About coding Glossopathy
The ICD-10-CM code for Glossopathy is K14.9 (Disease of tongue, unspecified).
Within K14, choose K14.9 (Disease of tongue, unspecified) only when documentation doesn't support a more specific option: glossitis (K14.0), Geographic tongue (K14.1), median rhomboid glossitis (K14.2), hypertrophy of tongue papillae (K14.3), atrophy of tongue papillae (K14.4), Plicated tongue (K14.5), Glossodynia (K14.6) and other diseases of tongue (K14.8).
Use an additional code to identify: alcohol abuse and dependence (F10.-), exposure to environmental tobacco smoke (Z77.22), history of tobacco dependence (Z87.891), occupational exposure to environmental tobacco smoke (Z57.31), tobacco dependence (F17.-) and 1 more.
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
