About coding salivary gland lesion
The ICD-10-CM code for salivary gland lesion is K11.9 (Disease of salivary gland, unspecified). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on K11.9.
Within K11, choose K11.9 (Disease of salivary gland, unspecified) only when documentation doesn't support a more specific option: atrophy of salivary gland (K11.0), hypertrophy of salivary gland (K11.1), sialoadenitis (K11.2), 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) and 1 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 is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
