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

This code signifies a previously treated, but now improperly healed, growth plate fracture at the distal end of the right thigh bone. The malunion indicates that the bone fragments have united in an anatomically incorrect position, potentially leading to limb length discrepancy or angular deformity. This diagnosis is made during a follow-up visit after initial treatment.

Apply this code when a patient presents for ongoing management of a right distal femoral physeal fracture that has healed with malunion. This would include clinic visits for assessment of the malunion, planning for corrective surgery, or monitoring the effects of the malunion. It is used for encounters occurring after the initial treatment phase.

• Ensure documentation clearly states "malunion" and specifies the right femur and physeal fracture.
• Verify this is a subsequent encounter, not the initial treatment or a nonunion.
• Confirm the laterality (right) is explicitly documented.
