ICD-10-CM Code K09.0
Developmental odontogenic cysts
Billable Code
Billable codes are sufficient justification for admission to an acute care hospital when used a principal diagnosis.K09.0 is a billable ICD code used to specify a diagnosis of developmental odontogenic cysts. A 'billable code' is detailed enough to be used to specify a medical diagnosis.
The ICD code K090 is used to code Dentigerous cyst
A dentigerous cyst or follicular cyst is an odontogenic cyst - thought to be of developmental origin - associated with the crown of an unerupted (or partially erupted) tooth. The cyst cavity is lined by epithelial cells derived from the reduced enamel epithelium of the tooth forming organ. Regarding its pathogenesis, it has been suggested that the pressure exerted by an erupting tooth on the follicle may obstruct venous flow inducing accumulation of exudate between the reduced enamel epithelium and the tooth crown.

Code Type-2 Excludes:
Type-2 Excludes
Type-2 Excludes means the excluded conditions are different, although they may appear similar. A patient may have both conditions, but one does not include the other. Excludes 2 means "not coded here." - Keratocysts (D16.4, D16.5) - instead, use code D16.4
- Odontogenic keratocystic tumors (D16.4, D16.5) - instead, use code D16.4

Equivalent ICD-9 Code GENERAL EQUIVALENCE MAPPINGS (GEM)
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 526.0 was previously used, K09.0 is the appropriate modern ICD10 code.
