Other disorders of gingiva and edentulous alveolar ridge (K06) ICD-10-CM
The K06 code range covers other disorders of gingiva and edentulous alveolar ridge with 17 ICD-10-CM diagnosis codes. 13 of them are billable and valid for claim submission in fiscal year 2027, and the category headers group them but cannot themselves be billed.
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.

Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the K06 range.
Gingival Recession
Exposure of the root surface when the edge of the gum (GINGIVA) moves apically away from the crown of the tooth. This is common with advancing age, vigorous tooth brushing, diseases, or tissue loss of the gingiva, the PERIODONTAL LIGAMENT and the supporting bone (ALVEOLAR PROCESS).
About the K06 Code Range
These disorders affect the gums or the ridge where teeth are missing. They include receding or enlarged gums, trauma-related lesions, and horizontal loss of bone in the ridge.
K06.0 separates receding gums into localized and generalized recession. Each branch then distinguishes minimal, moderate, severe, and unspecified severity. K06.1 describes enlarged gums, while K06.2 describes trauma-related lesions of the gums or toothless ridge. K06.3 identifies horizontal bone loss. K06.8 and K06.9 distinguish other specified disorders from unspecified disorders.
