Partial loss of teeth due to periodontal diseases, class IV

This code signifies a significant reduction in the number of natural teeth within a patient's oral cavity, specifically attributed to the destructive effects of periodontal disease. The "Class IV" designation indicates a severe level of tooth loss, often characterized by extensive bone loss and compromised dentition, impacting mastication and oral function.

Apply this code when documentation clearly states that a patient presents with partial edentulism directly resulting from advanced periodontal disease. This diagnosis is appropriate when the clinician has assessed the extent of tooth loss and determined it meets the criteria for Class IV, indicating a severe and widespread impact of periodontitis on tooth retention.

• Ensure documentation explicitly links the partial tooth loss to periodontal disease and specifies the "Class IV" severity.
• Differentiate from tooth loss due to other etiologies, such as trauma or caries, which would require different codes.
• Consider sequencing this code with a more specific code for the underlying periodontal disease if still active and being treated.
