ICD-10 Code K11.9 – Disease of salivary gland, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K11.9 – Disease of salivary gland, unspecified
What it is
K11.9 identifies a salivary gland disorder when the record does not specify the exact gland or condition. Use it for nonspecific salivary gland disease documented without a clearer diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Commonly noted findings may include salivary gland swelling, pain, dry mouth, or reduced saliva flow, but you should not assume a specific cause.
When to use this code
Use K11.9 when the provider documents a salivary gland disease but does not name a more specific diagnosis. It also fits when the chart only states “salivary gland disorder” or another vague term. If later documentation identifies the exact condition, code that instead.
Do not use for
Do not use K11.9 when the record clearly supports a specific salivary gland diagnosis, such as obstruction, inflammation, or another named disorder. Check documentation if the condition is better described elsewhere.
Coding tip
Query for specificity whenever the salivary gland diagnosis is vague, because a more exact code may be available.
