ICD-10 Code L24.8 – Irritant contact dermatitis due to other agents (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L24.8 – Irritant contact dermatitis due to other agents
What it is
L24.8 identifies irritant contact dermatitis caused by an agent not named in a more specific ICD-10 code. It refers to skin inflammation from direct irritation, not an allergic reaction.
Clinical signs
Typical findings include localized redness, dryness, burning, itching, scaling, or cracking at the exposure site. Clinical features vary; refer to documentation.
When to use this code
Use L24.8 when the record documents irritant contact dermatitis and names an unspecified or “other” irritant, such as a workplace chemical or other external agent. You should also use it when the chart clearly excludes allergy and supports a direct irritant cause. Check documentation if the agent is not stated.
Do not use for
Do not use this code for allergic contact dermatitis, atopic dermatitis, or dermatitis from a specifically listed irritant that has its own code. Do not assume the cause without documentation.
Coding tip
Confirm the irritant and whether the reaction is irritant, not allergic, before assigning L24.8.
