Other periodontal diseases

This code encompasses various periodontal conditions that do not fit into more specific categories of gingivitis or periodontitis. It represents a range of inflammatory and degenerative processes affecting the supporting structures of the teeth, excluding those with clearly defined etiologies or presentations.

Use this code when documentation indicates a periodontal disease that is not specified as gingivitis, chronic periodontitis, aggressive periodontitis, or other explicitly defined conditions. This includes conditions like desquamative gingivitis, necrotizing ulcerative periodontitis not otherwise specified, or other ill-defined periodontal disorders. Documentation should clearly state a periodontal disease that lacks a more precise ICD-10-CM classification.

• Always seek more specific codes for periodontal disease if documentation allows (e.g., K05.2- for aggressive periodontitis).
• Review the "Excludes2" note carefully; do not use this code for leukoplakia of the gingiva (K13.21).
• Ensure the provider's documentation supports the "other" designation, indicating that a more specific diagnosis was not possible or applicable.
