Allergic contact dermatitis due to cosmetics

This code signifies an inflammatory skin reaction resulting from direct contact with a cosmetic product. The dermatitis is characterized by erythema, edema, papules, vesicles, and pruritus, specifically triggered by an allergic response to an ingredient within the cosmetic.

Apply this code when documentation clearly indicates a patient presents with contact dermatitis confirmed to be an allergic reaction caused by exposure to a cosmetic. This includes reactions to makeup, lotions, perfumes, hair dyes, or other beauty products. Supporting documentation should specify the allergic nature of the reaction and identify a cosmetic as the causative agent.

• Differentiate from irritant contact dermatitis; this code is specific to allergic reactions.
• Ensure the documentation explicitly links the dermatitis to a cosmetic product.
• Consider an additional code for the specific cosmetic if known and documented (e.g., T49.3X5A for adverse effect of cosmetics).
