Chronic periodontitis, generalized, unspecified severity

This diagnosis code signifies a long-standing, widespread inflammatory disease affecting the supporting structures of the teeth, specifically the gingiva, periodontal ligament, and alveolar bone. It indicates a chronic form of periodontitis that is present throughout the mouth, without a specified level of severity.

This code is appropriate when documentation confirms a generalized, chronic periodontal condition but does not specify whether it is mild, moderate, or severe. It is used when the clinician has diagnosed chronic periodontitis affecting multiple quadrants, and the severity is either not assessed or not documented.

• Only use this code when the severity is truly unspecified; otherwise, select a more specific code (e.g., mild, moderate, severe).
• Ensure documentation clearly states "generalized" to differentiate from localized forms of periodontitis.
• This code is often used when initial diagnosis is made, and further assessment for severity is pending or not performed.
