Irritant cntct derm due friction or cntct w oth body fluids

This code describes an inflammatory skin reaction resulting from direct irritation caused by friction or exposure to specific bodily fluids, excluding those classified elsewhere. It manifests as erythema, pruritus, and possibly vesiculation or scaling in the affected area. The dermatitis is non-allergic, meaning it does not involve an immune system response to an allergen.

Apply this code when documentation clearly indicates irritant contact dermatitis due to mechanical friction (e.g., rubbing, chafing) or contact with body fluids such as saliva, urine, or wound exudate, when these are specified as the irritant. This is appropriate when the irritant is not a chemical, drug, food, or plant.

• Ensure the documentation specifies "irritant" contact dermatitis and identifies friction or a specified body fluid as the cause.
• Differentiate from allergic contact dermatitis (L23.-) and unspecified contact dermatitis (L25.-).
• Code the specific body fluid or type of friction if further detail is provided and a more specific code exists.
