Nondisp seg fx shaft of l femur, subs for clos fx w malunion

This code describes a situation where a patient has a segmental fracture in the shaft of their left femur that was initially nondisplaced, but has subsequently healed improperly (malunion). The encounter being coded is for follow-up care of this closed fracture with the noted malunion.

This code is appropriate for encounters where a patient is being treated for complications arising from a previously sustained, closed, nondisplaced segmental fracture of the left femoral shaft, specifically when that fracture has healed with malunion. This would include follow-up appointments, imaging studies, or discussions regarding the malunion.

• Ensure documentation clearly specifies "malunion" as the complication of the healing fracture.
• Verify the encounter is "subsequent" and not initial or sequela.
• Confirm the fracture location is the shaft of the left femur and is segmental.
