ICD-10 Code K11.2 – Sialoadenitis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K11.2 – Sialoadenitis
What it is
K11.2 identifies inflammation of a salivary gland. You use it when the record documents sialoadenitis, whether acute or chronic, and the affected gland is not coded elsewhere.
Clinical signs
Typical findings include gland swelling, tenderness, and pain, sometimes with fever or difficulty eating. Clinical features vary; refer to documentation for the specific gland involved and whether obstruction or infection is noted.
When to use this code
Use K11.2 when the provider diagnoses sialoadenitis and does not assign a more specific salivary gland code. It fits encounters for documented inflammation of a salivary gland, including cases described as infectious or noninfectious if no other code is specified.
Do not use for
Do not use this code for salivary gland stones, tumors, or dry mouth without inflammation. Check documentation if the note describes a different salivary gland disorder or a more specific etiology.
Coding tip
Confirm the exact gland and cause in the note before coding, because more specific salivary gland diagnoses may apply.
