Complete loss of teeth due to periodontal dis, class III

This code signifies the total absence of natural teeth in a patient, specifically attributed to advanced and irreversible periodontal disease. It indicates a severe stage of tooth loss where all dentition has been lost due to the destruction of supporting structures.

Apply this code when documentation clearly states complete edentulism resulting from chronic or aggressive periodontitis. This diagnosis is typically supported by dental records detailing extensive bone loss, multiple extractions due to periodontal disease, and the current state of full anodontia.

• Ensure the documentation explicitly links the complete tooth loss to periodontal disease, not other causes like trauma or caries.
• Do not use this code for partial tooth loss or edentulism due to congenital absence or other non-periodontal etiologies.
• Consider sequencing this code as a primary diagnosis when it is the main reason for the encounter, such as for prosthetic rehabilitation.
