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

This code signifies a fracture of the growth plate (physis) at the top of the right thigh bone, excluding epiphyseal separation. The fracture is not healing as expected, indicating a nonunion, and the patient is presenting for follow-up care or treatment related to this ongoing issue.

Apply this code when a patient with a previously diagnosed physeal fracture of the upper right femur is seen for management of a confirmed nonunion. This includes visits for surgical planning, cast changes, or monitoring of the nonunion's progression. It is appropriate for any encounter after the initial treatment of the fracture, where the nonunion is the primary focus.

• Ensure documentation clearly states "nonunion" and specifies the "subsequent encounter" for this specific fracture.
• Verify the fracture location is the "upper end of the right femur" and involves the physis.
• Distinguish from malunion; nonunion implies a complete cessation of healing.
