ICD-10 Code L24.7 – Irritant contact dermatitis due to plants, except food (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L24.7 – Irritant contact dermatitis due to plants, except food
What it is
This code identifies an irritant skin reaction caused by contact with plants that are not used as food. It covers inflammation from direct exposure, such as handling or brushing against a plant, rather than an allergic or ingested cause.
Clinical signs
Typical findings include localized redness, itching, burning, swelling, or a rash at the contact site. Clinical features vary; refer to documentation if the note does not clearly describe a plant-related irritant dermatitis.
When to use this code
Use L24.7 when the record states irritant contact dermatitis from a nonfood plant, such as after gardening, outdoor exposure, or plant handling. You should code it when the clinician documents a direct irritant reaction and does not describe a food-related exposure. If the note only says “rash” or “dermatitis,” check documentation for the plant trigger.
Do not use for
Do not use this code for allergic contact dermatitis, poison ivy if documented as an allergic reaction, or dermatitis from food plants. If the cause is unclear, check documentation before assigning L24.7.
Coding tip
Assign the code only when the plant trigger and irritant nature are both documented.
