Maxillary hyperplasia

This code describes an overgrowth or enlargement of the upper jawbone (maxilla). This condition can lead to facial asymmetry, malocclusion, and functional issues such as difficulty with chewing or speech. It is a developmental anomaly characterized by excessive bone formation in the maxilla.

Use this code when documentation clearly indicates an abnormal increase in the size of the maxilla. This diagnosis is typically made based on clinical examination, dental imaging (e.g., panoramic radiographs, CT scans), and cephalometric analysis. It is appropriate for cases where the hyperplasia is the primary diagnosis or a significant contributing factor to the patient's condition.

• Differentiate from maxillary hypoplasia (underdevelopment), which is a distinct condition.
• Ensure documentation specifies "hyperplasia" of the maxilla, not just general jaw enlargement.
• Consider additional codes for associated malocclusion (e.g., K07.3- series) or other dental anomalies if present and documented.
