Displ apophyseal fx unsp femur, subs for clos fx w malunion

This code indicates a fracture of the growth plate (apophysis) of an unspecified femur that has healed incorrectly (malunion) and is currently being treated. The fracture was displaced, meaning the bone fragments were not in their normal alignment. This code is used for follow-up care of a closed fracture, where the skin remained intact.

This code is appropriate for encounters where a patient is receiving ongoing treatment for a previously diagnosed apophyseal fracture of the femur that has healed with malunion. This could include physical therapy, imaging to assess the malunion, or discussions about potential corrective procedures. It specifically applies when the initial injury was a closed fracture.

• Ensure documentation clearly states "malunion" and that the encounter is for follow-up care of a closed fracture.
• Verify that the fracture is specifically an "apophyseal" fracture, not another type of femoral fracture.
• Confirm that the encounter is a "subsequent encounter" for the fracture, not the initial treatment.
