ICD-10 Code L24.5 – Irritant contact dermatitis due to other chemical products (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L24.5 – Irritant contact dermatitis due to other chemical products
What it is
L24.5 identifies irritant contact dermatitis caused by exposure to chemical products other than the more specific listed agents. It refers to skin inflammation from direct chemical irritation, not an allergic reaction.
Clinical signs
Typical findings include redness, dryness, burning, itching, and sometimes cracking or scaling at the contact site. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record states irritant contact dermatitis and links it to a chemical product that is not named elsewhere in the classification. Code it only when the documentation supports a causal exposure and the dermatitis is clearly irritant in nature.
If the note names a specific chemical or describes an allergic reaction instead, choose the more precise code. Check documentation when the exposure source is vague or the diagnosis is uncertain.
Do not use for
Do not use L24.5 for allergic contact dermatitis or for irritant dermatitis caused by a specifically coded substance. If the chart does not identify a chemical cause, check documentation.
Coding tip
Look for both the dermatitis type and the exposure source; specificity in the note determines whether L24.5 applies.
