Partial loss of teeth due to periodontal diseases, class II

This code signifies a partial edentulism resulting from the destructive effects of periodontal disease, specifically classified as Class II. This means that some teeth are missing due to the breakdown of supporting structures, and the remaining teeth are still present in the arch, but not in ideal occlusion or distribution.

Apply this code when a patient presents with missing teeth directly attributed to chronic or aggressive periodontal disease, and the extent of tooth loss fits the Class II classification. Documentation should clearly state the etiology of tooth loss as periodontal disease and specify the partial nature of the edentulism.

• Ensure documentation explicitly links tooth loss to periodontal disease, not trauma or caries.
• Distinguish from complete edentulism (K08.41-) or partial edentulism due to other causes (K08.43-).
• Consider sequencing this code after a more specific periodontal disease code (e.g., K05.3-) if the active disease is also being treated.
