Complete loss of teeth due to periodontal diseases, class IV

This code signifies the total absence of all natural teeth in the oral cavity, where the primary etiology is advanced periodontal disease. This condition is classified as Class IV, indicating severe and widespread destruction of the supporting structures of the teeth, ultimately leading to their loss.

Apply this code when a patient presents with complete edentulism directly attributable to chronic and severe periodontitis. Documentation should clearly state the complete loss of teeth and explicitly link this loss to a history or current diagnosis of periodontal disease, often supported by radiographic evidence of extensive bone loss.

• Ensure documentation explicitly states "complete loss" or "edentulous" and clearly links the tooth loss to periodontal disease.
• Distinguish from tooth loss due to caries, trauma, or other non-periodontal causes, which would require different codes.
• This code is for the sequela of periodontal disease, not the active disease itself. If active periodontal disease is also present in remaining teeth (if any), code it separately.
