About K11.2

K11.2 is the ICD-10-CM diagnosis code for sialoadenitis. It belongs to category K11 (diseases of salivary glands), 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 4 subcodes must be used instead.

Within K11 (diseases of salivary glands), K11.2 is specifically for sialoadenitis. Related codes cover atrophy of salivary gland (K11.0), hypertrophy of salivary gland (K11.1), abscess of salivary gland (K11.3), fistula of salivary gland (K11.4), Sialolithiasis (K11.5), mucocele of salivary gland (K11.6), disturbances of salivary secretion (K11.7), other diseases of salivary glands (K11.8) and 1 more.

To report this condition, pick the subcode that matches the documentation: K11.20 (unspecified), K11.21 (sialoadenitis), K11.22 (sialoadenitis) and K11.23 (sialoadenitis).

Don't report K11.2 together with the conditions in its Excludes1 note: epidemic parotitis (B26.-), mumps (B26.-) and uveoparotid fever [Heerfordt] (D86.89).

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.
