Chronic periodontitis, localized, slight

This code signifies a persistent, localized inflammation of the supporting structures of a tooth, characterized by slight bone loss and attachment loss. It indicates a mild form of gum disease affecting specific areas of the dentition rather than being generalized throughout the mouth.

Apply this code when documentation specifies chronic periodontitis that is confined to a few teeth or a specific quadrant, and the severity is described as "slight" or "mild" based on clinical and radiographic findings (e.g., 1-2 mm clinical attachment loss, minimal bone loss). This is typically supported by periodontal charting, radiographic evidence, and a dentist's or periodontist's diagnostic statement.

• Ensure documentation clearly specifies "localized" and "slight" to differentiate from generalized or more severe forms.
• Do not confuse with gingivitis (K05.1-) which involves inflammation without attachment loss, or acute periodontitis (K05.2-).
• Always review the full diagnostic statement for laterality (if applicable, though not specified at this level for periodontitis) and any associated conditions.
