ICD-10 Code K11.8 – Other diseases of salivary glands (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K11.8 – Other diseases of salivary glands
What it is
K11.8 identifies salivary gland disorders that do not fit a more specific ICD-10-CM code. Use it for documented gland disease when the record names a salivary gland condition but gives no narrower diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Commonly, records may note gland swelling, pain, dry mouth, or recurrent inflammation, but you should code only what is actually documented.
When to use this code
Use K11.8 when the clinician documents an unspecified or other salivary gland disorder and no more specific code applies. It is appropriate for conditions such as nonclassified salivary gland disease, provided the note supports a gland-based diagnosis. If the chart names a more specific disorder, code that instead.
Do not use for
Do not use this code when the record supports a specific salivary gland diagnosis with its own code. Also avoid it for symptoms alone, such as isolated dry mouth or swelling, unless the provider diagnoses a salivary gland disorder.
Coding tip
Check the provider’s exact wording first; if the diagnosis is nonspecific, K11.8 may be appropriate, but a more specific salivary gland code takes priority.
