Diseases of tongue (K14) ICD-10-CM
The K14 code range covers diseases of tongue with 10 ICD-10-CM diagnosis codes. 9 of them are billable and valid for claim submission in fiscal year 2027, and the category headers group them but cannot themselves be billed.
Use Additional Code
The “use additional code” indicates that a secondary code could be used to further specify the patient’s condition. This note is not mandatory and is only used if enough information is available to assign an additional code.
- code to identify:
- alcohol abuse and dependence F10
- exposure to environmental tobacco smoke Z77.22
- history of tobacco dependence Z87.891
- occupational exposure to environmental tobacco smoke Z57.31
- tobacco dependence F17
- tobacco use Z72.0
Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

About the K14 Code Range
Tongue diseases belong to the broader group of diseases of the mouth and salivary glands.
The subdivisions separate named tongue conditions from enlargement or shrinking of tongue papillae. They include separate entries for geographic tongue and plicated tongue. K14.3 identifies enlarged tongue papillae, while K14.4 identifies shrinkage. Other tongue diseases and unspecified tongue disease have separate entries.
