ICD-10 Code K14.8 – Other diseases of tongue (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K14.8 – Other diseases of tongue
What it is
K14.8 is used for tongue disorders that do not fit a more specific ICD-10 category. It covers other documented diseases of the tongue when the record does not name a different code.
Clinical signs
Clinical features vary; refer to documentation. Records may describe tongue pain, swelling, discoloration, ulceration, coating, or structural abnormality, but the exact finding must be supported in the note.
When to use this code
Use K14.8 when the clinician documents a tongue disease and no more specific diagnosis is available. It is appropriate for nonspecific or unusual tongue conditions that are clearly identified in the chart. If the note names a distinct tongue disorder, code that condition instead.
Do not use for
Do not use this code for normal tongue findings, symptoms without a diagnosis, or conditions better classified elsewhere. Check documentation if the record points to a specific oral, infectious, neurologic, or neoplastic cause.
Coding tip
Look for the exact tongue diagnosis in the assessment before assigning K14.8.
