Acute or Chronic Sialoadenitis
Sialoadenitis is the inflammation, enlargement or infection of the salivary glands. It occurs when the flow of saliva is slowed or stopped and is mainly caused by bacterial infection, such as Staphylococcus aureus. Viruses or other medical conditions, including HIV, influenza, herpes, mumps, tumors, dehydration or malnutrition, and more, also may cause Sialoadenitis. It can be diagnosed by CT, Ultrasonography or MRI. This can be treated with antibiotics, hydration and sialagogues. It is subdivided into acute, chronic and recurrent.
Acute Sialoadenitis: In this there is inflammation of parotid and submandibular glands. Clinical features include painful swelling, redness of skin, edema of cheek, fever, malaise.
The predisposing factors for this are:
Poor oral hygiene
Decreased flow or dehydration
Sialolithiasis
Certain drugs
Chronic Sialoadenitis: This is associated with a previous occurrence of acute inflammation and glandular destruction. The decrease in salivary flow is another reason for this condition. Xerostomia, painful swellings are the symptoms associated with this condition.
Under ICD-10-CM, the code selections are easy to understand:
? Sialoadenitis, unspecified K11.20

? Chronic sialoadenitis K11.23
There is an instructional note under category K11 which states to use an additional code to identify the following:
