Oth physeal fx lower end of l femur, subs for fx w nonunion

This code signifies a fracture of the growth plate (physis) at the lower end of the left thigh bone, which is not healing properly. It indicates that the patient is presenting for follow-up care related to this specific fracture, and the bone fragments have failed to unite after a reasonable healing period.

This code is appropriate for patients presenting for subsequent treatment of a previously diagnosed physeal fracture of the distal left femur where nonunion has been identified. This includes scenarios such as follow-up appointments for ongoing management of the nonunion, evaluation for surgical intervention to promote healing, or assessment of complications related to the nonunion.

• Always confirm the laterality (left) and the specific bone involved (femur, lower end).
• Ensure documentation clearly states "nonunion" and that this is a subsequent encounter for the fracture.
• Do not use this code for initial encounters or for fractures that are healing normally.
