Displ transverse fx shaft of l tibia, 7thR

This code describes a situation where a patient has a transverse fracture of the shaft of their left tibia that is displaced, and the fracture was initially an open fracture (Type IIIA, IIIB, or IIIC). The current encounter is for the management of a malunion, meaning the fracture has healed in an unsatisfactory position or alignment.

This code is used when a patient presents for follow-up care, treatment, or evaluation of a malunion of a previously sustained displaced transverse open fracture of the left tibial shaft. This would include scenarios such as surgical correction of the malunion, cast changes, physical therapy, or imaging to assess the malunion.

• Ensure the documentation clearly specifies "malunion" as the reason for the subsequent encounter, not nonunion or routine healing.
• Verify the original fracture was indeed an open fracture of Type IIIA, IIIB, or IIIC, and that the fracture was displaced and transverse.
• This code is for the left tibia; confirm laterality in the medical record.
