About coding tongue hypertrophy
The ICD-10-CM code for tongue hypertrophy is K14.8 (Other diseases of tongue). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on K14.8.
Within K14, choose K14.8 (Other diseases of tongue) 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 disease of tongue, unspecified (K14.9).
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.
