L24.7 Irritant contact dermatitis due to plants, except food

Name of the Condition

• Irritant contact dermatitis due to plants, except food

Summary

Irritant contact dermatitis due to plants, except food, is a non-allergic inflammatory skin condition resulting from direct exposure to irritating plant substances. It is characterized by redness, itching, and discomfort in the affected areas, typically resolving once the irritant is removed.

Causes

The primary cause is exposure to plant-derived substances that damage the skin barrier. This may include sap, resins, or other plant components that act as irritants, rather than triggering an allergic reaction.

Risk Factors

• Occupational or recreational contact with plants (e.g., gardening, landscaping)
• Handling of plants with known irritant properties
• Pre-existing sensitive or compromised skin
• Prolonged or repeated exposure to plant irritants

Symptoms

• Redness and rash in the exposed area
• Itching, burning, or stinging sensation
• Dry, cracked, or scaly skin
• Pain or discomfort, especially with severe irritation

Diagnosis

Diagnosis is based on a physical examination and patient history of exposure to potential plant irritants. A healthcare provider may exclude other skin conditions through clinical assessment or, if needed, additional diagnostic tests.

Treatment Options

• Avoidance of the identified plant irritant
• Use of gentle, fragrance-free moisturizers to restore the skin barrier
• Topical corticosteroids to reduce inflammation (for severe cases)
• Cool compresses to alleviate discomfort

Prognosis and Follow-Up

Prognosis is generally good with removal of the irritant and appropriate care. Follow-up may be recommended to monitor healing and prevent recurrence, especially if exposure risks persist.

Complications

• Secondary bacterial infection from broken skin
• Chronic skin changes (e.g., thickening, scaling) with repeated exposure
• Discomfort or pain affecting daily activities

Lifestyle & Prevention

• Wear protective clothing (e.g., gloves, long sleeves) when handling plants
• Wash skin thoroughly after contact with plants
• Use barrier creams to reduce direct exposure
• Identify and avoid plants known to cause irritation

When to Seek Professional Help

Seek care if symptoms worsen, spread, or fail to improve with self-care, or if signs of infection (e.g., pus, increased pain) develop.

Tips for Medical Coders

Document the specific plant or plant part involved, if known, and confirm the condition is non-allergic (no prior sensitization). Ensure the code L24.7 is used when the irritant is a plant (excluding food-related exposures).
