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 2026, 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.
Alveolar Bone Loss
Resorption or wasting of the tooth-supporting bone (ALVEOLAR PROCESS) in the MAXILLA or MANDIBLE.
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
ICD-10 code section K06 covers a range of other disorders of the gingiva and the edentulous alveolar ridge, including various types of gingival recession, enlargement, trauma-related lesions, and alveolar bone loss. These codes help specify conditions beyond common gum diseases, providing detailed classifications for treatment and documentation.
This section includes codes for localized and generalized gingival recession (K06.0 series), addressing the loss of gum tissue which may be described by terms like "gingivitis artefacta" or "interproximal gingival recession." Gingival enlargement (K06.1) covers conditions also known by names such as "hereditary gingival fibromatosis" or drug-induced gum overgrowth. Trauma-related lesions affecting gums and edentulous ridges are captured under K06.2, useful for conditions like avulsion of attached gingiva. Bone loss in the alveolar ridge is described by K06.3, including horizontal alveolar bone loss surrounding implants. Other specified disorders (K06.8) encompass a variety of changes such as gingival clefts, pigmentation, or pyogenic granulomas, while K06.9 is used for unspecified gingival or alveolar disorders including acute and chronic conditions attributed to infections, systemic diseases, or allergies. These codes precisely document unique gum-related diseases in dental and medical records.
Questions About This Page
How many billable codes are in the K06 range?
Of the 17 codes in this range, 13 are billable and valid for claim submission from October 1, 2025 through September 30, 2026. Category header codes group them but cannot be reported on claims.
What does the K06 range classify?
The range classifies other disorders of gingiva and edentulous alveolar ridge. Each code links to its own reference page with billing status, MS-DRG grouping, coding notes, and clinical information.
