L24 is a non-billable header ICD-10-CM code for irritant contact dermatitis. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1: never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

allergy NOS (T78.40)
contact dermatitis NOS (L25.9)
dermatitis NOS (L30.9)

Excludes2: not included here, but may coexist

The excluded condition is not part of this code, but a patient can have both. You may code both.

dermatitis due to substances taken internally (L27.-)
dermatitis of eyelid (H01.1-)
diaper dermatitis (L22)
eczema of external ear (H60.5-)
perioral dermatitis (L71.0)
