ICD-10 Code K06.0 – Gingival recession (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K06.0 – Gingival recession
What it is
Gingival recession means the gum margin has moved apically, exposing more of the tooth surface or root. Use this code when documentation identifies recession of the gingiva as the diagnosis.
Clinical signs
Typical findings include visibly longer teeth, exposed root surfaces, and a receded gum line. Sensitivity or localized plaque retention may be noted; clinical features vary, so refer to documentation.
When to use this code
Use K06.0 when the provider documents gingival recession, gum recession, or receding gums as the condition being treated or assessed. It is appropriate for isolated recession and for recession noted during periodontal evaluation. If the record only describes bleeding gums or generalized periodontal disease, check documentation before assigning this code.
Do not use for
Do not use this code for gingivitis, periodontitis, or other periodontal conditions unless recession is specifically documented. If the chart does not clearly identify recession, check documentation.
Coding tip
Code K06.0 only when the record explicitly states gingival recession, not when it is merely implied by tooth sensitivity or cosmetic concern.
