ICD-10 Code K06.2 – Gingival and edentulous alveolar ridge lesions associated with trauma (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K06.2 – Gingival and edentulous alveolar ridge lesions associated with trauma
What it is
K06.2 identifies traumatic lesions of the gingiva or edentulous alveolar ridge. Use it when the record shows injury-related damage to gum tissue or the ridge where teeth are absent.
Clinical signs
Findings may include localized pain, swelling, ulceration, bleeding, or visible tissue injury after biting, denture irritation, or another trauma. Clinical features vary; refer to documentation.
When to use this code
Use K06.2 when the provider documents a traumatic lesion affecting the gingiva or an edentulous alveolar ridge. It fits cases tied to mechanical injury, such as a sharp dental edge, poorly fitting prosthesis, or accidental oral trauma.
Code it only when the lesion is described as trauma-related and not better explained by infection, periodontal disease, or a separate oral condition. Check documentation for laterality, cause, and any associated injury details.
Do not use for
Do not use this code for gingival inflammation, periodontal disease, or mouth ulcers without documented trauma. If the record does not clearly link the lesion to injury, check documentation.
Coding tip
Look for explicit wording such as “traumatic,” “injury,” or “denture-related irritation” before assigning K06.2.
