Nondisp seg fx shaft of unsp tibia, 7thR

This code signifies a complex healing issue following a severe open fracture of the tibia. Specifically, it indicates that a patient previously sustained a segmental fracture of the tibial shaft, which was an open fracture of type IIIA, IIIB, or IIIC, and is now experiencing malunion. The fracture itself is currently nondisplaced.

This code is appropriate for follow-up encounters where a patient is being treated for a malunion of a previously sustained, severe open tibial shaft fracture. It should be used when the fracture is no longer displaced but has healed in an anatomically incorrect position. This code would be relevant for ongoing management, such as planning for corrective osteotomy or monitoring the malunion.

• Ensure documentation clearly specifies "malunion" and the original open fracture type (IIIA, IIIB, or IIIC).
• Verify that the encounter is "subsequent" and not initial care for the fracture.
• Confirm the fracture is of the "shaft" of the tibia and is currently "nondisplaced."
