ICD-10 Code L24.B0 – Irritant contact dermatitis related to unspecified stoma or fistula (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L24.B0 – Irritant contact dermatitis related to unspecified stoma or fistula
What it is
This code identifies irritant contact dermatitis caused by exposure around an unspecified stoma or fistula. It refers to localized skin inflammation from moisture, effluent, adhesive products, or other irritants.
Clinical signs
Typical findings include redness, burning, itching, scaling, or skin breakdown near the stoma or fistula site. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record documents irritant dermatitis linked to a stoma or fistula, but the exact type is not specified. It fits cases where the provider attributes the skin reaction to leakage, appliance contact, or ongoing irritation. Check documentation if the dermatitis is allergic, infectious, or due to another cause.
Do not use for
Do not use this code for allergic contact dermatitis, pressure injury, or nonspecific skin rash without a documented irritant cause. Check documentation if the site is not a stoma or fistula.
Coding tip
Assign the stoma or fistula dermatitis code only when the provider clearly links the skin condition to irritant exposure.
