ICD-10 Code K11.3 – Abscess of salivary gland (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K11.3 – Abscess of salivary gland
What it is
K11.3 identifies a localized collection of pus in a salivary gland. Use it when documentation clearly states a salivary gland abscess, not just swelling or infection.
Clinical signs
Typical findings include painful gland enlargement, tenderness, and sometimes redness or fever. Clinical features vary; refer to documentation.
When to use this code
Use K11.3 when the provider documents an abscess involving a salivary gland, such as the parotid or submandibular gland. It is appropriate when the record supports a true abscess rather than nonspecific sialadenitis or obstruction. Check documentation if the note only says “infection” or “swelling.”
Do not use for
Do not use this code for salivary gland swelling, stones, or inflammation without abscess. Check documentation if the condition is described as another salivary gland disorder.
Coding tip
Assign K11.3 only when the abscess is explicitly documented; if the site is unclear, query the provider.
