Unspecified contact dermatitis (L25)
ICD-10 code L25 covers unspecified contact dermatitis, a skin inflammation caused by direct contact with various substances. This category helps healthcare providers specify the cause of contact dermatitis when it is not clearly identified, with more detailed subcodes addressing specific triggers like cosmetics, drugs, dyes, chemicals, food, and plants.
The ICD-10 code for unspecified contact dermatitis includes several subtypes, each relating to different irritants or allergens. For example, L25.0 is used for contact dermatitis caused by cosmetics, also known as perfume contact dermatitis. L25.1 covers cases due to drugs or chemicals like phenol and iodine, often referred to as oil or lanolin contact dermatitis. Colorings and dyes are classified under L25.2, sometimes linked to tattoo-related inflammation. Other chemical products, such as insecticides, detergents, and latex, fall under L25.3. Food-related skin reactions use L25.4, while plant-based allergic reactions, including poison ivy and sumac exposure, are coded as L25.5. The code L25.8 captures various other agents like fiberglass or jewelry, and L25.9 applies when the cause remains unspecified. Knowing these specific codes ensures precise documentation for different contact dermatitis causes.

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.
- allergic contact dermatitis L23
- allergy NOS T78.40
- dermatitis NOS L30.9
- irritant contact dermatitis L24
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.
