Inclusion Terms
- Dentia praecox
- Natal tooth
- Neonatal tooth
- Premature eruption of tooth
- Premature shedding of primary deciduous tooth
- Prenatal teeth
- Retained persistent primary tooth
Type 2 Excludes
- embedded and impacted teeth K01
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

Clinical InformationClinical
Steatocystoma Multiplex
a disorder characterized by multiple, wide spread cutaneous cysts that often become inflamed and rupture. it is caused by the same mutations in the gene coding for krt-17 that are causative mutations for pachyonychia congenita, type 2. natal teeth involvement is sometimes associated with steatocystoma multiplex.Natal Teeth
predeciduous teeth present at birth. they may be well formed and normal or may represent hornified epithelial structures without roots. they are found on the gingivae over the crest of the ridge and arise from accessory buds of the dental lamina ahead of the deciduous buds or from buds of the accessory dental lamina. (from jablonski, dictionary of dentistry, 1992)Tooth Loss
the failure to retain teeth as a result of disease or injury.Tooth Loss
one or more teeth lost/dislodged from the mouth.

Questions About K00.6Overview
Is K00.6 (Disorders of tooth development and eruption) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report disturbances in tooth eruption on HIPAA-covered claims from October 1, 2025 through September 30, 2026.
What MS-DRG does K00.6 group to?
When disturbances in tooth eruption is the principal diagnosis on an inpatient stay, it groups to MS-DRG 157, 158, 159, with relative weights from 0.7085 to 1.7168 depending on complications. Higher weights mean higher Medicare reimbursement.
What is the ICD-9 equivalent of K00.6?
Under the General Equivalence Mappings, disturbances in tooth eruption converts to ICD-9-CM 520.6 (tooth eruption disturb). The mapping is approximate, so confirm the match fits the documentation.
Footnotes
[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
