Irritant contact dermatitis (L24)
The ICD-10 code L24 identifies irritant contact dermatitis, a skin reaction caused by exposure to various irritants such as detergents, oils, solvents, cosmetics, drugs, or body fluids. These codes capture specific irritants to accurately classify and document the type of irritant contact dermatitis encountered.
Each subcategory of L24 defines the source of skin irritation: for example, L24.0 is for dermatitis caused by detergents, while L24.1 covers irritant contact dermatitis caused by oils and greases (including automotive grease). Codes like L24.A1 specify dermatitis due to saliva, and L24.B1 describes dermatitis linked to digestive stomas or fistulas. Synonyms such as “oil contact dermatitis” or “peristomal dermatitis” help connect common terminology with these official codes. Using the ICD-10 code for irritant contact dermatitis ensures precise identification of the irritant agent, aiding in treatment planning and accurate health records.

Instructional Notations
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.
