Maxillary asymmetry

This diagnosis code signifies an uneven development or disproportion in the size or position of the maxilla (upper jaw bone). It indicates a structural imbalance of the upper jaw, which can affect facial symmetry, occlusion, and overall craniofacial aesthetics.

Apply this code when documentation explicitly states maxillary asymmetry, often observed during orthodontic or oral surgery evaluations. It is appropriate for conditions where one side of the maxilla is noticeably different in size, shape, or position compared to the other, impacting the patient's bite or facial appearance. Supporting documentation includes clinical examination findings, cephalometric analysis, and imaging reports.

• Ensure the documentation clearly specifies maxillary asymmetry, not mandibular or generalized facial asymmetry.
• Do not confuse with codes for other dentofacial anomalies unless maxillary asymmetry is specifically documented.
• Consider sequencing this code with other codes describing associated malocclusions or dentofacial deformities if present.
