L24 — Irritant contact dermatitis

Not billable

Is L24 billable?

No — L24 is a non-billable header code. L24 groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 19 billable codes beneath L24.

Excludes1 — never code together

The conditions below can never be reported together with L24 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

Excludes2 — not included here

The conditions below are not part of L24, but a patient may have both at the same time. When documentation supports it, L24 and the excluded code may both be reported.

  • allergic contact dermatitis (L23.-)

  • dermatitis of eyelid (H01.1-)
  • diaper dermatitis (L22)
  • eczema of external ear (H60.5-)

  • radiation-related disorders of the skin and subcutaneous tissue (L55-L59)

Excludes2 — not included here — inherited from Chapter 12

What codes fall under L24? (12)

How long has L24 existed?

L24 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.

Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.

Which codes are confused with L24?

ICD-10-CM declares these codes mutually exclusive with L24 — exactly one of each pair can be correct for a given encounter.
