ICD-10-CM Code K00.2
Abnormalities of size and form of teeth

Billable Code
Billable codes are sufficient justification for admission to an acute care hospital when used a principal diagnosis.
| ICD-10 from 2011 - 2016

K00.2 is a billable ICD code used to specify a diagnosis of abnormalities of size and form of teeth. A 'billable code' is detailed enough to be used to specify a medical diagnosis.

The ICD code K002 is used to code Tooth fusion

The phenomenon of tooth fusion arises through union of two normally separated tooth germs, and depending upon the stage of development of the teeth at the time of union, it may be either complete or incomplete. On some occasions, two independent pulp chambers and root canals can be seen. However, fusion can also be the union of a normal tooth bud to a supernumerary tooth germ. In these cases, the number of teeth is fewer if the anomalous tooth is counted as one tooth. In geminated teeth, division is usually incomplete and results in a large tooth crown that has a single root and a single canal. Both gemination and fusion are prevalent in primary dentition, with incisors being more affected.

Inclusion Terms are a list of concepts for which a specific code is used. The list of Inclusion Terms is useful for determining the correct code in some cases, but the list is not necessarily exhaustive.
Concrescence of teeth
Fusion of teeth
Gemination of teeth

Dens in dente
Dens invaginatus
Enamel pearls

Code Type-1 Excludes:
Type-1 Excludes
Type-1 Excludes mean the conditions excluded are mutually exclusive and should never be coded together. Excludes 1 means "do not code here."
Abnormalities of teeth due to congenital syphilis - instead, use code A50.5
Tuberculum Carabelli, which is regarded as a normal variation and should not be coded

Abnormalities of size and form of teeth (exact match)

This is the official exact match mapping between ICD9 and ICD10, as provided by the General Equivalency mapping crosswalk. This means that in all cases where the ICD9 code 520.2 was previously used, K00.2 is the appropriate modern ICD10 code.
