About K14

K14 is the ICD-10-CM diagnosis code for diseases of tongue. It belongs to 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 9 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: K14.0 (glossitis), K14.1 (tongue), K14.2 (glossitis), K14.3 (papillae), K14.4 (papillae), K14.5 (tongue), K14.6 (Glossodynia), K14.8 (tongue) and 1 more.

The conditions in its Excludes2 note aren't part of K14, but may be coded alongside it if the patient has both: erythroplakia (K13.29), focal epithelial hyperplasia (K13.29), leukoedema of tongue (K13.29), leukoplakia of tongue (K13.21) and 3 more.

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 has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
