Anomalies of skull and face bones

This code signifies congenital malformations affecting the bones of the cranium and facial skeleton. These anomalies can range from minor structural variations to severe deformities impacting facial symmetry, cranial shape, and the development of associated structures.

Use this code for documented congenital conditions such as craniosynostosis, plagiocephaly (due to bony anomaly), micrognathia, macrognathia, or other specified congenital deformities of the skull and facial bones. Documentation should clearly indicate a congenital origin and specify the affected bony structure.

• Differentiate from acquired deformities of the skull and face, which would be coded elsewhere.
• Be specific; if a more precise congenital anomaly code exists (e.g., for specific types of craniosynostosis), use that instead.
• Ensure documentation specifies the congenital nature of the anomaly, not just a descriptive term.
