Acute sialoadenitis

This code represents an acute inflammatory condition affecting a salivary gland, typically characterized by sudden onset of pain, swelling, and tenderness in the affected gland. It is often caused by bacterial or viral infection, or obstruction of the salivary duct.

Use this code when documentation clearly indicates a new, acute episode of inflammation of a salivary gland. This diagnosis is supported by findings such as unilateral or bilateral salivary gland swelling, erythema, tenderness, and sometimes purulent discharge from the duct.

• Ensure the documentation specifies "acute" and not "acute recurrent" to differentiate from the Excludes1 code.
• Look for the specific salivary gland affected (e.g., parotid, submandibular) if further specificity is available, though this code does not require it.
• Do not use this code for chronic or recurrent inflammation of the salivary glands.
