Complete loss of teeth due to trauma, class IV

This code signifies the total absence of all natural teeth in both the maxillary and mandibular arches, directly resulting from a traumatic injury. It specifically denotes a Class IV severity, indicating extensive damage and complete edentulism due to the trauma.

Apply this code when a patient presents with complete anodontia (loss of all teeth) that is explicitly documented as being caused by an external force or injury. Documentation should clearly state the traumatic etiology and confirm the absence of all teeth.

• Ensure documentation explicitly links the complete tooth loss to a traumatic event, not other etiologies like periodontal disease or caries.
• Do not use this code for partial tooth loss or edentulism due to non-traumatic causes; consider codes from K08.10-K08.19 for other etiologies.
• Always sequence an external cause code (V00-Y99) as a secondary diagnosis to further specify the nature and circumstances of the trauma.
