ICD-10 Code K14.3 – Hypertrophy of tongue papillae (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K14.3 – Hypertrophy of tongue papillae
What it is
K14.3 identifies enlarged tongue papillae, meaning the small surface projections on the tongue are visibly overgrown. It is a descriptive oral finding, not a cause.
Clinical signs
You may see prominent, enlarged papillae on the tongue surface, sometimes with a rough or coated appearance. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents hypertrophy of tongue papillae as the diagnosed oral condition. It fits cases where the finding is the reason for evaluation or is recorded as a distinct abnormality. Check documentation if the enlarged papillae are part of another tongue disorder.
Do not use for
Do not use K14.3 for generalized tongue lesions, ulceration, or discoloration without papillary hypertrophy. Do not assign it when the note only describes coating or irritation and does not confirm enlarged papillae.
Coding tip
Code K14.3 only when the provider clearly documents hypertrophy of tongue papillae, not when the finding is implied or uncertain.
