Fistula of salivary gland

This code signifies an abnormal, pathological tract or opening involving a salivary gland, allowing saliva to escape to an external surface or another internal structure. This condition can result from trauma, infection, surgery, or obstruction, leading to persistent salivary leakage.

Apply this code when documentation clearly indicates an acquired fistula originating from a salivary gland. This includes cases of post-surgical salivary fistulas, those resulting from injury, or fistulas secondary to inflammatory processes. Ensure the physician's notes specify the presence of a fistula and its connection to a salivary gland.

• Differentiate from congenital salivary gland fistulas, which are coded separately per the Excludes1 note.
• Do not use for salivary gland cysts or other non-fistulous conditions of the salivary glands.
• Look for documentation specifying the cause of the fistula, as an external cause code may be necessary if due to injury.
