Unsp physl fx lower end of l femur, subs for fx w delay heal

This code signifies a fracture of the growth plate (physis) at the lower end of the left thigh bone, where the specific type of physeal fracture is not documented. It is used when the patient is seen for follow-up care and the fracture is not healing at the expected rate.

Apply this code for a patient presenting for a subsequent visit related to an unclassified physeal fracture of the distal left femur, and the physician's documentation indicates delayed union or non-progression of healing. This would include scenarios where imaging shows persistent fracture lines or callus formation is insufficient for the stage of healing.

• Ensure documentation clearly specifies "delayed healing" for the subsequent encounter.
• Verify the fracture location is the lower end of the left femur and the fracture type is unspecified physeal.
• Do not use this code for initial encounters or for fractures healing normally.
