About L23.8
L23.8 is the ICD-10-CM diagnosis code for allergic contact dermatitis due to other agents. It belongs to category L23 (allergic contact dermatitis), block L20-L30 (dermatitis and eczema) and chapter 12 (diseases of the skin and subcutaneous tissue). It is a header code, so it can't be reported by itself; one of its 2 subcodes must be used instead.
Within L23, choose L23.8 (due to other agents) only when documentation doesn't support a more specific option: due to metals (L23.0), due to adhesives (L23.1), due to cosmetics (L23.2), due to drugs in contact with skin (L23.3), due to dyes (L23.4), due to other chemical products (L23.5), due to food in contact with the skin (L23.6), due to plants, except food (L23.7) and 1 more.
To report this condition, pick the subcode that matches the documentation: L23.81 (dander) and L23.89 (agents).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
