Mandibular hypoplasia

This code describes an underdeveloped or abnormally small mandible (lower jaw bone). This condition can affect facial symmetry, dental occlusion, and airway patency, ranging from mild to severe.

Use this code when documentation explicitly states mandibular hypoplasia or micrognathia. This diagnosis is often made based on clinical examination, radiographic imaging (e.g., panoramic X-ray, CT scan), or cephalometric analysis.

• Differentiate from other craniofacial anomalies; ensure the documentation specifically points to the mandible.
• Consider co-occurring conditions, such as Pierre Robin sequence, and code them separately if present.
• Review imaging reports and physician notes for precise anatomical descriptions and severity.
