Maxillary fracture, unspecified side, 7thK

This code signifies a fracture of the upper jaw bone (maxilla) where the specific side (left or right) is not documented. The fracture has failed to heal properly after the initial treatment, and the patient is receiving active treatment for this nonunion during the current encounter.

Apply this code when a patient presents for ongoing management of a previously treated maxillary fracture that has not united. Documentation should clearly state "nonunion" of the maxillary fracture and indicate that the encounter is for active treatment of this complication, such as surgical intervention, bone grafting, or specialized follow-up.

• Ensure documentation explicitly states "nonunion" and that the encounter is for subsequent care of the fracture.
• Do not use this code for initial treatment of a maxillary fracture or for routine follow-up of a healing fracture.
• Verify laterality if documented; if specified, a more precise code (e.g., S02.401A for initial, S02.401D for subsequent with routine healing) would be appropriate.
