ICD-10 Code L24.A2 – Irritant contact dermatitis due to fecal, urinary or dual incontinence (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L24.A2 – Irritant contact dermatitis due to fecal, urinary or dual incontinence
What it is
This code identifies irritant contact dermatitis caused by prolonged exposure to feces, urine, or both. It is used when skin breakdown is due to incontinence-related moisture and irritation, not allergy.
Clinical signs
Typical findings include red, inflamed, tender, or macerated skin in the perineal, buttock, or groin area. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents dermatitis specifically linked to fecal, urinary, or dual incontinence. It fits cases where skin irritation is attributed to ongoing exposure to urine or stool. Code it only when the record supports an irritant dermatitis diagnosis, not simple incontinence alone.
Do not use for
Do not use this code for allergic contact dermatitis or for pressure injuries. Do not assign it when the chart only mentions incontinence without dermatitis; check documentation.
Coding tip
Look for wording that ties the rash or skin injury directly to incontinence before assigning L24.A2.
