Allergic contact dermatitis due to plants, except food

This code represents an inflammatory skin reaction resulting from direct contact with allergenic substances found in plants, excluding those ingested as food. It manifests as an eczematous rash, often characterized by erythema, papules, vesicles, and pruritus, localized to the area of exposure. This condition is a delayed-type hypersensitivity reaction.

Apply this code when documentation specifies contact dermatitis caused by exposure to plants such as poison ivy, poison oak, or other botanical irritants, and the reaction is confirmed to be allergic in nature. Use when the patient presents with characteristic skin lesions following direct contact with plant material, and the provider explicitly diagnoses "allergic contact dermatitis due to plants."

• Differentiate from irritant contact dermatitis; this code specifically requires an allergic etiology.
• Ensure the documentation clearly states "due to plants" and not a generalized environmental allergen.
• Review for any associated systemic symptoms or secondary infections, which would require additional coding.
