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

This code describes a situation where a patient has a left femur shaft fracture that broke into multiple pieces (segmental) and is no longer in proper alignment (displaced). This specific code is used when the fracture has previously been treated, but has healed in an unsatisfactory position (malunion), and the patient is now presenting for further care of this closed fracture.

Use this code for follow-up encounters for a patient with a documented segmental, displaced fracture of the shaft of the left femur that has healed incorrectly, resulting in malunion. This applies when the fracture is still considered closed, meaning the skin over the fracture site is intact. This code would be appropriate for visits related to assessing the malunion, planning corrective surgery, or managing complications arising from the malunion.

• Confirm documentation specifies "segmental" and "displaced" for the left femur shaft.
• Verify the encounter is for a "subsequent encounter" and the fracture is "closed" with "malunion."
• Do not use for initial treatment or for nonunion; specific codes exist for those scenarios.
