About coding tooth bud deficiency

The ICD-10-CM code for tooth bud deficiency is K00.0 (Anodontia).

Within K00 (disorders of tooth development and eruption), K00.0 is specifically for Anodontia. Related codes cover Supernumerary teeth (K00.1), abnormalities of size and form of teeth (K00.2), Mottled teeth (K00.3), disturbances in tooth formation (K00.4), hereditary disturbances in tooth structure, not elsewhere classified (K00.5), disturbances in tooth eruption (K00.6), Teething syndrome (K00.7), other disorders of tooth development (K00.8) and 1 more.

Don't report K00.0 together with the conditions in its Excludes1 note: acquired absence of teeth (K08.1-).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

Don't confuse with (Excludes1 for K00.0)

  • acquired absence of teeth (K08.1-)
