ICD-10 Code K14 – Diseases of tongue (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K14 – Diseases of tongue
What it is
K14 identifies diseases affecting the tongue, including inflammatory, structural, or other non-neoplastic disorders. Use it when the record documents a tongue condition but does not specify a more exact code.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include tongue pain, swelling, discoloration, ulceration, coating, or altered taste, depending on the specific disorder.
When to use this code
Use K14 when the clinician documents a tongue disease and no more specific ICD-10 code is available or supported. It also fits nonspecific tongue disorders noted on exam, problem lists, or discharge summaries. If the chart names a distinct diagnosis, code that condition instead.
Do not use for
Do not use K14 for malignant neoplasms, traumatic injuries, or congenital anomalies of the tongue. Check documentation for a more specific diagnosis before assigning this code.
Coding tip
Code the documented tongue condition as specifically as possible; use K14 only when the record is nonspecific or no better code applies.
