Periodontosis

This code represents a non-inflammatory degenerative condition affecting the periodontium, specifically the supporting structures of the teeth. It involves a progressive breakdown of the periodontal ligament, alveolar bone, and cementum, leading to tooth mobility and eventual tooth loss. Unlike periodontitis, periodontosis is not primarily driven by bacterial infection.

Use this code when documentation explicitly states a diagnosis of "periodontosis" or describes a non-inflammatory, degenerative disease of the periodontium. This diagnosis is less common than periodontitis and requires specific clinical findings to differentiate. Supporting documentation would include clinical notes detailing the absence of significant inflammation, but presence of bone loss and tooth mobility.

• Differentiate carefully from periodontitis (K05.3-), which is an inflammatory condition.
• Ensure the documentation clearly specifies "periodontosis" to avoid miscoding.
• This diagnosis is rare; confirm with the provider if there is any ambiguity in the clinical notes.
