K08.1Complete loss of teeth

K08.1 is the ICD-10-CM diagnosis code for complete loss of teeth. 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 (other disorders of teeth and supporting structures), K08.1 is specifically for complete loss of teeth. Related codes cover Exfoliation of teeth due to systemic causes (K08.0), atrophy of edentulous alveolar ridge (K08.2), retained dental root (K08.3), partial loss of teeth (K08.4), unsatisfactory restoration of tooth (K08.5), other specified disorders of teeth and supporting structures (K08.8) and disorder of teeth and supporting structures, unspecified (K08.9).

To report this condition, pick the subcode that matches the documentation: K08.10 (unspecified cause), K08.11 (due to trauma), K08.12 (due to periodontal diseases), K08.13 (due to caries) and K08.19 (due to other specified cause).

Don't report K08.1 together with the conditions in its Excludes1 note: congenital absence of teeth (K00.0), exfoliation of teeth due to systemic causes (K08.0) and partial loss of teeth (K08.4-).

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