Aggressive periodontitis, localized, slight

This code describes a form of periodontitis characterized by rapid attachment loss and bone destruction, primarily affecting localized areas of the dentition. It is further specified as being in its initial, less severe stage.

Use this code when documentation indicates a diagnosis of aggressive periodontitis that is confined to specific teeth or areas, and the severity is classified as "slight" based on clinical and radiographic findings. Supporting documentation includes periodontal charting, radiographic evidence of bone loss, and a clear diagnosis from a dentist or periodontist.

• Ensure the documentation explicitly states "aggressive periodontitis" and specifies "localized" and "slight" severity.
• Differentiate from chronic periodontitis codes (K05.3-) which have a slower progression and are more common.
• Do not use if the periodontitis is generalized or if the severity is moderate or severe; refer to other codes within the K05.2- subcategory.
