Displ subtrochnt fx l femr, 7thR

This code signifies a subtrochanteric fracture of the left femur that has healed in an unsatisfactory position (malunion). It specifically applies to a fracture that was initially open, classified as type IIIA, IIIB, or IIIC, and is now being treated during a subsequent encounter for the malunion.

This code is used when a patient presents for follow-up care or treatment of a malunion stemming from a previously sustained open subtrochanteric fracture of the left femur. This includes scenarios where surgical correction of the malunion is being planned or performed, or during ongoing management of the malunited fracture.

• Ensure documentation clearly specifies "malunion" and not nonunion or delayed union.
• Verify the fracture was initially an "open" fracture of type IIIA, IIIB, or IIIC.
• Confirm this is a "subsequent encounter" for the malunion, not the initial treatment of the acute fracture.
