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

This code signifies a follow-up encounter for a previously diagnosed fracture of the lower part of the femur, where the specific location of the fracture was not documented. The fracture has since healed in an unsatisfactory position, known as a malunion, and the skin over the fracture site remains intact (closed).

This code is appropriate for subsequent visits where a patient is being managed for a malunited closed fracture of the distal femur, and the precise anatomical location of the fracture was not specified in the initial diagnosis. This includes situations where the malunion is being monitored or treated non-surgically.

• Ensure documentation clearly states "malunion" and "subsequent encounter" for a closed fracture.
• Only use this code when the specific location of the distal femoral fracture (e.g., supracondylar, condylar) is not documented.
• Do not use for initial encounters or for fractures that are healing normally or with nonunion.
