Inclusion Terms
- Hypoptyalism
- Ptyalism
- Xerostomia
Type 2 Excludes
- dry mouth NOS R68.2
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

Patient EducationClinical
Salivary Gland Disorders
Your salivary glands are in your mouth. You have three pairs of major salivary glands and hundreds of small (minor) glands. They make saliva (spit) and empty it into your mouth through openings called ducts. Saliva makes your food moist, which helps you chew and swallow. It helps you digest your food.

Questions About K11.7Overview
Is K11.7 (Diseases of salivary glands) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report disturbances of salivary secretion on HIPAA-covered claims from October 1, 2025 through September 30, 2026.
What MS-DRG does K11.7 group to?
When disturbances of salivary secretion is the principal diagnosis on an inpatient stay, it groups to MS-DRG 154, 155, 156, with relative weights from 0.6911 to 1.5635 depending on complications. Higher weights mean higher Medicare reimbursement.
What is the ICD-9 equivalent of K11.7?
Under the General Equivalence Mappings, disturbances of salivary secretion converts to ICD-9-CM 527.7 (salivary secretion dis). The mapping is approximate, so confirm the match fits the documentation.
Footnotes
[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
