Displ transverse fx shaft of r tibia, 7thR

This code signifies a previously treated transverse fracture of the shaft of the right tibia that was an open fracture (Type IIIA, IIIB, or IIIC) and has subsequently healed in a misaligned position. It indicates a complication of healing where the bone fragments have united but with an unacceptable degree of angulation, rotation, or shortening.

This code is appropriate for documenting follow-up care for a patient who sustained a severe open transverse tibial shaft fracture on the right side, and during the healing process, the bone fragments have united improperly, resulting in malunion. It would be used when the patient presents for evaluation or management of this malunion, such as for corrective osteotomy planning or assessment of functional impairment.

• Ensure documentation clearly specifies "malunion" as the healing outcome, not nonunion or delayed union.
• Verify the fracture was initially classified as an open fracture type IIIA, IIIB, or IIIC.
• Confirm this is a subsequent encounter for the fracture, not the initial treatment.
