Partial loss of teeth due to periodontal diseases, class I

This code signifies the partial absence of natural teeth resulting from the progression of periodontal disease. Specifically, it denotes a Class I classification, indicating a mild to moderate extent of tooth loss directly attributable to the destructive processes of periodontitis. This condition impacts the patient's dentition and oral function.

Use this code when documentation clearly indicates that some, but not all, natural teeth are missing due to a diagnosed periodontal disease, and the tooth loss is categorized as Class I. This typically applies to patients presenting with a history of periodontitis and subsequent tooth extractions or exfoliation directly linked to the disease's severity. Supporting documentation should include dental records, periodontal charting, and clinician notes specifying the etiology of tooth loss.

• Ensure the documentation explicitly links the tooth loss to periodontal disease, not other causes like trauma or caries.
• Verify the "Class I" designation for the extent of tooth loss; other classes exist for more severe partial or complete loss.
• Consider sequencing this code after a more specific code for the underlying periodontal disease (e.g., K05.30-K05.32) if the active disease is also being treated.
