Unsp physeal fx upper end of r femur, subs for fx w malunion

This code signifies a follow-up encounter for a fracture of the growth plate at the top of the right thigh bone, where the fracture has healed improperly (malunion). The specific type or cause of the growth plate fracture was not documented at the initial diagnosis.

This code is appropriate for subsequent visits where a patient is being managed for a previously diagnosed, unspecified physeal fracture of the upper right femur that has resulted in malunion. This could include evaluation of the malunion, planning for corrective surgery, or ongoing conservative management of the poorly healed fracture.

• Ensure documentation clearly states "malunion" and specifies the "subsequent encounter" for this condition.
• Verify the fracture location is the "upper end of the right femur" and involves the "physeal" (growth plate) region.
• Do not use this code for initial treatment of the fracture or for nonunion; separate codes exist for those scenarios.
