What This Code Means

Significant loss of bone in the lower jaw (mandible) that has progressed to a severe level, often resulting from tooth loss or periodontal disease.

Coding Tips

• •This code indicates advanced mandibular bone resorption; document the underlying cause if known (e.g., periodontal disease, tooth loss)
• •Severity level 'severe' distinguishes this from minimal or moderate atrophy codes; ensure clinical documentation supports this severity
