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

This code describes a situation where a patient has previously sustained an unspecified fracture of the lower end of their right femur, and the fracture is now healing incorrectly (malunion). The fracture itself is closed, meaning the skin was not broken at the time of the injury. This code is used during follow-up care for this specific complication.

Use this code when documenting subsequent encounters for a patient with a previously diagnosed, unspecified closed fracture of the distal right femur that is now exhibiting malunion. This would apply during orthopedic follow-up visits, physical therapy, or other care related to managing the malunion.

• Ensure documentation clearly specifies "malunion" as the complication of the fracture healing.
• Verify the encounter is "subsequent" and not the initial treatment for the fracture.
• Confirm the fracture is of the "lower end" (distal) of the right femur and that the fracture type remains "unspecified."
