Inclusion Terms
- Benign lymphoepithelial lesion of salivary gland
- Mikulicz' disease
- Necrotizing sialometaplasia
- Sialectasia
- Stenosis of salivary duct
- Stricture of salivary duct
Type 1 Excludes
- Sjögren syndrome M35.0
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 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Clinical ClassificationClinical
AHRQ’s CCSR groups this code into broader clinical categories.
Clinical InformationClinical
Necrotizing Sialometaplasia
a reactive and self-limiting inflammation of the salivary glands that results in degeneration and necrosis of salivary acini and ductal squamous metaplasia. it usually affects the minor salivary glands in the posterolateral hard palate. it is probably caused by trauma and hypoxia.
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 K11.8Overview
Is K11.8 (Diseases of salivary glands) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report other diseases of salivary glands on HIPAA-covered claims from October 1, 2025 through September 30, 2026.
What MS-DRG does K11.8 group to?
When other diseases of salivary glands 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 K11.8?
Under the General Equivalence Mappings, other diseases of salivary glands converts to ICD-9-CM 527.8 (salivary gland dis NEC). 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.
