30.1 when the provider documents dyshidrosis, pompholyx, or dyshidrotic eczema. It also fits cases described as recurrent vesicular eczema of the hands or feet when the diagnosis is clear. Check documentation if the note only says “rash” or “dermatitis.”
Do not use for
Do not use this code for nonspecific eczema, contact dermatitis, or fungal infections unless dyshidrosis is specifically documented. If the condition is uncertain, check documentation.
Coding tip
Assign L30.1 only when the record names dyshidrosis or pompholyx; otherwise, code the documented dermatitis type.
