About coding chronic sialoadenitis

The ICD-10-CM code for chronic sialoadenitis is K11.23 (Chronic sialoadenitis).

Within K11.2 (sialoadenitis), K11.23 is specifically for chronic sialoadenitis. Related codes cover unspecified (K11.20), acute sialoadenitis (K11.21) and acute recurrent sialoadenitis (K11.22).

Use an additional 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) and 2 more.
