ICD-10 Code K11 – Diseases of salivary glands (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K11 – Diseases of salivary glands
What it is
K11 covers disorders of the salivary glands, including inflammation, obstruction, enlargement, and other non-neoplastic gland diseases. Use it when the record identifies a salivary gland condition but does not specify a more exact code.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include swelling near the jaw or under the tongue, pain with eating, dry mouth, or recurrent gland inflammation.
When to use this code
Use K11 when the provider documents a disease of the salivary gland and no more specific subcategory is available or appropriate. It also fits nonspecific salivary gland disorders that are not clearly infectious, traumatic, or neoplastic. Check documentation if the note names a specific gland or cause.
Do not use for
Do not use K11 for salivary gland tumors, injuries, or conditions that have a separate, more specific ICD-10 code. If the chart points to a different diagnosis category, code that condition instead.
Coding tip
Review the provider’s wording closely and code the most specific salivary gland diagnosis documented.
