ICD-10 Code K13.24 – Leukokeratosis nicotina palati (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K13.24 – Leukokeratosis nicotina palati
What it is
K13.24 identifies leukokeratosis nicotina palati, a white, thickened change on the palate linked to tobacco exposure, especially smoking or heat irritation. It describes a clinical finding rather than a separate disease process.
Clinical signs
You may see a diffuse white or grayish palate with a rough, keratotic surface and small red puncta at salivary duct openings. Clinical features vary; refer to documentation.
When to use this code
Use K13.24 when the provider documents leukokeratosis nicotina palati, smoker’s palate, or an equivalent diagnosis affecting the hard palate. Code it when the record clearly links the palatal lesion to tobacco or heat exposure. If the documentation only says “white oral lesion,” check documentation.
Do not use for
Do not use this code for oral candidiasis, leukoplakia of another site, or nonspecific mouth irritation without documented palatal leukokeratosis. If the lesion is not specifically on the palate, check documentation.
Coding tip
Confirm the exact oral site and the provider’s wording before assigning K13.24.
