ICD-10 Code K05.11 – Chronic gingivitis, non-plaque induced (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K05.11 – Chronic gingivitis, non-plaque induced
What it is
K05.11 identifies long-standing inflammation of the gums that is not caused by dental plaque. Use it when the record clearly states chronic gingivitis with a non-plaque cause.
Clinical signs
Typical findings include persistent gingival redness, swelling, and bleeding on examination. Clinical features vary; refer to documentation for the specific non-plaque cause.
When to use this code
Use this code when the clinician documents chronic gingivitis and specifies that plaque is not the cause. It may fit cases linked to another documented factor, such as a systemic condition or local irritant. Check documentation if the cause is unclear.
Do not use for
Do not use this code for plaque-induced gingivitis or for gingival inflammation without a chronic, non-plaque diagnosis. If the record does not specify the cause, check documentation.
Coding tip
Code the documented etiology when available, and do not assume non-plaque disease from symptoms alone.
