ICD-10 Code K06.1 – Gingival Enlargement (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K06.1 – Gingival enlargement
What it is
K06.1 identifies abnormal overgrowth or thickening of the gum tissue. Use it when the chart documents enlarged gingiva, gingival hyperplasia, or gingival overgrowth.
Clinical signs
Typical findings include visibly swollen, bulky, or overgrown gums that may partially cover teeth. Clinical features vary; refer to documentation for the cause and extent.
When to use this code
Use K06.1 when the provider documents gingival enlargement as the diagnosis, whether localized or generalized. It may appear in dental or medical records as a primary finding or as part of another condition. Code it only when the enlargement itself is clearly documented.
Do not use for
Do not use this code for simple gingival inflammation without enlargement. Check documentation if the note describes periodontal disease, abscess, or another gum disorder instead.
Coding tip
Confirm that the record specifically states gingival enlargement, not just gum swelling, before assigning K06.1.
