Maxillary hypoplasia

This code describes an underdeveloped or abnormally small maxilla (upper jawbone). This condition can affect facial aesthetics, dental occlusion, and airway function due to insufficient growth of the midface.

Use this code when documentation clearly indicates a diagnosis of maxillary hypoplasia, often identified through clinical examination, dental models, or imaging studies such as cephalometric radiographs or CT scans. It is typically seen in patients with craniofacial anomalies or as an isolated finding.

• Differentiate from other craniofacial anomalies affecting the maxilla; ensure the documentation specifically states "hypoplasia."
• Consider sequencing with codes for associated dental malocclusions (e.g., K07.0-K07.9) or other congenital anomalies if present.
• Avoid using for general facial asymmetry or unspecified jaw developmental issues without explicit documentation of maxillary underdevelopment.
