ICD-10 Code K05.01 – Acute gingivitis, non-plaque induced (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K05.01 – Acute gingivitis, non-plaque induced
What it is
K05.01 identifies an acute inflammation of the gingiva that is not caused by dental plaque. Use it for a short-term gum inflammation when the record supports a non-plaque origin.
Clinical signs
Typical findings include red, swollen, tender gums and possible bleeding on contact. Clinical features vary; refer to documentation for the stated cause and whether the process is acute.
When to use this code
Use this code when the clinician documents acute gingivitis and specifically notes a non-plaque cause, such as a local irritant, medication effect, or another stated etiology. It also fits when the diagnosis is clearly recorded without plaque-related disease. Check documentation if the cause is unclear.
Do not use for
Do not use K05.01 for plaque-induced gingivitis or for chronic gingival disease. If the record does not support an acute, non-plaque process, choose the documented condition instead.
Coding tip
Confirm both “acute” and “non-plaque induced” in the note before assigning K05.01.
