Unsp physl fx lower end unsp femur, subs for fx w nonunion

This code describes a fracture of the growth plate at the distal end of the femur, where the specific type of physeal fracture is not documented. Importantly, this code is used when the fracture has failed to heal properly and the patient is presenting for follow-up care related to this nonunion.

Use this code for subsequent encounters when a patient is being managed for a previously diagnosed, unspecified physeal fracture of the distal femur that has not united. This would include visits for ongoing treatment, assessment of nonunion, or planning for further intervention due to the lack of healing.

• Ensure documentation clearly states "nonunion" and that the encounter is subsequent to the initial treatment.
• Verify the fracture location is the lower end of the femur and the physeal involvement is unspecified.
• Do not use for initial encounters or for fractures that are healing normally.
