Displ transverse fx shaft of r rad, 7thR

This code signifies a malunion of a previously sustained, displaced transverse fracture in the shaft of the right radius. The original fracture was an open fracture, classified as type IIIA, IIIB, or IIIC, indicating significant soft tissue damage and contamination. Malunion implies that the bone has healed in an incorrect anatomical position.

This code is appropriate for documenting follow-up care for a patient whose open transverse right radial shaft fracture (types IIIA, IIIB, or IIIC) has healed, but with a noticeable deformity or angulation. It is used when the patient is presenting for management of the malunion, such as for corrective osteotomy planning or assessment of functional limitations.

• Ensure documentation clearly specifies "malunion" and the "subsequent encounter" status.
• Verify the original fracture was indeed an open fracture of type IIIA, IIIB, or IIIC.
• Distinguish from nonunion (failure to heal) or delayed union (slow healing).
