Unsp fx lower end of left femur, subs for clos fx w malunion

This code indicates a patient is being seen for follow-up care of a previously diagnosed, non-specific fracture of the lower end of their left femur. The fracture was closed (skin intact) and has healed incorrectly, resulting in malunion. This code signifies that the malunion is being addressed or monitored during this encounter.

This code is appropriate for subsequent visits where a patient with a malunited, unspecified closed fracture of the distal left femur is being evaluated. This includes appointments for physical therapy, imaging to assess the malunion, or discussions regarding potential surgical correction of the malunion. It would also be used for ongoing management of symptoms related to the malunion.

• Ensure documentation clearly states "malunion" and specifies the "left femur" and "lower end."
• Verify that the encounter is indeed "subsequent" to the initial fracture treatment.
• Do not use for initial fracture care or for nonunion (failure to heal).
