About K11

K11 is the ICD-10-CM diagnosis code for diseases of salivary glands. It belongs to block K00-K14 (diseases of oral cavity and salivary glands) and chapter 11 (diseases of the digestive system). It is a header code, so it can't be reported by itself; one of its 10 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: K11.0 (gland), K11.1 (gland), K11.2 (sialoadenitis), K11.3 (gland), K11.4 (gland), K11.5 (Sialolithiasis), K11.6 (gland), K11.7 (secretion) and 2 more.

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.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
