    ICD-10-CM Code For Other Disorders Of Teeth And Supporting Structures: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group K08 includes disorders of teeth and supporting structures such as tooth loss, anomalies of tooth development, and periodontal and periapical conditions that affect tooth integrity and function. These ICD-10-CM diagnosis codes are used to document clinical scenarios including tooth extractions, congenital tooth abnormalities, and periodontal disease severity or complications that impact treatment planning. Accurate coding within the ICD-10-CM K08 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

    ICD-10-CM K08: Other Disorders Of Teeth And Supporting Structures Overview

    The ICD-10-CM K08 group covers diseases and conditions affecting the teeth and their supporting structures, including loss of teeth, defects of tooth development, and disturbances of the periodontal tissues. These diagnoses target the oral cavity and structures that maintain tooth integrity and function. Accurate coding matters for appropriate claim processing and to reflect the clinical complexity relevant to dental and medical services.

    Typical Clinical Scenarios

    • An adult presents to urgent dental care after a motor vehicle collision with multiple avulsed and fractured teeth and loss of several tooth roots; urgent evaluation and stabilization are performed and radiographs show nonrestorable crowns and missing tooth structures requiring extraction and prosthetic planning, so a code describing acquired absence of teeth or traumatic loss of tooth substance is assigned. Typical codes: K08.1, K08.21.
    • An older patient with long-standing periodontal disease has progressive tooth mobility, migration, and loss of multiple teeth over months despite conservative therapy; they present for preprosthetic assessment and documentation of chronic sequelae of tooth loss and need coding for partial edentulism and residual ridge resorption. Typical codes: K08.3, K08.25.
    • A patient with poorly controlled diabetes develops necrosis and sequestration of alveolar bone after recent extraction and presents with pain, exposed bone, and delayed healing; the clinician documents a complication of dental extractions with retained root fragments and alveolar osteonecrosis requiring treatment, so complication codes from the group are used. Typical codes: K08.49, K08.59.
