Displ apophyseal fx l femur, subs for clos fx w delay heal

This code signifies a fracture occurring at the growth plate (apophysis) of the left thigh bone, which is no longer in its correct anatomical alignment. The patient is in a later stage of recovery, and the fracture is not healing at the expected rate, but the skin over the fracture site remains intact.

Apply this code for follow-up encounters where a patient with a previously diagnosed displaced apophyseal fracture of the left femur is experiencing delayed union. This is appropriate when the fracture is still being managed non-surgically or post-reduction, and the physician documents slow or insufficient healing progress.

• Ensure documentation explicitly states "delayed healing" and confirms the fracture is "closed."
• Verify the fracture location is specifically the apophysis of the left femur.
• This code is for subsequent encounters, not the initial treatment of the fracture.
