About the K00–K14 Code Range
ICD-10 codes K00-K14 cover a comprehensive range of diseases affecting the oral cavity and salivary glands. These codes describe conditions from developmental tooth disorders to inflammatory diseases of gums and salivary glands, as well as lesions of the oral mucosa and tongue.
This range begins with K00, detailing abnormalities in tooth development such as anodontia (absence of teeth) and supernumerary teeth (extra teeth). It also includes disorders of tooth size, form, and eruption. Codes like K01 focus on problems related to embedded or impacted teeth. K02 addresses dental caries, specifying whether decay is on the pits, fissures, smooth surfaces, or roots. Hard tissue diseases of teeth, including attrition, abrasion, erosion, and resorption, are captured in K03. The ICD-10 codes K04 cover pulp and periapical tissue diseases, including pulpitis and abscesses. Gingivitis and periodontal diseases, both acute and chronic, fall under K05, while K06 includes gingival recession and enlargement. Tooth loss and defects in supporting structures appear throughout K08. Various cysts in the oral region are in K09. Salivary gland conditions such as sialoadenitis, mucocele, and sialolithiasis are grouped in K11. The K12 codes detail stomatitis and related inflammatory lesions, and finally, K13 and K14 focus on other oral mucosal diseases and tongue disorders respectively.
Synonyms such as recurrent aphthous ulcers (K12.0), periodontitis (K05), dental caries (K02), mucocele (K11.6), and glossitis (K14.0) help clarify coding choices by linking common clinical terms to official ICD-10 codes. This detailed classification aids accurate diagnosis coding, reflecting the wide spectrum of oral health issues from developmental anomalies to infectious and inflammatory diseases affecting teeth, gums, salivary glands, and oral tissues.

What conditions does K00-K14 cover?
The range covers diseases of oral cavity and salivary glands. The code ranges listed above break it into groups of related conditions, and each one links to its own page with the full code list.
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.
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

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.
