K08.8Other specified disorders of teeth and supporting structures

K08.8 is the ICD-10-CM diagnosis code for other specified disorders of teeth and supporting structures. It belongs to category K08 (other disorders of teeth and supporting structures), 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 3 subcodes must be used instead.

Within K08, choose K08.8 (Other specified disorders of teeth and supporting structures) only when documentation doesn't support a more specific option: Exfoliation of teeth due to systemic causes (K08.0), complete loss of teeth (K08.1), atrophy of edentulous alveolar ridge (K08.2), retained dental root (K08.3), partial loss of teeth (K08.4), unsatisfactory restoration of tooth (K08.5) and disorder of teeth and supporting structures, unspecified (K08.9).

To report this condition, pick the subcode that matches the documentation: K08.81 (trauma), K08.82 (trauma) and K08.89 (structures).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015, and changed in FY2017 (expanded into subcodes).
