ICD-10 Code K11.22 – Acute recurrent sialoadenitis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K11.22 – Acute recurrent sialoadenitis
What it is
K11.22 identifies repeated episodes of acute inflammation of a salivary gland. Use it when the record shows a recurrent pattern rather than a single isolated episode.
Clinical signs
Typical findings include painful gland swelling, tenderness, and symptoms that flare more than once. Clinical features vary; refer to documentation for the involved gland and recurrence pattern.
When to use this code
Use this code when the provider documents acute recurrent sialoadenitis, recurrent salivary gland inflammation, or repeated acute flares of the same condition. It is appropriate when the note clearly distinguishes recurrence from a one-time acute infection.
Do not use for
Do not use it for chronic sialadenitis without acute recurrence, or for nonspecific salivary gland swelling without a documented diagnosis. Check documentation if the chart only says “sialadenitis” or “salivary gland disorder.”
Coding tip
Confirm the word “recurrent” is documented; without it, K11.22 may not be supported.
