Severe atrophy of the mandible

This code signifies a significant and advanced reduction in the size and density of the mandibular bone. This severe atrophy can compromise the structural integrity of the jaw, leading to functional impairments such as difficulty with mastication and speech, and often impacting the feasibility of dental prosthetics.

Apply this code when documentation clearly indicates a severe degree of bone loss in the mandible, often described as extreme or advanced atrophy. This typically occurs in edentulous patients over a prolonged period or as a result of trauma or disease. Supporting documentation should include radiographic findings (e.g., panoramic X-rays, CBCT scans) and clinical assessments confirming the severity.

• Differentiate from moderate or mild atrophy; ensure documentation specifies "severe."
• Consider sequencing with codes for underlying causes of atrophy (e.g., long-term edentulism, osteomyelitis) if applicable.
• Do not confuse with codes for congenital hypoplasia or other developmental anomalies of the mandible.
