Within K13.2 (leukoplakia and other disturbances of oral epithelium, including tongue), K13.24 is specifically for Leukokeratosis nicotina palati. Related codes cover leukoplakia of oral mucosa, including tongue (K13.21), minimal keratinized residual ridge mucosa (K13.22), excessive keratinized residual ridge mucosa (K13.23) and other disturbances of oral epithelium, including tongue (K13.29).
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.
