Displ seg fx shaft of l fibula, subs for clos fx w malunion

This code signifies a left fibular shaft fracture that has broken into multiple pieces (segmental) and is no longer in its proper anatomical alignment (displaced). The patient is in a later stage of care for this injury, specifically addressing a complication where the bone has healed incorrectly, resulting in a deformity (malunion), and the fracture site is not open to the external environment (closed).

Apply this code when documenting a patient presenting for follow-up care, evaluation, or treatment of a previously sustained displaced segmental fracture of the left fibula shaft. The key clinical indicators are the presence of malunion and the closed nature of the original fracture. This would be used for patients undergoing assessment for corrective surgery or ongoing management of the malunion.

• Ensure documentation clearly specifies "segmental" and "displaced" for the left fibula shaft fracture.
• Verify that the encounter is for a "subsequent encounter" and that "malunion" is explicitly documented as a complication.
• Confirm the fracture was "closed" at the time of the initial injury and remains so.
