Displ commnt fx shaft of unsp tibia, 7thK

This code signifies a complex fracture involving the shaft of the tibia that has broken into multiple pieces and is no longer in its proper anatomical alignment. The patient is in a subsequent phase of care for this closed fracture, and the bone fragments are failing to heal together as expected.

Apply this code when documenting ongoing treatment for a comminuted tibial shaft fracture that was initially closed, and the physician has identified nonunion during a follow-up visit. This is appropriate for situations where the patient is receiving continued care, such as cast changes, physical therapy, or preparation for revision surgery, due to the lack of healing.

• Ensure documentation clearly states "nonunion" for a closed comminuted fracture of the tibial shaft.
• Verify the encounter is "subsequent" and not initial care for the fracture.
• Confirm the fracture is of the shaft and not another part of the tibia.
