L24.A: Irritant contact dermatitis due to friction or contact with body fluids

Non-billable headerICD-10-CM

L24.A is a non-billable header ICD-10-CM code for irritant contact dermatitis due to friction or contact with body fluids. 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.

  • irritant contact dermatitis related to stoma or fistula (L24.B-)

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.

  • erythema intertrigo (L30.4)

Excludes1 inherited from the categories above L24.A

A category’s note binds every code beneath it.
