ICD-10 Code L24.B2 – Irritant contact dermatitis related to respiratory stoma or fistula (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L24.B2 – Irritant contact dermatitis related to respiratory stoma or fistula
What it is
This code identifies irritant contact dermatitis caused by exposure around a respiratory stoma or fistula. Use it when skin inflammation is linked to moisture, secretions, adhesives, or other local irritants near the opening.
Clinical signs
Typical findings include localized redness, burning, itching, dryness, scaling, or skin breakdown around the stoma or fistula site. Clinical features vary; refer to documentation.
When to use this code
Use L24.B2 when the provider documents irritant dermatitis specifically related to a respiratory stoma or fistula. It fits cases where the skin reaction is attributed to ongoing local irritation rather than infection or an allergic cause. Check documentation if the note only says “rash” or “irritation.”
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. If the relationship to the stoma or fistula is not stated, check documentation.
Coding tip
Link the dermatitis to the respiratory stoma or fistula only when the provider clearly documents that connection.
