Final answer:
Bilateral maxilla or mandible fractures can be coded separately or combined depending on the circumstances of the injury.
Step-by-step explanation:
The coding of fractures in the maxilla and mandible depends on the specific circumstances of the injury. In general, if both the maxilla and mandible are fractured as separate injuries, they would be coded separately using the appropriate codes from the International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM). However, if the fractures are part of the same injury or trauma, they would be coded together as a combined fracture. It is important to accurately document the details of the injury and consult the coding guidelines to ensure proper coding.
