Chronic periodontitis, unspecified

This code signifies a long-standing, uncharacterized inflammatory disease affecting the supporting structures of the teeth, including the gingiva, periodontal ligament, cementum, and alveolar bone. It indicates a persistent infection and inflammation that has led to irreversible destruction of these tissues, without further specification of severity or extent.

Apply this code when the medical record documents chronic periodontitis but lacks specific details regarding its severity (e.g., mild, moderate, severe) or localization (e.g., localized, generalized). It is appropriate when the provider's diagnosis simply states "chronic periodontitis" without further elaboration.

• Avoid using this code if the documentation specifies the severity or extent of the periodontitis; instead, use a more specific code from the K05.3 series.
• Ensure the documentation clearly indicates "chronic" rather than "acute" periodontitis.
• Consider co-reporting with codes for associated conditions like diabetes (E08-E13) if documented as contributing factors.
