Chronic periodontitis, generalized, moderate

This code signifies a persistent, widespread inflammatory disease affecting the supporting structures of the teeth, characterized by moderate bone loss and attachment loss across most teeth. It indicates a chronic progression of periodontal disease impacting a significant portion of the dentition.

Apply this code when documentation clearly indicates generalized chronic periodontitis with moderate severity. This typically involves clinical findings such as moderate probing depths, moderate clinical attachment loss, and radiographic evidence of moderate alveolar bone loss affecting 30% or more of the teeth.

• Ensure the documentation specifies "generalized" and "moderate" to accurately assign this code.
• Differentiate from localized periodontitis (K05.31-) and other severities (mild K05.321, severe K05.323).
• Look for specific measurements of probing depths, attachment loss, and radiographic bone loss to support the "moderate" classification.
