Diseases of salivary glands (K11)

The ICD-10 code section K11 is designated for diseases of the salivary glands, which include a variety of conditions affecting these glands responsible for saliva production. This coding group covers disorders such as atrophy, hypertrophy, inflammation, obstruction, and malfunction of salivary glands.

This section features specific codes like K11.0 for atrophy of salivary glands, which may be known as atrophy of the parotid, submandibular, or sublingual glands. Conditions involving enlargement, like hypertrophy (K11.1), include terms such as adenomatoid hyperplasia and hyperplasia of minor salivary glands. The codes for sialoadenitis (inflammation of the salivary gland) range from unspecified (K11.20) to acute, recurrent, and chronic forms (K11.21-K11.23). Other important conditions coded here include salivary gland abscess (K11.3), fistula (K11.4), and sialolithiasis, which involves salivary stones (K11.5). Disorders of secretion, including xerostomia (dry mouth), fall under K11.7. Additional salivary gland diseases like necrotizing sialometaplasia and duct stenosis are covered by K11.8, while K11.9 denotes unspecified salivary gland diseases. These codes help medical coders accurately classify a wide range of salivary gland disorders for clinical and billing purposes, ensuring proper documentation of conditions such as parotitis, ranula, and salivary duct obstruction within the ICD-10 system.

Instructional Notations

Use Additional Code

The “use additional code” indicates that a secondary code could be used to further specify the patient’s condition. This note is not mandatory and is only used if enough information is available to assign an additional code.

  • code to identify:
  • alcohol abuse and dependence F10
  • exposure to environmental tobacco smoke Z77.22
  • exposure to tobacco smoke in the perinatal period P96.81
  • history of tobacco dependence Z87.891
  • occupational exposure to environmental tobacco smoke Z57.31
  • tobacco dependence F17
  • tobacco use Z72.0

Clinical Terms

The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.

Hypohidrosis

Abnormally diminished or absent perspiration. Both generalized and segmented (reduced or absent sweating in circumscribed locations) forms of the disease are usually associated with other underlying conditions.

Mumps

An acute infectious disease caused by RUBULAVIRUS, spread by direct contact, airborne droplet nuclei, fomites contaminated by infectious saliva, and perhaps urine, and usually seen in children under the age of 15, although adults may also be affected. (From Dorland, 28th ed)

Oral Fistula

An abnormal passage within the mouth communicating between two or more anatomical structures.

Parotitis

INFLAMMATION of the PAROTID GLAND.

Ranula

A form of retention cyst of the floor of the mouth, usually due to obstruction of the ducts of the submaxillary or sublingual glands, presenting a slowly enlarging painless deep burrowing mucocele of one side of the mouth. It is also called sublingual cyst and sublingual ptyalocele.

Rubulavirus

A genus of the family PARAMYXOVIRIDAE (subfamily PARAMYXOVIRINAE) where all the species have hemagglutinin and neuraminidase activities but lack a C protein. MUMPS VIRUS is the type species.

Xerostomia

Decreased salivary flow.
