ICD-10 Code K06.021 – Generalized gingival recession, minimal (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K06.021 – Generalized gingival recession, minimal
What it is
K06.021 identifies minimal recession of the gums affecting multiple teeth throughout the mouth. It means the gingival margin has moved apically, exposing more tooth surface than normal.
Clinical signs
Clinical features vary; refer to documentation. Typical findings include visible root exposure, elongated tooth appearance, and reduced gum coverage at several sites rather than one isolated area.
When to use this code
Use this code when the record specifically documents generalized gingival recession and identifies it as minimal. It is appropriate for periodontal assessments, dental examinations, or problem lists when the provider notes recession across the dentition.
If the chart does not state the extent or severity, check documentation before coding. Do not infer generalized involvement from a single affected tooth or from nonspecific gum concerns.
Do not use for
Do not use this code for localized recession limited to one area, or when the record only says gingival recession without severity. Check documentation for a more specific code or confirm the diagnosis.
Coding tip
Verify both distribution and severity; “generalized” and “minimal” must be documented to support K06.021.
