About K06

K06 is the ICD-10-CM diagnosis code for other disorders of gingiva and edentulous alveolar ridge. 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 6 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: K06.0 (recession), K06.1 (enlargement), K06.2 (trauma), K06.3 (loss), K06.8 (ridge) and K06.9 (unspecified).

The conditions in its Excludes2 note aren't part of K06, but may be coded alongside it if the patient has both: acute gingivitis (K05.0), atrophy of edentulous alveolar ridge (K08.2), chronic gingivitis (K05.1) and gingivitis NOS (K05.1).

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