ICD-10 Code K06 – Other disorders of gingiva and edentulous alveolar ridge (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K06 – Other disorders of gingiva and edentulous alveolar ridge
What it is
K06 covers noninflammatory disorders of the gums and the edentulous alveolar ridge. Use it for gingival or ridge conditions not classified elsewhere in ICD-10-CM.
Clinical signs
Clinical features vary; refer to documentation. Findings may include abnormal gingival contour, recession, enlargement, or ridge changes in a toothless area.
When to use this code
Use K06 when the record identifies a gingival or edentulous ridge disorder without a more specific diagnosis. It may fit chronic structural or developmental changes documented by the clinician. If the note names a more specific gingival condition, code that instead.
Do not use for
Do not use K06 for inflammatory periodontal disease, gingivitis, or abscesses with a separate code. If the documentation is unclear or another oral condition is named, check documentation.
Coding tip
Code to the most specific gingival or ridge diagnosis documented, and avoid K06 when the chart supports a more precise ICD-10-CM option.
