About K08
K08 is the ICD-10-CM diagnosis code for other disorders of teeth and supporting structures. 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 8 subcodes must be used instead.
To report this condition, pick the subcode that matches the documentation: K08.0 (causes), K08.1 (teeth), K08.2 (ridge), K08.3 (root), K08.4 (teeth), K08.5 (tooth), K08.8 (structures) and K08.9 (unspecified).
The conditions in its Excludes2 note aren't part of K08, but may be coded alongside it if the patient has both: dentofacial anomalies [including malocclusion] (M26.-) and disorders of jaw (M27.-).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
