Maxillary fracture, right side, 7thK

This code describes a fracture of the right maxilla that has failed to heal properly, and the patient is presenting for follow-up care related to this nonunion. A nonunion indicates that the bone ends have not united and the healing process has ceased. This code is used when the patient is receiving routine care during the healing or recovery phase of the nonunion.

Use this code for patients presenting for ongoing management of a previously diagnosed right maxillary fracture that has progressed to nonunion. Documentation should clearly state "nonunion" of the right maxilla and indicate that the encounter is for follow-up care, such as cast changes, medication adjustments, or monitoring of the nonunion.

• Always confirm laterality (right vs. left) for maxillary fractures.
• Distinguish between "subsequent encounter for fracture with nonunion" and "subsequent encounter for fracture with routine healing" (S02.40CJ) or "subsequent encounter for fracture with delayed healing" (S02.40CL).
• Ensure documentation explicitly states "nonunion" and the encounter type (e.g., follow-up, management of nonunion).
