    ICD-10-CM Code For Disorders Of Tooth Development And Eruption: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group K00 includes congenital and acquired disorders of tooth development and eruption such as anodontia, hypodontia, supernumerary teeth, and disturbances of tooth formation and eruption. These ICD-10-CM diagnosis codes are used to document clinical scenarios involving developmental tooth anomalies, eruption failures, and associated functional or structural complications affecting the oral cavity. Accurate coding within the ICD-10-CM K00 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

    When to Use

    Use a code from this group when documenting clinical encounters for patients with developmental tooth anomalies, eruption failures, or disorders that directly affect tooth formation and positioning. These codes apply when the primary clinical focus is on the diagnosis of the dental developmental or eruption condition rather than a secondary symptom.

    Typical Clinical Scenarios

    • A parent brings a 7-year-old child to a pediatric dental clinic because the child’s primary incisors failed to erupt on schedule and the dentist notes retained primary teeth with delayed eruption of permanent successors. Radiographs show impacted unerupted permanent incisors and abnormal tooth development, prompting a diagnosis related to eruption disturbances. Typical codes: K00.2, K00.4
    • An adult presents to an oral and maxillofacial surgery clinic after a traffic accident with fractured alveolar bone and luxation of several teeth; follow-up reveals teeth that are ankylosed and failing to erupt properly after trauma, with long-term eruption disturbance affecting occlusion. The tooth development and eruption disorder code is used to document the traumatic complication affecting eruption and development. Typical codes: K00.1, K00.3
    • A patient with a longstanding history of ectodermal dysplasia is seen in multidisciplinary care for congenitally missing teeth and abnormal tooth shape affecting function and prosthetic planning; the visit documents hypodontia and other congenital tooth developmental anomalies to guide dental rehabilitation. Typical codes: K00.0, K00.8
