Unsp physl fx low end ulna, left arm, subs for fx w nonunion

This code signifies an unspecified growth plate fracture at the distal end of the left ulna that has failed to heal properly. It indicates that the patient is presenting for ongoing treatment or management of this specific fracture complication. The "unspecified" nature means the exact type of physeal fracture is not documented.

This code is appropriate for follow-up encounters where a patient is being treated for a previously diagnosed, non-healing growth plate fracture of the left distal ulna. This includes visits for cast changes, physical therapy, surgical planning for nonunion, or monitoring the progress of nonunion treatment. It should be used when the initial injury has already been established and the focus is on the persistent lack of healing.

• Always ensure documentation clearly states "nonunion" for this specific fracture site and laterality.
• Verify that the encounter is subsequent to the initial injury and treatment, not the initial diagnosis.
• Do not use this code if the fracture is healing normally or if the specific type of physeal fracture is documented (e.g., Salter-Harris type).
