ICD-10 Code L23.2 – Allergic contact dermatitis due to cosmetics (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L23.2 – Allergic contact dermatitis due to cosmetics
What it is
L23.2 identifies allergic contact dermatitis caused by cosmetic products. Use it when a delayed skin hypersensitivity reaction is linked to makeup, lotions, perfumes, hair products, or similar personal care items.
Clinical signs
Typical findings include itchy, red, inflamed skin at sites exposed to the cosmetic. Clinical features vary; refer to documentation for rash distribution, swelling, vesicles, or scaling consistent with contact dermatitis.
When to use this code
Use this code when the provider documents allergic contact dermatitis and names cosmetics as the cause. It fits cases where the reaction follows use of a specific product or product class.
Choose it only when the record supports an allergic mechanism, not simple irritation. If the exact cosmetic trigger is documented, capture it clearly in the note.
Do not use for
Do not use L23.2 for irritant contact dermatitis or unspecified dermatitis. Check documentation if the rash is due to another allergen, such as metals, plants, or medications.
Coding tip
Link the diagnosis to the documented cosmetic trigger; if the cause is unclear, code the dermatitis diagnosis the provider actually states.
