Aggressive periodontitis, generalized, moderate

This code signifies a widespread, destructive form of periodontitis characterized by rapid attachment loss and bone destruction affecting most teeth. It typically presents in systemically healthy individuals and progresses quickly if untreated, often leading to tooth mobility and loss.

Apply this code when documentation clearly indicates aggressive periodontitis affecting the majority of dentition, with clinical signs and symptoms consistent with moderate severity. This includes evidence of significant probing depths, clinical attachment loss, and radiographic bone loss that is more advanced than early stages but not yet severe.

• Differentiate from chronic periodontitis based on the rapid progression and typical age of onset, even if generalized.
• Ensure the documentation specifies "generalized" (affecting at least 30% of teeth) and "moderate" severity.
• Avoid using this code if the periodontitis is localized or if the severity is described as mild or severe.
