K08.10Complete loss of teeth, unspecified cause

K08.10 is the ICD-10-CM diagnosis code for complete loss of teeth, unspecified cause. 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 5 subcodes must be used instead.

Within K08.1, choose K08.10 (unspecified cause) only when documentation doesn't support a more specific option: due to trauma (K08.11), due to periodontal diseases (K08.12), due to caries (K08.13) and due to other specified cause (K08.19).

To report this condition, pick the subcode that matches the documentation: K08.101 (class I), K08.102 (class II), K08.103 (class III), K08.104 (class IV) and K08.109 (unspecified class).

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