About L24.A

L24.A is the ICD-10-CM diagnosis code for irritant contact dermatitis due to friction or contact with body fluids. It belongs to category L24 (irritant 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 4 subcodes must be used instead.

Within L24 (irritant contact dermatitis), L24.A is specifically for irritant contact dermatitis due to friction or contact with body fluids. Related codes cover due to detergents (L24.0), due to oils and greases (L24.1), due to solvents (L24.2), due to cosmetics (L24.3), due to drugs in contact with skin (L24.4), due to other chemical products (L24.5), due to food in contact with skin (L24.6), due to plants, except food (L24.7) and 3 more.

To report this condition, pick the subcode that matches the documentation: L24.A0 (unspecified), L24.A1 (saliva), L24.A2 (incontinence) and L24.A9 (fluids).

Don't report L24.A together with the conditions in its Excludes1 note: irritant contact dermatitis related to stoma or fistula (L24.B-).

The conditions in its Excludes2 note aren't part of L24.A, but may be coded alongside it if the patient has both: erythema intertrigo (L30.4).

It was added in FY2022, effective October 1, 2021.
