ICD-10 Code K11.7 – Disturbances of Salivary Secretion (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K11.7 – Disturbances of salivary secretion
What it is
K11.7 identifies a disturbance in saliva production or flow, such as too little saliva, too much saliva, or abnormal salivary function. Use it when the record describes a salivary secretion problem without a more specific diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings include dry mouth, excessive drooling, or complaints of altered salivation, sometimes with difficulty speaking, swallowing, or maintaining oral comfort.
When to use this code
Use K11.7 when the clinician documents a salivary secretion disturbance and does not name a more specific condition. It is appropriate for symptom-based documentation, such as xerostomia or hypersalivation, when no clearer etiology is recorded. Check documentation if the chart suggests an underlying disease, medication effect, or post-treatment cause.
Do not use for
Do not use this code when the record gives a more specific salivary gland disorder or a separate cause for the symptom. If the issue is documented as a complication or a different oral condition, code that condition instead.
Coding tip
Code the documented salivary problem as written, and look for a more specific diagnosis before defaulting to K11.7.
