Irritant contact dermatitis due to cosmetics

This code signifies an inflammatory skin reaction resulting from direct exposure to an irritating substance found in cosmetic products. It is characterized by symptoms such as redness, itching, burning, and sometimes blistering, localized to the area of contact. This is a non-allergic reaction, meaning the immune system is not involved.

Apply this code when documentation clearly indicates a contact dermatitis caused by a cosmetic product, and the reaction is identified as irritant rather than allergic. This typically occurs after initial exposure or repeated exposure to a substance that directly damages the skin. Supporting documentation should specify the cosmetic as the causative agent and rule out an allergic mechanism.

• Differentiate carefully between irritant and allergic contact dermatitis; allergic reactions to cosmetics are coded differently.
• Ensure the documentation specifies the cosmetic product as the causative agent.
• Consider an additional external cause code (e.g., W57.XXXA) to identify the specific type of cosmetic if known and documented.
