ICD-10 Code K06.020 – Generalized gingival recession, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K06.020 – Generalized gingival recession, unspecified
What it is
K06.020 identifies generalized gingival recession affecting multiple teeth, without a specified cause. The gum margin has receded, exposing more tooth surface or root area.
Clinical signs
Typical findings include visibly receded gums on several teeth, root exposure, and possible tooth sensitivity. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record states generalized gingival recession and does not name a more specific etiology or localized pattern. It fits documentation describing widespread gum recession across the mouth. If the note identifies a different periodontal condition or a localized recession only, choose the more accurate code.
Do not use for
Do not use it for localized gingival recession or for recession clearly linked to another documented condition if a more specific code is available. Check documentation.
Coding tip
Verify that the provider documents both the generalized distribution and the absence of a specified cause before assigning K06.020.
