Irritant contact dermatitis due to drugs in contact w skin

This code signifies an inflammatory skin reaction resulting from direct exposure to a medication applied topically. It is characterized by redness, itching, and sometimes blistering, occurring as a non-allergic response to the drug's chemical properties. The reaction is localized to the area of contact.

Apply this code when documentation clearly indicates a non-allergic, irritant dermatitis caused by a pharmaceutical agent coming into direct contact with the skin. This includes reactions to topical creams, ointments, patches, or solutions. Documentation should specify the drug involved and confirm the irritant nature of the reaction.

• Differentiate from allergic contact dermatitis (L23.-) where an immune response is involved.
• Requires documentation of the specific drug causing the reaction.
• Consider an additional code from T36-T50 to identify the drug if not already specified in the primary diagnosis.
