ICD-10 Code K05.10 – Chronic Gingivitis, Plaque Induced (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K05.10 – Chronic gingivitis, plaque induced
What it is
K05.10 identifies chronic inflammation of the gingiva caused by dental plaque buildup. Use it when the record specifies plaque-induced gingivitis and does not describe a more advanced periodontal condition.
Clinical signs
Typical findings include red, swollen, and bleeding gums, often with plaque accumulation along the gingival margin. Clinical features vary; refer to documentation.
When to use this code
Use K05.10 when the provider documents chronic gingivitis due to plaque, including routine dental or periodontal assessments. It also fits follow-up visits when the condition remains active and is specifically identified as plaque induced.
Do not use for
Do not use this code for gingival disease linked to another cause or for periodontitis with attachment loss. Check documentation if the note only says “gingivitis” without a chronic, plaque-induced diagnosis.
Coding tip
Look for the exact wording “plaque induced” and “chronic” in the assessment before assigning K05.10.
