ICD-10 Code K06.9 – Disorder of gingiva and edentulous alveolar ridge, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K06.9 – Disorder of gingiva and edentulous alveolar ridge, unspecified
What it is
K06.9 identifies an unspecified disorder affecting the gums or the edentulous alveolar ridge. Use it when the record confirms a gingival or ridge condition but does not name a more specific diagnosis.
Clinical signs
Findings may include gum irritation, swelling, recession, or other nonspecific changes around the alveolar ridge. Clinical features vary; refer to documentation.
When to use this code
Use this code when the clinician documents a disorder of the gingiva or edentulous ridge without further detail. It also fits when the note is too nonspecific to support a more exact K06 code. Check documentation if the condition is linked to infection, trauma, or a different oral diagnosis.
Do not use for
Do not use K06.9 when the chart specifies a distinct gingival diagnosis, such as a defined inflammatory or structural disorder. Do not assign it for normal postoperative healing or unrelated dental complaints.
Coding tip
Choose the most specific K06 code available; use K06.9 only when the documentation leaves the gingival or ridge disorder unspecified.
