ICD-10 Code K06.023 – Generalized Gingival Recession, Severe (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K06.023 – Generalized gingival recession, severe
What it is
K06.023 identifies severe recession of the gum tissue affecting multiple teeth across the mouth. The gum margin has moved apically enough to expose more tooth root than in mild or moderate cases.
Clinical signs
You may see widespread root exposure, elongated-looking teeth, and increased sensitivity to touch, cold, or brushing. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record clearly documents generalized gingival recession and describes it as severe. It fits cases involving multiple sites rather than a single localized area. If severity or extent is not stated, check documentation before assigning the code.
Do not use for
Do not use this code for localized recession limited to one tooth or a small area. Do not assign it when the chart only notes gingival inflammation, periodontal disease, or recession without severity or generalized involvement.
Coding tip
Match both qualifiers: generalized distribution and severe severity must be documented.
