ICD-10 Code L24.1 – Irritant contact dermatitis due to oils and greases (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L24.1 – Irritant contact dermatitis due to oils and greases
What it is
This code identifies irritant contact dermatitis caused by exposure to oils or greases. It describes a non-allergic skin reaction from direct contact, usually where the substance touched the skin.
Clinical signs
Typical findings include redness, dryness, scaling, burning, itching, or cracking at the contact site. Clinical features vary; refer to documentation.
When to use this code
Use L24.1 when the record states dermatitis is due to oils, greases, or similar greasy industrial substances. It fits cases where the clinician documents an irritant reaction rather than an allergy. If the exposure is not clearly specified, check documentation.
Do not use for
Do not use this code for allergic contact dermatitis or dermatitis from other specific irritants. If the cause is unknown or not documented, check documentation.
Coding tip
Code the documented cause exactly and confirm the reaction is irritant, not allergic.
