Unsp fx shaft of left femur, subs for clos fx w malunion

This code indicates a follow-up visit for a patient who previously sustained an unspecified fracture of the shaft of their left femur. At the time of this encounter, the fracture is closed (skin intact) but has healed improperly, resulting in a malunion.

This code is appropriate for documenting subsequent care related to a left femoral shaft fracture that has healed with an anatomical deformity. This includes appointments for evaluation of the malunion, planning for corrective surgery, or monitoring the functional impact of the malunion.

• Ensure documentation clearly specifies "left femur" and "shaft" to support this code.
• Verify the encounter is for a "subsequent" visit and that the fracture is "closed" and has resulted in "malunion."
• Do not use for initial fracture treatment or for nonunion, which has a separate code.
