Unspecified contact dermatitis due to cosmetics

This code signifies a generalized or unspecified inflammatory skin reaction resulting from direct exposure to cosmetic products. The patient presents with symptoms such as redness, itching, swelling, or blistering, but the specific type of contact dermatitis is not documented. The causative agent is known to be a cosmetic, but the exact cosmetic or its component is not identified.

Apply this code when documentation clearly indicates contact dermatitis caused by a cosmetic, but further specificity regarding the type of dermatitis (e.g., allergic vs. irritant) or the precise cosmetic ingredient is lacking. This is appropriate when the provider has not specified the nature of the dermatitis beyond "contact dermatitis." Documentation should explicitly link the skin reaction to cosmetic use.

• Do not use if the specific type of contact dermatitis (e.g., allergic, irritant) is documented; instead, use a more specific code from the L23 or L24 series.
• Ensure the documentation explicitly states "cosmetics" as the causative agent; otherwise, consider codes for contact dermatitis due to other substances.
• If the specific cosmetic substance is identified (e.g., hair dye, perfume), consider using a more specific code from the L25.x series.
