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

This code signifies a healing fracture of the growth plate at the top of the right thigh bone that has healed incorrectly. This malunion indicates that the bone fragments have joined in a deformed or misaligned position, potentially leading to functional impairment or limb length discrepancy.

This code is appropriate for follow-up encounters where a patient is being treated for a previously diagnosed physeal fracture of the right proximal femur that has healed in a malunited fashion. It is used when the malunion itself is the focus of the current encounter, such as for evaluation, monitoring, or planning corrective procedures.

• Ensure documentation clearly specifies "malunion" and not "nonunion" or "delayed union."
• Verify the encounter is "subsequent" and not an initial treatment for the fracture.
• Confirm the fracture location is the "upper end of the right femur" and involves the physis.
