ICD-10 Code L24.B1 – Irritant contact dermatitis related to digestive stoma or fistula (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L24.B1 – Irritant contact dermatitis related to digestive stoma or fistula
What it is
This code identifies irritant contact dermatitis caused by leakage or exposure around a digestive stoma or fistula. It describes localized skin inflammation from repeated contact with digestive fluids, not an allergic reaction.
Clinical signs
Look for redness, burning, soreness, itching, or skin breakdown around the stoma or fistula site. Clinical features vary; refer to documentation for the exact extent and cause.
When to use this code
Use this code when the record clearly states irritant dermatitis related to a digestive stoma or fistula, such as peristomal skin irritation from leakage. It may also fit when the provider documents excoriation or dermatitis from ostomy output. Check documentation if the cause is not specified.
Do not use for
Do not use this code for allergic contact dermatitis, infection, pressure injury, or unspecified skin irritation without a documented irritant cause. Do not guess the relationship to the stoma or fistula.
Coding tip
Code the dermatitis only when the documentation links it to the digestive stoma or fistula; otherwise, choose the more specific documented skin condition.
